AbstractThis study was conducted to know the possibility of creating morphometric geo database for Horan valley which is the greatest valley in western desert by using remote sensing and geographic information systems. Digital Elevation Model (DEM) was used to measure the cadastral, morphological or hydrological morphometric properties using the ArcGIS V.10.2 program. These properties considered an important database to make the future planning for dry or wet valleys and rivers basins, which reduce time, expenses and efforts to study the wide area regions. The values of longitudinal section, average of circumference, circularity ratio, circumference compactness factor, elongation factor, form factor, length to width ratio, relief ratio, relative relief, hypsometric integration, basin tissue, the value of rugged, drainage longitudinal density, numerical drainage density, and the Constant of Channel Maintenance, in the Horan valley are 2.562 m km-1, 1307 km, 0.13, 2.77, 0.47, 0.13, 7.3, 2.32 m km-1, 0.64 m km-1, 21.26 km2 m-1, 8 valleys km-1, 0.77, 0.92 km km- 2, 0.61, and 1.08 km2 km-1, respectively.
