التحليل المورفومتري لأثنين من أحواض وديان منطقة الحجارة

الملخص EN

The study aims to shed light on the stages of the geomorphological evolution of the basins and valleys of stones area through morphometric study of the origin and upbringing properties and characterization of formal and cadastral and topographic and the dimensions of the docks and the characteristics of the water network Morfumtrella using geographic information systems.

Depending on the digital elevations maps (Dem) satellite (IRS) and topographic maps with the scale (one hundred thousandth) and scale (1/250000) to determine valleys basins that fall within the study area, as well as the use of software (Arc Gis 9.

3) having been focus on the biggest basins in the region of the pelvis No.

study (6) Valley, according to the pelvis number (10) which includes a series of valleys, the most important (Wadi Abu Sadir, Alsjr, Hoatin, Abu Talh, skills).

Where is characterized by the study area the presence of geological formations dating back to Tertiary and of configurations (or Ordmh, Dammam, Venus, gel) as well as the Quaternary sediments where he holds a very small area of the study area.

Most morphometric characteristics also features a study area basins similarity of the results is due to the similarity of climatic, environmental and geological conditions and terrain.
