Abstract: A digital elevation model (DEM) may be used in modeling direct surface runoff. Topographic variability affects the apparent slope and flow path length extracted from DEMS. Smoothing of the digital elevation data is a common ...

Abstract: Nonpoint‐pollution models estimate loadings of chemicals, sediment, and nutrients that degrade water quality. Before controls can be implemented, location and severity of pollution must be identified in the watershed basin. ...

Abstract: Storm water runoff can significantly affect flooding in urban areas. Flood prediction depends on model structure uncertainties and the accurate determination of rainfall. Three aspects of hydrologic forecasting in real ...

Abstract: The aim of this study is to evaluate prediction accuracy and sensitivity of a distributed hydrologic model. Accurate predictions of runoff are needed where reservoir operations are used to control flooding and to manage ...

Abstract: Distributed rainfall information is necessary for making operational hydrologic predictions and retrospective studies. Rainfall measurements from radar require conversion of reflectivity into rainfall rates, but contain ...

Abstract: Regulations and public opposition can make siting municipal solid waste landfills difficult. In this paper, spatial-AHP is presented, a method that identifies and ranks potential landfill areas for preliminary site assessment. ...
