At the end of 2021 to early 2022 several areas in Banjar Regency were flooded. This incident had a major impact on surrounding area and became national concern. One causes disaster was high-intensity rainfall which caused water Riam Kiwa River overflow. HEC-HMS software used simulate designed flood discharge. research aims model magnitude discharge with return periods 5, 25, 50, 100 years. Due ...

The paper discusses how the well known USACE HEC models, RAS and HMS, are fully integrated within the decision support system of the Romagna River Basins in order to predict flood effects. The models are fully available from the web and cope with such a variety of problems as rainfall-runoff modeling, river and civil works hydraulics, and the mapping of hydraulic hazard. The paper illustrates t...

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...

Rainfall-runoff simulation is vital for planning and controlling flood control events. Hydrology modeling using Hydrological Engineering Center—Hydrologic Modeling System (HEC-HMS) accepted globally event-based or continuous of the rainfall-runoff operation. Similarly, machine learning a fast-growing discipline that offers numerous alternatives suitable hydrology research’s high demands limitat...

Rainfall runoff modeling is one of the most complex hydrological due to involvement different watershed physical parameters. It essential for analysis response towards received precipitation under influence variables. As it a replica response, Rainfall-Runoff evaluate general characteristics total surface at catchment’s outlet. The main objective this study was prediction rainfall using Hydrolo...

It has become necessary to estimate the quantities of runoff by knowing amount rainfall calculate required water storage in reservoirs and determine likelihood flooding. The present study deals with development a hydrological model named Hydrologic Engineering Center (HEC-HMS), which uses Digital Elevation Models (DEM). This was used means Geospatial Modeling Extension (HEC-GeoHMS) Geographical...

This study presents an evaluation of climate and land-use changes induced impacts on water resources Multan City, Pakistan. Statistical Down Scaling Model (SDSM) Geographical Information System (GIS) are used for change scenario spatial analyses. Hydrologic Engineering Center’s Hydraulic Modeling (HEC-HMS) model is rainfall-runoff simulation. The investigated results show significant in climato...
