MORPHOMETRIC ANALYSIS USING GEO-INFORMATION TECHNIQUES FOR BASTORA BASIN NORTH EAST OF ERBILCITY IRAQI KURDISTAN REGION

The current study aims to conduct a detailed morphometric investigation of the Bastora basin watersheds in northeastern section Erbil, Iraq. region is situated between longitudes 44o 10' 19" and 27' 33" east latitudes 36o 19' 36" 15' 17" north. present research attempts detail analysis To meet goals this study, areas basins are 236.4 Km2. Geo-information (Remote sensing GIS) techniques were utilized determine analyze characteristics terms linear, aerial, relief aspects. Several tools ArcGIS 10.8 program used prepare produce maps, evaluate various parameter features, enforce specification hydrology tool. An area was covered by six-order drainage sub-basin with total (587) streams (418.24 km) stream length. Just mean bifurcation ratio (3.62). sixth order sinuosity index value (1.4). results (1.77 km-1 for density 6.00 texture. circulation elongation (0.31). extended morphology, low runoff discharge, high subsurface permeability imply these characteristics. river can be thought as average stage balance erosion sediment deposition. hydro-morphometric very helpful guide choosing location type dam.
