Analysis and evaluation of the Geomorphological risks of the Akashat Valley Basin - Western Iraq

Abstract

Abstract:

Akashat Valley is one of the valleys of the Western Iraqi plateau, which is characterized by its surface interrupted by a network of dry valleys with seasonal flows and torrents, which descend with the direction of the surface of the earth towards the Euphrates River in Western Iraq. Through this research, a geomorphological assessment of the Akashat Valley Basin was conducted through the use of modern techniques, to determine the degrees of danger in it after adopting a number of criteria represented by (geological formations, elevation, slope, natural vegetation, rain) and giving a weight to each of them commensurate with the degree of its impact on Levels of risk, in order to build a mathematical model that shows the degrees of risk that have been divided into three levels; The first level represented low-risk lands and occupied the widest area of ​​the valley basin to occupy (45.6%), while the second level represented medium-risk lands and accounted for (45.4%), and the third level included the most dangerous areas to occupy (9%) of the basin area the college. Thus, (91%) of the total area of ​​the basin is suitable for various human activities (human settlement, agricultural activity, transportation methods)
