The Kabul River, while having its origin in Afghanistan, has a primary tributary, the Konar which originates Pakistan and enters Afghanistan near Barikot-Arandu. River then re-enters Laalpur, making it true transboundary river. catastrophic flood events due to major snowmelt Hindu Kush mountains occur every other year, inundating many urban centers. This study investigates risk under 30 climate...

River renaturation can be an effective management method for restoring a floodplain’s natural capacity and minimizing the effects during high flow periods. A 1D-2D Hydrologic Engineering Center–River Analysis System (HEC-RAS) model, in which flood plain was considered as 2D main channel 1D, used to simulate flooding restored reach of Spree River, Germany. When computing this finite volume diffe...

One of the causes flooding in Makassar City is management water system that not optimal. It necessary to arrange a drainage overcome City. In this study topography on Catchment area analysis, analysis hydrology and hydraulics analysis. Modeling distribution flood performed using HEC-RAS applications. This research was conducted Tallo watershed which consists Upper sub-watershed Mangalarang sub-...

In this study, flood risk areas were determined with Hec-RAS hydraulic model for the Küçük Aksu River in Antalya, Turkey. Firstly, models developed according to different recurrence flow rates and, propagation maps and depth generated. As a result of that was by using 100-year rate, it seen 6.04 ha residential area 33.73 agricultural is submerged. The maximum water level as 11.60 m rate. Then, ...

This paper develops a framework for regional scale flood modeling that integrates NEXRAD Level III rainfall, GIS, and a hydrological model (HEC-HMS/RAS). The San Antonio River Basin (about 4000 square miles, 10,000 km2) in Central Texas, USA, is the domain of the study because it is a region subject to frequent occurrences of severe flash flooding. A major flood in the summer of 2002 is chosen ...

The objective of this study was to assess the performance form-based and process-based models, local-scale reach-scale used examine bank retreat sediment transport in stream restoration. evaluated models were Bank Erosion Hazard Index (BEHI), Assessment for Nonpoint Source Consequences Sediment (BANCS), Stability Toe Model (BSTEM), HEC River Analysis System (HEC-RAS 1D). Model-to-model assessme...

background: the spread of urbanization in floodplains as well as increase of industrial and agricultural activities in river discharges may lead to water pollution by physical, chemical and biological pollutants. one of the major concerns in monitoring the water resources system is indentifying major quality parameters and determining a relationship between physical and chemical parameters. thi...
