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...

Hydrologic Modeling System (hec-hms):

Many cities have been built along large rivers. The rivers can provide a source of drinking water, act as receiving water for treated effluent, provide navigation for shipping, and other beneficial uses. However, the city must also be protected from flooding due to the close proximity to the river. Hydrologic analysis plays a crucial role in the development of plans for protecting a river city....

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...

Runoff 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 ...
