Abstract

Valley Bastorh Basin is located in the northern part of Iraq in (the northeastern part of the city of Irbil within the administrative border to Shaqlawa distract) between latitudes (15َ 36ْ, 29َ 36ْ) in the north and length (49َ 43ْ, 28َ 44ْ) to the east. The surface area of ​​the basin is 503.9 k.m2. The geographical site of the basin determined by of the Great Zab River from the northwest and Sven and Biermam Mounts from the northeast. Its sources descends from the highlands located between the chains of Sven & Biermam mountains, in this extension, the length of the river in the area would be (98.6) km2 from upstream to downstream.    The study included, the geomorphological hazards of Bastorh valley and its secondary basins. The result was building a model of the geomorphological dangers in the tubs of the studied. All the data on the study had been collected through the preparation of maps and building a data base using (Arc GIS 10.3) program to be the beginning of an integrated database utilized researchers and planners for the development of the region.
