watershed management meaning

Types of Watershed Management 3. For example, the check dam led to a rise in groundwater levels, which led an increasing number of villagers to build shallow tubewells and use these tubewells rather than the check dam for irrigation water; this development lowered the incentives for limiting watershed grazing and participating in communal activities. The District takes a watershed approach to managing water and water-related resources within its boundaries. Moreover, organizing collective action at the micro-watershed level has generally proved to result in lower costs and in improved use of financial and human resources, particularly for the management of common resources. The important question regarding the trade-off between operating at an optimal hydrologic unit and an optimal social unit is its severity. This approach is necessary due to the nature of polluted runoff, which in most watersheds is the biggest contributor to water pollution. (2003) noticed that successful water harvesting in upper watersheds came at the expense of lower watershed areas. (iii) National Watershed Development Programme for Rainfed Agriculture (NWDPRA): Objectives: To conserve and utilize rain water from both arable and non arable lands on watershed basis. Of late, the pendulum has swung in the opposite direction, and now, most projects operate at the village level, disregarding hydrologic linkages between micro watersheds. “All the areas from which water flows out into a river or water pool”. Research has revealed that the micro-watershed approach may be producing hydrologic problems that would be best addressed by operating at a macro-watershed scale. First, projects with high investment in social organization may not be replicable beyond a small number of cases. On the following pages are 6 examples of successful watershed A watershed embraces physical-biological features as well as socio-economic and political features which have to be integrated into the planning and management process. A watershed can be small, such as a modest inland lake or a single county. M. Dinesh Kumar, ... A.J. Put simply, a Watershed Management Plan (WMP) identifies water quality problems in your watershed, proposes solutions, and creates a strategy for putting those solutions in action. Therefore any generalized approach to watershed management must be customized to each setting when put into practice. All the area under winter crops (mostly maize) and the small area under the summer groundnut crop are irrigated. All environmental, social, and economic concerns are combined to treat watersheds in an integrated manner. The field of water resources management will have to continue to adapt to the current and future issues facing the allocation of water. Disclaimer 9. M.D. By continuing you agree to the use of cookies. Watershed management has existed for millennia [7]; nevertheless, a holistic and bottom-up approach [8] has only emerged since the 1970s. Water development and management should be based on a participatory approach, involving users, planners, and policy-makers at all levels. (v) World Bank Assisted Integrated Watershed Development Project: Objectives: To arrest the problems of environmental degradation and promote sustainable increase in agriculture production and to enhance vegetative technology of soil and water conservation for rain water conservation and for increasing crop, forage, fuel wood and timber yield of the area. Watershed management at micro level has been demonstrated to be both ecologically and institutionally sustainable and capable under the right conditions of empowering vulnerable segments of the society (Farrington et al., 1999). II to discover new tools and programs that you can incorporate into your watershed management activities. Watershed management is a term used to describe the process of implementing land use practices and water management practices to protect and improve the quality of the water and other natural resources within a watershed by managing the use of those land and water resources in a comprehensive manner. An appreciable amount of precipitation, which is generally lost as surface flow, can be harvested and stored for useful purposes like drinking and providing supplemental irrigation to the crops. The hydrological assessment crosses the sectors of the economy, energy, agriculture, and environment [16] and looks for water quantity, quality, and demand [10]. Watershed management is the study of the relevant characteristics of a watershed aimed at the sustainable distribution of its resources and the process of creating and implementing plans, programs and projects to sustain and enhance watershed functions that affect the plant, animal, and human communities within the watershed boundary. All lands on earth are part of one watershed or other. And there is no specific allocation of resources for watershed management and lack of emphasis on ground-level coordination (Tsering, 2011). The basis for achieving results from such modifications within watersheds is through understanding how threshold behavior in hydrological systems can be exploited to achieve or regain stability. There are large variations in rainfall, evapotranspiration, and runoff across dry and wet years that affect inflows into the reservoir, which, in turn, affect canal releases to downstream communities. TOS 7. (e) Planting of horticultural contour species on bunds. Prior to 2009, WSM projects were implemented with donor support. Examples from selected case studies on the efficiency of ecological engineering measures in watershed management are presented. Molle [14] qualified IWRM as a nirvana concept, an ideal image of what the world should tend