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...

Abstract Various hydrological models were used in different river basins to simulate the runoff on available rainfall, land use and soil property data. The HEC-HMS model is by several researchers estimate water potential of basin through rainfall-runoff modeling. In this study, a for Punpun has been developed using HEC-HMS. Daily rainfall data from years 2005 2017 development model. ArcGIS anal...

The main scope of this research is evaluation of Soil Conservation Service Procedure in derivation of initial abstraction of precipitation in watershed scale. For this purpose Dalaki watershed which is located in south east of Iran was selected then by using hec-hms and GIS models and a number of observed rainfall runoff events some parameters like CN of watershed ,K and X of Muskingam meth...

Floods have become more severe and frequent as a result of climate change around the world, posing hazard to public safety economic development. This study investigates use distributed hydrological models in flash flood risk management small watershed Hazara, Pakistan, with goal improving Pakistan's early warning lead time. First, HEC-HMS model was built using geographic data river network's st...

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...

these days, all department stores make an effort to provide their clients with valuable products in order to project the best image for them. as a result, clients’ comprehension risk will decrease and they will be more willing to repurchase. having a good image is really important for the department stores because it makes an impression on clients’ comprehension of both quality and risk. consid...

   Hydrological models are simplified representation of the real basin system, which helps to assess basin function in response to different inputs and better understanding of hydrological processes. The HEC-HMS model is one of the most important hydrological models for Flood estimating volumes and discharge in watersheds. In this research, the HEC-HMS hydrologic model was used to simulate the ...
