Digital surface models, land use and rainfall data were used to simulate water areas using Hydrologic Engineering Centres River Analysis System (HEC-RAS) software. Multi-temporal synthetic aperture radar (SAR) was for the detection of flood prone area calibrate HEC-RAS, due lack validation in New Cairo City, Egypt. The thresholding method applied two Sentinel-1 images, one pre- post-flash event...

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–...

In this research a method to calibrate a river hydraulic model (HEC-RAS) using ground-based measurements of an observed flash flood is presented. Applications of the ground truth measurement of flood water depths and flooded areas within a reach of Neka River in Northern of Iran are discussed. The model is calibrated using the Manning's roughness coefficient based on 200-year flood event that t...

Abstract.Pekalongan is one of the areas located in north Java Island. The main problem Pekalongan tidalflooding. This tidal flood worsens when there a high discharge river. For this reason, government builta Coastal Dike and Retention Pond to overcome these problems. concept system create coastaldike that crosses river eliminate effects. retention pond along coastal dike toaccommodate from rive...

Climatic variability, unplanned land use pattern and encroachment into the flood plain are affecting the hydrology of Bagmati river basin of Nepal. In this study, methodology to improve present flood management system with non-structural countermeasures has been elaborated. Study of hydrological condition, basin scale rainfall runoff modeling and inundation analysis is helpful to prepare commun...

Flood is one of the disasters that must be faced in lowlands with poor drainage system, when there high rainfall. Rainfall upstream River can affect water level downstream River. Calculation river discharge and forecast from time arrival flood Help prepare population to face disaster. That method used this lesson a quantitative analysis rainfall planned repatriate. Then, concentration (TC) befo...