toward, but which is unreachable. The Dublin Statement on Water and Sustainable Development set out four guiding principles: Freshwater is a finite and vulnerable resource, essential to sustain life, development, and the environment. watershed management program are: 1) conservation, up-gradation and utilization of natural endowments such as land, water, plant, animal and human resources in a harmonious and integrated manner with low-cost, simple, e/ective and replicable This phase takes care of the general health of the watershed and ensures normal functioning. However, they also remark that it requires careful institutional organization upfront to coordinate research agencies at various levels and to factor in other stakeholders, including farmers and the private sector. Watershed-management experiences from around the globe have dealt with a wide range of issues. ; To manage and utilize the runoff water for the useful purpose. To increase the productivity of crops and to increase the fuel, fodder and fruit resources through appropriate alternate land use system. While, successful watershed projects have overcome the inherent constraints to collective action, they have not overcome two outstanding barriers. A Watershed Management Plan is an important tool for any group looking to improve their local lake, river or stream. Climate change is progressively modifying both plant water demand and the water available from rainfall. Water resource management plays a vital role in sustainable development of watershed which is possible only through the implementation of various water harvesting technique. This phase deals with overall improvement in the watershed and all land is covered. The micro-watershed approach enables amicable integration of land, water, and infrastructure development, particularly because of the homogenous nature of soil, water, and overall physical conditions within the micro watershed. These programs did not have any common objective or framework. watershed synonyms, watershed pronunciation, watershed translation, English dictionary definition of watershed. Foresight, commitment, and long-term investments have the capacity for substantial benefits. Ü. Mander, in Encyclopedia of Ecology, 2008. The figure below demonstrates the Watershed Approach to … Theory and experience have shown that facilitating collective action in small, village-level watersheds has fewer constraints. Adapted from FAO (Ed. The hilly and rocky Upper Sukhi watershed has relatively high rainfall, occurring in a few months in a year resulting in high-velocity flows that do not allow water harvesting structures to remain intact and functional along the main streams. When rain water, also referred to as stormwater, hits the earth, it either soaks into the ground, or it runs over the surface until it reaches a surface water. The various measures adopted under soil and water harvesting is: (b) Building of contour bunds along contours for erosion. Objectives: Area development programme through restoration of ecological balance and optimum utilization of land, water, livestock and human resources to mitigate the effect of drought. Watershed management is thus appropriate use and management of soil, water and vegetation to result in optimum use of water and for preservation of the soil layer. Prohibited Content 3. A watershed is simply the geographic area through which water flows across the land and drains into a common body of water, whether a … Watershed Management What is a watershed? Watershed management is a primary and essential component of environmental planning, which is usually focused on the built environment. Audience for the Quick Guide The Quick Guide is intended for novice as well as experienced practitioners working on watershed-related issues at the federal, state, tribal, and local levels. More wells and RWH structures built in the last decade has supported a growth in irrigated agriculture in (micro) watershed villages. [9] note that the most successful applied research and knowledge sharing in watershed management programs worldwide occur when stakeholders are full partners in the research process at all the stages of identification, design, implementation, and evaluation, and technologies are offered as a range of choices to be adapted. Most structures built on the upper reaches of the main streams flowing into the reservoir have been broken by the monsoon rainwater carrying branches and boulders, and there is not much space in villages to build additional RWH structures. The difficulty of managing watershed interventions at diverse scales so as to achieve the larger-scale objectives of downstream impacts is further complicated because of participatory approaches, which basically give the option of interventions to the communities rather than to the planners. Watershed management was part of many activities and programs implemented by different departments. A watershed, also called a "drainage basin" in North America, is an area in which all water flowing into it goes to a common outlet or body of water, such as the same estuary or reservoir.Watersheds themselves consist of all surface water and include lakes, streams, reservoirs, and wetlands, as well as all groundwater and aquifers. (i) Vegetative measures/Agronomical measures: (ii) Engineering measures/Structural practices: (i) Establishment of permanent grass and vegetation, (j) Providing vegetative and stone barriers. Hydraulic works may increase the impact of floods, especially the larger ones (e.g., river channeling). The pollution is concentrated in rivers, threatening human health and ecosystems. Watershed Definition Watershed refers to an area of land where all the water drains to a central point, such