Abstract:
In this paper the method of optimization of the channel route and bed slope of a water conveyance channel by means of Geographic Information System (GIS) is described. The work is a part of the Flood Spreading and Groundwater Management Project of Chikhab River; a river located in the area of Dehloran, South-West of IRAN.First based on the topographic maps (scale 1/10000), the Digital Evaluation Model (DEM) of the channel route was developed. Then, considering the limitation of the height of the water intake, the bed longitudinal slope and the location of the required hydraulic structures, different variants of the channel route were identified and studied. On this basis, 12 variants of the channel route and project line at 4 different slopes (a total of 48 variants) were investigated.The best channel route was determined by minimizing the volume of the earth-work (cut and fill) and by considering the variety and total number of the required hydraulic structures within the channel route. Finally a 19 kilometers earth channel was proposed as the best variant. This paper indicates the capabilities of GIS in optimization of the design parameters in this type of hydraulic engineering projects
