Abstract

Catchment runoff modeling is carried out by applying a concept of parametric runoff modeling or CRRS modeling (Conceptual rainfall – Runoff models). The CRRS model provides directives and recommendations for the adequate number of measured inputs (rainfall) and outputs (runoff) as to the most representative
parameter method, which provides the most realistic solutions. Elements that define input in CRRS modeling are: hydraulic runoff models where the flow velocity component simulates water translation in the catchment; spatial model of terrain presented through discretization of catchment elements providing information as to terrain inclination, flow direction and flow path along the catchment surface. The CRRS modeling contains also reservoir elements which simulate the effect of catchment retention. The elaboration of CRRS model is planned on the example of the Botonega catchment for which a satisfactory rainfall and catchment data exists as well as appertaining runoff hydrographs necessary for the calibration and operation of the model.
