Preparation of a Model for Identifying the Required Points for Structural Organizing of Rivers at the level of Vast Areas (Case Study: Golestan Province)

In this paper, a spatial analysis model is developed that identifies the required points for structural organizing operations at the level of large catchments. For this purpose, initially the nature of the organizing operation in the different structural sections is defined by different spatial constraints, Then the Arcmap software receives required base layers including topographic layer, land use layer, geology and communication routes and presents suggested outputs including the required position to organizing. The advantages of this model areincluding the possibility of defining the new constraints, appropriate processing speed, and providing a step-by-step guide in the software environment. To check the accuracy of the model in predicting the required points for organizing, location matching has been done randomly with field visits and database of studies of river organizing plans in Golestan province. The results of this section show that the proposed model is capable of predicting the required structural organizing points with proper accuracy.
