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....

Rapid and reliable flood information is crucial for minimizing post-event catastrophes in the complex river basins of world. The Chenab River basin one world, facing adverse hydrometeorological conditions with unpredictable hydrologic response. Resultantly, many vicinities along undergo destructive inundation, resulting huge life economic losses. In this study, Hydrologic Engineering Centre–Hyd...

This paper presents a modeling application of surface runoff using the Hydrologic Modelling System (HEC-HMS). A case study was carried out for the Jianghe watershed, a typical semi-arid and sub-humid geo-climatic region in northern China. Two modeling schemes using different descriptive sub-mechanism models provided by HEC-HMS for runoff volume, direct runoff and routing (channel flow) were inv...

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 ...

In the present study, streamflow simulation capacities between Soil and Water Assessment Tool (SWAT) Hydrologic Engineering Centre-Hydrologic Modelling System (HEC-HMS) were compared for Huai Bang Sai (HBS) watershed in northeastern Thailand. During calibration (2007–2010) validation (2011–2014), SWAT model demonstrated a Coefficient of Determination (R2) Nash Sutcliffe Efficiency (NSE) 0.83 0....

Abstract Hydrological modeling is important to provide relevant hydrologic information from limited data. In this study, Hydrologic Modeling System (HEC-HMS) was used simulate the rainfall–runoff relationship for Dabus subbasin of Blue Nile Basin. Daily precipitation and stream flow data 2002 2019 were as key input model, together with soil land use/land cover data, a digital elevation model st...

Abstract This research aims to map flood inundated areas under changing climate in the Boyo watershed of Southern Ethiopia. A semi-distributed physically based Hydrologic Engineering Center-Hydrologic Modeling System (HEC-HMS) and Center-River Analysis (HEC-RAS) were used simulate events maps, respectively, for scenarios. The bias-corrected data four models baseline (1976–2005), mid-term (2041–...

Rainfall runoff modeling is one of the most complex hydrological due to involvement different watershed physical parameters. It essential for analysis response towards received precipitation under influence variables. As it a replica response, Rainfall-Runoff evaluate general characteristics total surface at catchment’s outlet. The main objective this study was prediction rainfall using Hydrolo...

Abstract Frequency of flash floods and droughts in the Mediterranean climate zone is expected to rise coming years due change its climate. The assessment impact at a basin scale essential for developing mitigation adaptation plans. This study analyses variation hydrologic regime small river (the Kalloni Lesvos Island, Greece) by examination possible future scenarios. response was simulated base...

Flooding is one of the most devastating natural disasters occurring annually in the Philippines. A call for a solution for this malady is very challenging as well as crucial to be addressed. Mapping flood hazard is an effective tool in determining the extent and depth of floods associated with hazard level in specified areas that need to be prioritized during flood occurrences. Precedent to the...
