Spatial suitability for land uses in the Wadi Tawila basin using RS and GIS.

 basin of Wadi Tawila in Sulaymaniyah governorate in northeastern Iraq within the mountainous area the study area coues of ​​104.58 km2.
Modern technologies such as remote sensing (RS) technology have been used to provide satellite imagery for an area with 11 bands (Land Sat L8 OLI), as well as the digital elevation model (DEM) of the region for topographic topology and hydrology of the region, To benefit from geographic information systems (GIS) programs in topographical, hydrological and engineering analyzes that can be used to search and extract maps and data aimed to reach reaching the goal.
The results showed that the spatial fit according to the natural determinants of the suitable type very large (8.28 km²), very weak type (15.14 km²), spatial suitability according to human determinants of a very suitable type (12.39 km²) and very weak type (8.79 km²).

The spatial fit according to the natural and human determinants of a very suitable type (5.05 km²) by (4.83%) of the basin area and the type is very weak area (8.8 km ²) by (8.41%) of the basin area.
