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....
متن کاملInvestigating the Effect of Rainfall Spatial Distribution on Flood in Bakhtiari Dam Basin Using HEC-HMS
The disparate spatial and temporal distribution of rainfall in the country and climate variation sometimes leads to rivers flooding and large flood events, which are remarkable for life and financial losses. Flood control design requires accurate knowledge of the flood generator basin, especially smaller ones, in large basins. Determining the potential of flood generation to specify the...
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 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 کاملOn the Clark Unit Hydrograph Model of HEC-HMS
A mathematically correct form of the linear storage element’s routing equation is specified requiring only a slight modification of the existing HEC-HMS routine. The new formulation, unlike the current version in use, is unconditionally stable as long as the time step and the storage coefficient values are trivially specified as positive numbers.
