Changing of precipitation regime and intensification extreme storms in semi-arid regions because climate change requires the use numerical models to forecast outlet hydrographs. In this paper, HEC-HMS software was applied using a loss method curve number CN estimate excess parametric unit hydrograph model compute transformation into direct runoff over watershed. The Muskingum-Cunge routing used...

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 ...

On January 2019, the biggest flood in last decade struck Gowa and Makassar. The claimed enormous number of victims caused severe damage to many buildings; this can be anticipated by Flood Routing. This study aims analyze hydrograph, propagation time, determine inundation model during downstream Bili-Bili reservoir. research was conducted through three phases: delineation watershed using ArcGis ...

In the current study, a novel method is proposed to analyze simultaneous impacts of non-stationarity in hydrological time series and land-use changes urban areas predict future floods probable damage. For this purpose, rainfall frequency analyses were conducted for two periods (first: 1979–2009 second: 1979–2019), results compared. Then, hydrologic modeling catchment was carried out using HEC-H...

land use change is one of the main factors in the process of changing the regime of flood in watersheds. taleghan watershed has been subjected to many land use changes over years, which probably effects on flood characteristics of taleghan river. in present study the effects of land use change on some parameters including peak flow, volume and flood base time, in part of taleghan basin, was inv...

Woodland planting is gaining momentum as a potential method of natural flood management (NFM), due to its ability break up soil and increase infiltration water storage. In this study, 2.2 km2 area in Warwickshire, England, planted with woodland every year from 2006 2012, was sampled using Mini Disk infiltrometer (MDI). Infiltration measurements were taken 10 200 cm away the trees, November 2019...
