In this study both data of land use and cover were compared for selected period time it is obvious that urban area significantly increased in Saline River watershed, Arkansas, USA. For hydrologic studies analysis WMS 8.1 program was used to delineate the watershed other processes. further analysis, HEC-HMS analyze results hydrographs peak flows. Results show there impact processes due urbanizat...

Hydrological modeling is a widely used approach for estimating the hydrological response of basin to precipitation. Floods are among most catastrophic natural disasters in small urban watersheds, inflicting loss life, massive property destruction, and severe danger economy. As result, appropriate can be useful tool preventing mitigating such flood hazards. Despite this, flash prediction remains...

Abstract In Iraq, the Diyala River (DR) occasionally experiences both droughts and floods. The DR is supplying amount of water to Tigris at south Baghdad. Estimation runoff from precipitation very important because its impact on decision-making in resources management. conceptual distributed hydrological model was adopted by HEC-HMS, Geo-HMS, GIS software, remote digital elevation models were p...

This research evaluates the applicability of different types hydrological models to simulate discharge behavior scenarios in a northern Moroccan watershed, Oued Laou Watershed (OLW). In this context, an improved understanding runoff mechanisms through modeling OLW can assist hazard risk management and facilitate effective planning water resources. For that end, multitude were used perform very ...
