Abstract A significant deficiency of most computer models used for stream floodplain analysis is that the locations of structures impacted by floodwaters, such as bridges, roads, and buildings, cannot be effectively compared to the floodplain location. This research presents a straightforward approach for processing output of the HEC-RAS hydraulic model, to enable two- and three dimensional f...

The study aims to evaluate the efficacy of completed concrete canal in urban expansion area city M’sila prevent flood risks river Portem, by performing a hydraulic simulation using 2D program HEC-RAS and geographic information systems (SIG), this research after determining water catchment, extraction morphological characteristics, calculation maximum flow quantity Qmaxm 3/s based on series rain...

There is an immediate need to use available modeling tools quantify environmental flows targets where changing climate and human activity has altered hydroecologically important streamflow regimes. A model performance assessment was undertaken using observed data collected from five nested gauging sites in a mixed land watershed of the central US. An integrated approach used couple The Soil Wat...

Many watersheds in Manokwari are classified as flood-prone areas with a frequency of more than 1 flood per year. Limited rain stations and climate make it difficult to the zoning areas. This study aims utilize remote sensing data hydrodynamic models zone (DAS). The research was conducted Wosi Watershed - Regency West Papua Province. used this is DEMNAS topographic data, Climate Hazards Group In...
