250 words or less): Phosphorus loadings from the Maumee River watershed have significantly compromised the Lake Erie ecosystem, as evidenced by the most severe harmful algal bloom in Lake Erie in 2015 and the shut-down of Toledo drinking water supply in 2014. Despite government payments for adoption of voluntary conservation practices, excess nutrient runoff from agricultural production remains...

The northern region of Algeria is experiencing a real threat to the spatial extension soil erosion. Oued Bouhamdane watershed, part this region, brings together all natural and anthropogenic conditions that accelerate its degradation. This study based on use remote sensing GIS map erosion in watershed north-eastern Algeria, using Gavrilovic equation. combination data from different sources fiel...

The purpose of the modern watershed study is to use a regional pilot to select an erosion sub-basin and restore it to preserve the downstream wetland. In this research, Alanza watershed, located in the upstream reaches of Anzali wetland, has been selected as a sub-watershed (pilot) with the aim of investigating the effect of mechanical, biological and biomechanical operations on modern watershe...

one of the most important problems in schematization and watershed management is determining the watershed measures impacts on flow distribution. flow distribution algorithms grouped into two main types include single flow direction (sfd) algorithm and multiple flow direction (mfd) algorithms. in many package of gis use the single flow direction to runoff routing. in this research studied water...

soil erosion is a serious environmental problem in vazroud watershed, which is located in the centre of the mazandaran province, iran. unfortunately, vazroud watershed like most iran watersheds don’t have recorded data and erosion and sedimentation gages to research, monitor and model soil erosion at large watershed. in order to assess the soil erosion risk, soil erosion modeling at the watersh...

Watershed management and water yield augmentation have been important objectives for chaparral, ponderosa pine, and mixed conifer management in Arizona and New Mexico. The ponderosa pine forests and other vegetation types generally occur in relatively high precipitation zones where the potential for increased water yields is great. The ponderosa pine forests have been the subject of numerous re...
