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 ...

The study aimed to determine the impact of sound land use management to the runoff in Kabuntalan, Maguindanao in Tamontaka river basin. This was done through simulation and the comparison of the three land cover scenarios such as 2015 land cover, 2025 projected land cover and desired land use to determine its difference in terms of runoff. Hydrologic Engineering Center-Hydrologic Modeling Syste...

This study provides a simulation of mercury (Hg) transport in water and sediments the mining-impacted Ambalanga River located Upper Agno Subbasin Philippines. The Hydrologic Engineering Center - Modeling System (HEC-HMS) Water Quality Analysis Simulation Program (WASP) US Environmental Protection Agency (EPA) were coupled to handle both hydrologic modelling total Hg processes, respectively, for...

The amount of rainfall can be used to estimate the runoff that enters a reservoir. Runoff is influenced by land use, and soil type greatly affects will occur. This study discusses development hydrological model with application Hydrologic Engineering Center (HEC-HMS) in Karangmumus watershed using data has been verified field divided into zones based on permeability testing laboratory. With hel...

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....

It has become necessary to estimate the quantities of runoff by knowing amount rainfall calculate required water storage in reservoirs and determine likelihood flooding. The present study deals with development a hydrological model named Hydrologic Engineering Center (HEC-HMS), which uses Digital Elevation Models (DEM). This was used means Geospatial Modeling Extension (HEC-GeoHMS) Geographical...

Sustainable groundwater production from karst aquifers is primarily dictated by its recharge rate. Therefore, it is essential to accurately quantify annual groundwater recharge in order to limit overexploitation and to evaluate artificial methods for groundwater enrichment. Infiltration during erratic flood events in karst basins may substantially contribute to aquifer recharge. However, the co...

Abstract. Floods are among the most destructive natural hazards in world, posing numerous risks to societies and economies globally. Accurately understanding modeling floods driven by extreme rainfall events has long been a challenging task domains of hydrologic science engineering. Unusual catchment responses flooding cause great difficulty predicting variability magnitude floods, as well prop...

arid and semi-arid regions of the world are confronted with limited water resources. a large part of iran is arid and semi-arid and rainfall in arid and semi-arid regions is typically meager, irregular and highly variable. this irregularity affects the hydrological cycle and water resources. investigating the hydrology of the arid and semi arid regions is essential to know this environment and ...

Abha city is distinguished by urbanization, infrastructure, deepening watercourses, and changes in runoff flow which encourage flash floods the urban zones of many villages region. AlMahalah village prone to flooding due its geographic location near outlet convergence streams significant flow. The Geographic Information System (GIS), Remote Sensing (RS), Water Modeling (WMS), Hydrologic Enginee...
