Spatial modeling of the torrents risk in Wadi Al-Walaj Basin in Anbar Governorate, using modern geographic techniques

Abstract

The research dealt with the hydrological spatial modeling of torrential risks in the Wadi Al-Walaj Basin in the western plateau in Anbar Governorate, western Iraq, and space visualizations and geographic information systems programs (GIS) were used. A set of indicators was used through the application of a number of hydrological transactions to determine the degree of torrential risk of a basin Wadi Al-Walaj and its secondary basins. The study showed that the region suffers from the risks of torrential flows and its degree of severity varies from one basin to another, as two basins (the middle access and its rivers) appeared under a high-risk torrent level, while the (wasted) basins are below the medium-severity torrents, while the basins (Al-Brim and the eastern walks) are Low risk
