Elaboration of Crrs Models Using Gis and Ga Technology Calibrated at Botonega Catchment


In this paper, the modeling of the catchment water runoff process is created by applying the concept of runoff parameter model or CRRS modeling. The CRRS modeling is made of a relatively small number of structurally arranged elements where each of these elements simulates a certain phase of the catchment process, i.e. a certain phase of gross transformation process and/or effective rain in the corresponding runoff hydrograph. Elements that define the input in the installed CRRS modeling are: hydraulic runoff model where the flow speed component simulates the water translation in the catchment; spatial model of terrain presented through discretization system of catchment elements as an information carrier as to inclination, direction of water flow and the length of passed water runoff on the catchment surface. CRRS modeling consists also of the reservoir elements simulating the effect of catchment retention and the data base of real rainfall events and appertaining measured runoff hydrographs with which the model is being calibrated and consequently improved. The flow diagram of the made CRRS model is presented in Fig. 1. Elements of CRRS models are described through: Concept (hydrologic-hydraulic runoff model) Spatial analysis of parameters (GIS model and runoff simulation) Mathematical runoff model Calibration.
