Modification and Training of Khabr's River of Baft, using HEC-RAS model

Note that the border village’s expansion of Khabr’s River of Baft located in Kerman and incursion into river’s sides in recent years, flood damages to rural areas, agricultural Lands and its around gardens a lot. Bed’s slope, existence of river’s meanders, high velocity of water flow, incursion by agricultures into river’s sides induced under cutting and degradation of farms, and in some area caused of overflow and entrance of water into the marginal farms and gardens. The river’s behavior is simulated by HEC-RAS model and succeeding results used for presenting of Khabr river’s flood control scheme. Among the different methods for modification and training of river’s path, At first, building of training wall at river’s watersides was investigated. The model which yields such results, increases foundation depth and water scour depth causing cost will increase. Results of model illustrates that using of two parallel methods i.e. waterside walls and successive dams was investigated in order to decrease the costs. Constructing these Dams results in the total cost is significantly decreased. In order to evaluate the performance of these constructions, specifications of proposed constructions was imported to HEC-RAS model, and constructions’ influence on improvement of conditions was evaluated and confirmed by means of further execution of the model.
