Simulation of Rainfall-Runoff Process Using Green-Ampt Method and HEC-HMS Model (Case Study: Abnama Watershed, Iran)
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...
متن کاملRunoff characteristics and application of HEC-HMS for modelling stormflow hydrograph in an oil palm catchment.
Rainfall-runoff processes in a small oil palm catchment (8.2 ha) in Johor, Malaysia were examined. Storm hydrographs show rapid responses to rainfall with a short time to peak. The estimated initial hydrologic loss for the oil palm catchment is 5 mm. Despite the low initial loss, the catchment exhibits a high proportion of baseflow, approximately 54% of the total runoff. On an event basis, the ...
متن کاملGis-based Hydrological Modeling: a Comparative Study of Hec-hms and the Xinanjiang Model
The last few years have witnessed an enormous study in the area of integrated hydrological modeling with GIS application. In this research, attempt was made to critically look at the application of HEC-GeoHMS which is an extension of ArcView in HEC-HMS; an HEC package which is a new generation of software being developed for rainfall-runoff simulation. The main role of HEC-GeoHMS is to formulat...
متن کاملUse of HEC-RAS and HEC-HMS models with ArcView for hydrologic risk management
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...
متن کاملApplication of the HEC-HMS model for runoff simulation in a tropical catchment
Hydrologic simulation employing computer models has advanced rapidly and computerized models have become essential tools for understanding human influences on river flows and designing ecologically sustainable water management approaches. The HEC-HMS is a reliable model developed by the US Army Corps of Engineers that could be used for many hydrological simulations. This model is not calibrated...
