[1] The focus in the search for more reliable predictions in ungauged basins (PUB) has generally been on reducing uncertainty in watershed models (mainly their parameters). More recently, however, we seem to remember that the ultimate objective is not to define the parameters of a specific model but to understand the watershed: What behavior do we expect the ungauged watershed to exhibit? And w...

Soil erosion, due to intensive agricultural practices, has been and continues to be of significant concern in the Whitewater Watershed, a coldwater tributary of the Mississippi River, in southeastern Minnesota. Conservation efforts, in the form of best management practices (BMPs) have been underway for many years and a number of residents have enrolled in various government programs designed to...

in order to determine hydrological behavior and water management of sepidroud river (north of iran-guilan) the present study has focused on stream flow prediction by using artificial neural network. ten years observed inflow data (2000-2009) of sepidroud river were selected; then these data have been forecasted by using neural network. finally, predicted results are compared to the observed dat...

An approach to developing and using Bayesian networks to model watershed management decisions is presented with a case study application to phosphorous management in the East Canyon watershed in Northern Utah, USA. The Bayesian network analysis includes a graphical model of the key variables in the system and conditional and marginal probability distributions derived from a variety of data and ...

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...
