The Analysis Morphometric Watershed Dolabafra Baisn

Abstract

Watershed of Dolabfra is one of the branches of little river in Pishder sub-district, this river flows down into The little river in almost three km far away from south of west of Sultanade village, this basic of river is located in latitude (northern Longitude °36: ¯25:꓿00-°36: ¯29: ꓿00.) (°45: ¯03: ꓿00- east °45: ¯13: ꓿00)eastern longitudes. the main resources of watershed is located the land of Kurdistan Region and board of Pishder sub-district, the source of water providing of this river is situated in a valley of Sharueta village. The main aim of this research includes two parts, the first one is recognition of the characteristics of environments of the area of the research and the second one is to design a special map for each one. Thus, for the purpose of analyzing and using the water resources in the area of the research. In the beginning analysis has been presented for the natural environment of the Basin of Dolabfre and its influence on system of the irrigation, such as (geology, topography, weather and soil) thus, this is through analyzing each of the natural characteristics and direct and indirect effect on flowing river. In the second part, the most important morphometric measures for basin has been carried out, in a way that there is a focus on characteristics of the research (square of the area, shape, height and low, net of the flow of the river). The outcome of the research reveals that natural characteristics of the area of research play main role in the richness of water resources and speed of flow of steam, brook and main river of the basin.
