The land use changes study and precipitation-runoff modelling using HEC-HMS, Case Study: Babolrood basin
Abstract Change in land use pattern influenced hydrological processes in basin and disrupt the normal balance of water flow. In the present research, hydrological parameters change of Babul Rod watershed basin has been that investigated concluded of land use changes in 1988 and 2009. To determine land use changes of Babul Rod watershed basin we has recruited TM satellite images 1988(1367) year ...
متن کاملHydrologic 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 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...
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 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...
