Non-point source pollution is well recognized as one of the most critical environmental hazards of modern times. In Illinois, non-point source pollution is the major cause of water quality problems, and soil erosion from agricultural lands is the major source of such pollution. Accelerated by anthropogenic activities, soil erosion reduces crop productivity and leads to subsequent problems from ...

Watershed management, in its very nature, represents a participatory process, requiring horizontal and vertical collaborations among multiple institutions and stakeholders. For watershed-scale management to be effective, a social-learning infrastructure needs to be in place to allow for the integration of diverse knowledge and interests related to watershed protection and restoration. Environme...

with regard to the importance of instantaneous peak discharge estimation for watershed management study, and due to the lack of and unqualified climatic and hydrologic data for estimation and measurement in countries such as iran, researchers were obliged to establish a link between constant parameters (geomorphologic) and variables (hydrologic) to present models with minimum dependence on clim...

Community-based watershed management (CBWM) has gained prominence in developing world towards integrated resource management for livelihood enhancement of the poor, due to failure of large-scale river valley projects. This paradigm shift has enabled to narrow the divide between the state and community, and marks a beginning for the State towards a "learning organisation" that is adaptive to the...

In many locations around the globe, large reservoir sustainability is threatened by land use change and direct pollution loading from the upstream watershed. However, the size and complexity of upstream basins makes the planning and implementation of watershed-scale pollution management a challenge. In this study, we established an evaluation system based on 17 factors, representing the potenti...

Organizations increasingly create massive internal digital data repositories and are looking for technical advances in managing, exchanging and integrating explicit knowledge. While most of the enabling technologies for knowledge management have been used around for several years, the ability to cost effective data sharing, integration and analysis into a cohesive infrastructure evaded organiza...

The stakeholders’ involvement in any decision making process is a key point in the Integrated Water Management (IWM). A successful watershed management process has to be participatory, allowing the stakeholders working together to set criteria for sustainable management, to identify priorities and constraints, to evaluate possible solutions, to recommend technologies and policies, and, finally,...

AnnAGNPS (Annualized AGricultural Non-point Source), a continuous simulation and distributed pollution model, is widely applied in evaluating non-point source pollution and watershed management practices. However, the complexity of required input data and modeling procedure keep it from being an efficient modeling tool. An integrated GIS interface was developed to facilitate organizing and prep...

Forest Watersheds provide timber and water, wildlife and fisheries habitat, and recreational opportunities. However, not an entire watershed is equally suited for each activity. Steeper slopes may be better left forested and used for wildlife habitat while more gentle slopes of the watershed could be used for timber production. Logging steep slopes can lead to soil erosion that can.seriously de...