as lake, river or stream. Women play a central part in the provision, management, and safeguarding of water. But none of them have provided any clear guidelines and objectives or institutional framework for implementing the program. A shed that holds water? Plagiarism Prevention 4. Darghouth et al. A watershed or a catchment is a piece of land or an area that drains rainwater into a lake, river or stream. Sometimes the hydrological benefits of land-management changes, such as changing conventional agricultural practices to conservation practices (e.g., cover cropping and no-till farming) are slow and incremental. Even the Constitution of Bhutan mentions about, Sally L. Letsinger, ... Erin K. Hiatt, in, Modeling for integrated water resources management in the Mediterranean region, Water Resources in the Mediterranean Region. Both the efficiency assessment of buffer zones and strips in watershed management and the estimation of landscape potential for optimal location of constructed wetlands in catchments are considered. (c) Furrow/Ridges and Furrow ridge method of cultivation across the slope. A watershed refers to an area of land that comprises a set of streams or rivers that drain into a larger water body like an ocean or a river. Objectives 4. Concepts of Watershed Management Soil, vegetation and water are most important vital natural resources for the existence of the man and his animals. These issues are unique to each watershed and each nation. However, the reverse is also true, to some degree. Watershed management programs have usually paid attention to on-site interventions and their benefits. The premise of this concept is that many water quality and ecosystem problems are best prioritized, addressed, and solved at the watershed level rather than at the individual waterbody level. On one side of the debate are those who think the word can only refer to a ridge of land separating rivers and streams flowing in one direction from those flowing in the opposite direction. IWRM is, therefore, a holistic approach to water management involving technical, economic, financial, and institutional aspects [8]. Content Filtrations 6. R. Lenton, in Treatise on Water Science, 2011. Watershed is thus the land and water area, which contributes runoff to a common point. In this case, watershed development checks the movements of both surface runoff and groundwater toward downstream. Before publishing your articles on this site, please read the following pages: 1. This section introduces the principles of the watershed approach and the … Sally L. Letsinger, ... Erin K. Hiatt, in Encyclopedia of Geology (Second Edition), 2021. The size of a watershed (also called a drainage basin or catchment) is defined on several scales—referred to as its Hydrologic Unit Codes (HUC)—based on the geography that is most relevant to its specific area. Similarly, stakeholder involvement and participation normally covered on-site requirements of local farmers, and the spatial dimension was tackled through community-based planning of their region.

In many cases, anthropogenic or natural disruptions have caused changes on short time scales and, depending on the complexity of processes interacting in the watershed, actions can sometimes be taken to trigger a desired hydrological response. The main aim of watershed management is to conserve the soil, plant, and water resources of a catchment while benefiting humanity. A wide range of quantitative and qualitative methods are available and combine disciplines such as economics, hydrology, hydraulics, environmental sciences, and sociology. Read this article to learn about Watershed Management. This scale facilitates a program to act in response to human needs and natural resource problems at the local level. Tomer, in Encyclopedia of Soils in the Environment, 2005. This would involve working simultaneously to promote watershed governance capacity both within and between micro watersheds. According to the Global Water Partnership [1], the water resources are under increasing pressure due to the demographic pressure and improved standard of living. All watersheds can be divided into smaller sub-watersheds” . Even the Constitution of Bhutan mentions about watershed management (article 5) followed by most of the recent policies and acts (Bhutan 2020; Land Act, 2007; Bhutan Water Vision 2025; Bhutan Water Policy, 2008 and Bhutan Water Act 2010). Watershed management professionals generally view that increasing the thickness of vegetative cover in the upper catchments would reduce erosion and sediment load in the runoff, and increase the base flows, irrespective of the agroecology. As a preliminary to SVP, a framework like the Transboundary Water Opportunity Analysis [20] can be useful to identify environment and ecosystem services, and to analyze the opportunities in the basin. c. Over exploitation of resources should be minimized. The competition and conflicts over freshwater resources are intensifying. Watershed is defined as a geohydrological unit draining to a common point by a system of drains.All lands on earth are part of one watershed or other. A.J. Watershed management, defined as any human action aimed at ensuring the sustainable use of natural resources in a watershed, attempts to provide solutions to these threats. f. Erosion control and prevention of soil, degradation and conservation of soil and water. It includes the transformation of water allocation, the improvement of environmental management, the reform of pricing of water services, modernization of institutions, community and stakeholder engagement, and the improvement of water information and knowledge. Watershed: Definition: “Watershed can be defined as a unit of area covers