HEC-HMS based rainfall-runoff model for Punpun river basin

چکیده
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 analyze parameters, preparation LULC, slope maps computation curve number as input into Daily, monthly monsoonal have developed. performance all evaluated statistical indices–coefficient determination (R2), Nash-Sutcliffe efficiency (NSE), percent bias (PBIAS) RMSE-observations standard deviation ratio (RSR). R2 NSE values are greater than 0.75 PBIAS less 10, which shows very good results except daily model, 0.75. Based indices, performs better models.

Comparative Study of HEC-HMS Rainfall-Runoff Model with Different Experimental Methods of Flood Estimation
The most important problem in estimating floods is the lack of sufficient statistics and consequently the lack of evaluation of the appropriate amount of flow. One of the flood estimation methods in these basins is the use of hydrological modeling. In this study, Shahbahram river flood modeling was performed with Nazmkan hydrometric station located in Kohkiluyeh Boyer-Ahmad province with HEC-HM...

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...

Abstract In this study, the predicted monthly temperature and rainfall data from HadCM3 model (base period, ۱۹۷۲-۲۰۰۱) and next period (۲۰۱۱-۲۰۴۰) under A2emission scenario were used to investigate the impacts of climate change on runoff variations in the Kor river basin. HadCM3 model output was downscaled based on a temporal downscaling approach (Change Factor) and spatial downscaling appro...
متن کاملRegional scale flood modeling using NEXRAD rainfall, GIS, and HEC-HMS/RAS: a case study for the San Antonio River Basin Summer 2002 storm event.
This paper develops a framework for regional scale flood modeling that integrates NEXRAD Level III rainfall, GIS, and a hydrological model (HEC-HMS/RAS). The San Antonio River Basin (about 4000 square miles, 10,000 km2) in Central Texas, USA, is the domain of the study because it is a region subject to frequent occurrences of severe flash flooding. A major flood in the summer of 2002 is chosen ...
