摘要

通讯作者:oraby1952@yahoo.com收稿日期:22/10/2021;国家信息文献中心(NIDOC)已决定对西奈中西部独特流域地区的四个流域进行山洪灾害研究。利用最新的地形图，从高程专题层生成了流域、水文、地形和形态构造参数，即;将虚拟高程模型(DEM)转换为适当的确定和分析。实践表明，水文和形态参数在山洪成因中起着重要作用。低坡区与低径流关联和过量泥沙堆积有关。

FLASH FLOOD RISK IN WEST- CENTRAL SINAI, EGYPT

Corresponding author: oraby1952@yahoo.com Received: 22/10/2021; Accepted: 07/12/2021 DOI: 10.21608/egjg.2021.101672.1008 ©2021 National Information and Documentation Center (NIDOC) FOUR drainage basins of the unique watershed regions of west-central Sinai have been decided on to look at the flash flood hazards. Using the latest topographic maps, the drainage basins, the hydrologic, topographic and morpho-tectonic parameters have been generated from the elevation thematic layer namely; the virtual elevation model (DEM) turned into appropriately decided and analyzed. The carried-out technique discovered that the hydrologic and morphometric parameters play essential roles in flash flood contributing factors. The low slopes regions are related to low runoff linked and excessive sediment accumulation.