all the […] Conversely, if water resources decrease, the concentration of pollutants will increase, increasing their impact on water quality. Report a Violation, Watershed Management: Aspects, Objective and Various Measures, Measures taken by Government for the Development of Dryzone Agriculture in India. Practices. Module I: Key features of sustainable watersheds, V. Ratna Reddy, ... Chiranjeevi Tallapragada, in, Integrated Approaches to Sustainable Watershed Management in Xeric Environments. Nevertheless, after a few years of experimentation of the process, skepticism arose. There is hardly any evidence that can prove that the improved conditions in the wider watershed result as a consequence of micro-level activities and institutions at upstream level or even that the activities were optimal or cost-effective ways to improve conditions in the watershed. Meaning of Watershed Management: Watershed management in the broader sense is informed by an undertaking to maintain the equilibrium between elements of the natural eco system or vegetation, land or water on the one hand and human activities on the other hand. If the stormwater stayed clean, there would be little concern for water quality. About the Watershed Management Program. Watershed is defined as a geo-hydrological unit draining to a common point by a system of drains. Operating at the micro-watershed scale does not necessarily aggregate up or capture upstream-downstream interactions. Watershed management is aimed at land and water resources, and is applied to an area of land that drains to a defined location along a stream or river. Watch this short video to learn what a watershed really is. Watershed management is also a useful, proactive approach in areas without immediate problems. (2006) cites this as “catchment closure,” whereby water harvesting upstream accumulates groundwater locally and then intensive pumping depletes the shallow aquifer. (a) Selection of best solution to problems identified, (b) Application of the solution to the problems of the land. Good watershed management helps to … Watershed planning and management comprise an approach to protecting water quality and quantity that focuses on the whole watershed. Watershed management is the study of the relevant characteristics of a watershed aimed at the sustainable distribution of its resources and the process of creating and implementing plans, programs and projects to sustain and enhance watershed functions that affect the plant, animal, and human communities within the watershed boundary. Within the participatory approach, the assessment is also an opportunity to gather stakeholders together and build a shared vision planning (SVP) of the watershed, i.e., “computer simulation models of water systems built, reviewed, and tested collaboratively with all stakeholders” [17]. Watershed is that land area which drains or contributes runoff to a common outlet. (C) Development of alternative solutions of problem. The practitioners working in this realm are involved in an interdisciplinary endeavor, working collaboratively to study not only the storage and movement of water, but all of the interrelated systems that are dependent on water. Resolving the trade-offs is necessary for the widespread success of the watershed development program, but no obvious solutions exist. Watershed management involves determination of alternative land treatment measures for, which information about problems of land, soil, water and vegetation in the watershed is essential. Image Guidelines 5. WATERSHED MANAGEMENT. Catchment area is the water collecting area. Darghouth et al. The factors affecting water availability and demand. Watershed management approaches are evolving throughout the country and are being used to solve tough problems. Watershed management projects are generally anticipated not only to provide local on-site benefits at the micro-watershed level but also to offer positive externalities in the form of valuable environmental services downstream and to provide a means of correcting downstream negative externalities within the larger watershed. Watershed is thus the land and water area, which contributes runoff to a common point. The main objectives of the program include sustaining the flows of natural resources and better stewardship of watersheds providing the country and its people with goods and services in ways that maintain the long-term productive capacity of natural resources without damaging the environment (Tsering, 2011). Because of these multidisciplinary concerns, the development of watershed-management strategies can involve complex scientific and public policy issues. Watershed management is the integration and coordination of activities that affect the watershed's natural resources and water quality. Meaning of Watershed Management 2. The entire region draining into a river, river system, or other body of water: a list of reptiles found in the watershed. d. Water storage, flood control, checking sedimentation. From: Encyclopedia of Soils in the Environment, 2005, M.D. Interestingly, Borchardt and Ibisch [16] argue that the strong links and important trade-offs between water security, food security, and energy security mean that IWRM should be considered as a pathfinder process for the implementation of integrated resource management. Such alterations are usually undertaken to rehabilitate, protect, or enhance desired functions of a watershed for the end result that the managers are seeking. Water is essential for our survival. With the worsening of the groundwater table downstream, more intensive drilling of wells is needed, which the poor could often not afford, leading to inequitable distribution and use of water (Calder, 2005).
