Microbial Source Tracking within your watershed can provide important information regarding the Point Source (structures, pipes, sewage outfalls) and Non-Point Source (runoff, animals) contamination present in your service area. Determination of human, ruminant and other fecal inputs into surface source or ground waters can provide a scientific basis for watershed management decisions and can a...

This article emphasizes the critical role of local policy networks for the implementation of agricultural watershed management and the adoption of environmental best management practices. Local networks facilitate diffusion of innovations, the development of social capital, and cultural change. All of these elements are essential for the ability of watershed management programs to successfully ...

We analyzed data from riffle and snag habitats for 39 small cold water streams with different levels of watershed urbanization in Wisconsin and Minnesota to evaluate the influences of urban land use and instream habitat on macroinvertebrate communities. Multivariate analysis indicated that stream temperature and amount of urban land use in the watersheds were the most influential factors determ...

Index words: Watershed studies Best Management Practices Restoration Remediation Aquatic systems Studies that evaluate the linkages between watershed improvement through Best Management Practices (BMPs) and downstream outcomes are few. Water quality of coastal waters is often impacted by soil and nutrient loss fromwatersheds in agriculture. Mitigation of these impacts is of concern in the Great...

Implementing a suite of best management practices (BMPs) can reduce non-point source (NPS) pollutants from various land use activities. Watershed models are generally used to evaluate the effectiveness of BMP performance in improving water quality as the basis for watershed management recommendations. This study evaluates 171 management practice combinations that incorporate nutrient managemen...

The number of states that have adopted numeric nutrient water-quality standards has increased to 23, up from ten in 1998. One state with both stream and reservoir phosphorus (P) numeric water-quality standards is Oklahoma. There were two primary objectives of this research: (1) determine if Oklahoma was meeting the stream and reservoir numeric water-quality standards in the Illinois River and E...

Soil erosion has been recognized as one of the major threats to our environment and water quality worldwide, especially in China. To mitigate nonpoint source water quality problems caused by soil erosion, best management practices (BMPs) and/or conservation programs have been adopted. Watershed models, such as the Annualized Agricultural Non-Point Source Pollutant Loading model (AnnAGNPS), have...

This paper focuses the quantitative evaluation of non point sources of pollution by graphical maps of watershed and estimating area based load of pollutants of various land uses with the use of Arc/View Geographic Information System. The representative study is carried out in the Xinshan sub-watershed of Taihu watershed. It involves the simulation of pollutants load by watershed; watershed area...
