The Analysis of the hydro morphometric properties of the valley Halewat Basin in Anbar Governorate using remote sensing and geographic information systems

Abstract

The valley Halewat Basin is a dry area that ends in the Euphrates. The valley extends over a wavy plateau whose height ranges between (37 m) above sea level near the mouth of the valley and between (132 m) above sea level in the western parts, and thus the land rises gradually as we advance from east to west, the study area contains many Geological formations represented by the third and fourth geological time formations. The determination of the morphological characteristics of Valley Halewat reflects the nature of the influencing geomorphological factors such as the geological composition and structure, surface, climate, soil, and natural vegetation.

The researcher adopted geographic information systems technology and remote sensing data to analyze topographic maps and satellite visuals to reach more accurate data by calculating the formal characteristics of the basin water drainage network. And that the basin drainage network is of the sixth grade. He also indicated that the percentage of drainage density and the frequency of rivers is high due to the high permeability of the rocky structures. This is what was indicated by the rate of discontinuity of the valley floor, and the topography of the basin also indicated that the degree of topography is high, and this indicates that the basin is still in the youth stage of its erosion cycle.
