Modling The Morphometric Properties Of The Wadi Al-Saqiyah in North Yemen (Using Geomrphic Informatino Systems)

Abstract

The basin of Wadi al-Saqiyah is one of the basins of seasonal valleys in the northern regions of Yemen, and given the importance of the valley and the availability of the elements of agriculture, and the interest in the possibility of its rehabilitation, this study will present results and proposals based on the study of morphometric characteristics, spatial characteristics, and the characteristics of the water drainage network, as well as identifying some variables Hydrology, using analytical methods that deal with the phenomena of the earth’s surface using data taken from satellite visuals, the digital elevation model (DEM) and topographic maps, using geographic information systems to extract results and establish a morphometric and hydrological database, and the study recommends the need to use geographic information systems in determining the most appropriate sites for the construction of dams And water barriers to feed groundwater, and water retention in proportion to the amount of water, taking into account the future dimension, the increase in the population of the region, and the doubling of their water needs.
