Narrative Description of Project

Narrative Description of Project:

The studied rivers are located in the Kordistan & Kermanshah provinces. The aims of study are demarcation of riparian & riverbed of the Razavar, Biar, Salavat Abad, Divandare, Bijar & Talvar Rivers & surveying needed in 35 Km length of the rivers. In this project determined riverbed based on flood discharge-return period of 2, 5, 10, 25, 50, 100 and 200 years and according to the related regulations has been identified riparian based on quality Limitations of the river for protection of water resources. Also, the flood zoning studies determined the areas subject to river or stream flooding, and best planning on flood prevention were offered. Intervals studied of the above rivers in Kurdistan province as follows:

  • Razavar: 8.5 Km
  • Biar: 5 Km
