Abstract The present study was conducted to examine the accuracy and applicability of hydrological models Soil Water Assessment Tool (SWAT) Hydrologic Engineering Center (HEC)- Modeling System (HMS) simulate streamflows. Models combined with ArcGIS interface have been used for in humid tropical Hemavathi catchment (5,427 square kilometer). critical focus streamflow analysis determine efficiency...

Abstract. The changing climate and anthropogenic activities raise the likelihood of damage due to compound flood hazards, triggered by combined occurrence extreme precipitation storm surge during high tides exacerbated sea-level rise (SLR). Risk estimates associated with these event scenarios are expected be significantly higher than derived from a standard evaluation individual hazards. In thi...

A geographic information system ~GIS! based approach is presented for the development of a terrain model based on stream channel representation of the U. S. Army Corps of Engineers Hydrologic Engineering Center’s River Analysis System ~HEC-RAS! hydraulic model. As input, the approach requires a completed HEC-RAS simulation, a digital elevation model ~DEM!, and a GIS representation of the stream...

An operational hydrological ensemble forecasting system based on a meteorological ensemble prediction system (M-EPS) coupled with a hydrological model searches to capture the uncertainties associated with the meteorological prediction to better predict river flows. However, the structure of the hydrological model is also an important source of uncertainty that has to be taken into account. This...

Flood processes become increasingly harmful to communities due factors such as climate change and land use. This study aims evaluate the economic damages of flood events in an area urban basins Lages/SC. Thus, four plans were considered for evaluation: one referring conditions without protective measures three with application elevation structures at different heights, well two scenarios evolut...

This study aims to validate the HEC-HMS model in Karnali river basin of Nepal, while also physically verifying parameters for area. The is a semi-distributed based that requires site-specific information about weather, as well spatial on soil and land use. Using Arc-GIS, HEC-HMS, HEC DSS, hydrological rainfall runoff was developed River at Asaraghat (DHM station 240) period 1998-2005. Calibrati...

Estimation of surface runoff in a watershed based on the rate of received precipitation and quantifying discharge at outlet is important in hydrologic studies. In this study, HEC-HMS hydrological model version 3.4 was used to simulate rainfall-runoff process in Abnama watershed located in south of Iran. To compute infiltration, rainfall excess conversion to runoff and flow routing, methods like...
