| Abstract | ||
| This research introduces a modern way depending on iteration style between remote sensing techniques and geographic information system .This way summaries in using (GIS) in processing digital elevation model gained by shuttle radar topography mission to derive surface draining nets from it, then calculating morphometric variables associated with it as a substitute for the tradition style used in topograpgic paper maps.This was accomplished by the programmed bundle(Arcgis 9.3 – Global Mapper11 – Erdas 9.1). The study is applied to one of seasonal water basins (Abu Gar basin) located in western plateau in the southern east of Muthana between latitudes( 29 21 18 and 30 42 30 )north and longtitudes (45 34 56 and 46 28 21) east. The research concludes: the importance of integration styled radar data and geographic information system in deriving surface draining water nets time and less costs and efforts .It is a successful substitute for limitation in traditional ways. The research also concludes that Abu Gar basin is hydromorphometric since a number of logartimic-graphic relations are found between draining density and river types that show how much the basin is affected by geology diversity and hydroclimalic situation data which were represented by equations exponential . | ||
