Topographic data are increasingly available at high resolutions (<10 m) over large spatial extents to support detailed flood inundation modeling and loss estimation analyses required for flood risk management. This paper describes ParBreZo, the parallel implementation of a two-dimensional, Godunovtype, shallow-water code, to address the computational demand of high-resolution flood modeling at ...

Floating freshwater ice is a key component of cold-regions river and lake systems. Ice creates and controls unique aquatic habitats and related biological productivity and diversity. It also poses major challenges (for example, flood threats) and opportunities (for example, transportation) for communities. Changes in freshwater-ice cover have largely mirrored trends in air temperature, with lar...

Dams are one of the most important hydraulic structures. In view unrecoverable damages occurring after a dam failure, analyzing dams’ break is necessary. this study, located in Iran considered. According to adjacent tourist and entertainment zones, breaking could lead severe problems for area bridges downstream river. To investigate issue, numerical FORTRAN code based on 2D finite volume Roe-TV...

surat is a highly developed, thickly populated cosmopolitan character city with full of various activities going on day and night. any natural calamity which causes loss of lives to property and infrastructure along with effects on industrial processes going on has serious impact on economy of the state. therefore, it becomes highly necessary that flood events are studied and analyzed properly ...

The dam-break connected flood hydrograph properties primarily depend on the breach geometry and time for to fully develop. Therefore, prediction of dam’s is essential in studies. To understand impact parameters peak hydrograph, five most common methods are implemented presented study estimate hydrographs using 2-dimensional HEC-RAS model. Ürkmez Dam chosen as case due presence a residential set...

Abstract The impact of climate change may influence on extreme weather conditions and lead to high intensity precipitation, which will huge structures such as dam. Although risk mitigation protection dams from advanced technical expertise have been reviewed regularly, a maximum non-risk guarantee is not achievable, incidents occur due water that usually flows over spillway high-speed discharge ...
