Simulation models are powerful tools in support of watershed analysis and assessment of management scenarios at the watershed scale. This paper integrates geographic information systems (GIS) and agricultural nonpoint source pollution model (AGNPS) to analyze the effect of land use change on nonpoint source pollution in a study watershed. ArcView nonpoint source pollution modeling (AVNPSM), an ...

Watershed management and planning is a complex decision-making process, which not only involves deliberation using one or more watershed models, but also requires collaboration among multiple stakeholder groups with different ideologies, interests, and demographics. Web-based decision support tools have great potentials to enhance the transparency and participation of such decision making proce...

The tenets of watershed management – a focus on the land area linked to the water body, the incorporation of sound scientific information into the decision-making process and stakeholder involvement throughout the process – are well-suited for the management of cyanobacterial harmful algal blooms (C-HABs). The management of C-HABs can be viewed as having two main areas of focus. First, there is...

There has been considerable work on determining a suitable method to accomplish a satisfactory ordering of a group of objects, when there are multiple evaluation criteria. A weighted index can be used to combine the opinion of all stakeholders to obtain a criterion for ranking the objects. Data from 21 watersheds of the Atlantic Slope Consortium (ASC) has been examined with the goal of determin...

Quantifying the effects of forest changes on hydrology in large watersheds is important for designing forest or land management and adaptation strategies for watershed ecosystem sustainability. Minjiang River watershed, located in the upper reach of the Yangtze River basin, plays a strategic role in the environmental protection and economic and social well-being for both the watershed and the e...

The implementation of stormwater Best Management Practices (BMPs) could help re-establish the natural hydrological cycle of watersheds after urbanization, with each BMP presenting a different performance across a range of criteria (flood prevention, pollutant removal, etc.). Additionally, conflicting views from the relevant stakeholders may arise, resulting in a complex selection process. This ...

The upsurge of interest in watershed management and planning has increased the need for user friendly, interactive methods that decision makers can use to evaluate the economic and environmental consequences of alternative land use/management practices (LUMPs). Knowledge and information from several disciplines are integrated into a functional computer-based watershed management decision suppor...
