Abstract

An integrated hydrological model has been applied for small rural-urban catchments at the Tisza-Maros confluence using the WateRisk integrated hydrological model system. The aim of the hydrological simulations was to identify the role that the relief plays in the runoff generation process, and to highlight the relationship between the precipitation, runoff and the depression’s water storage of the relief. The overall aim is to support the description of contaminant (phosphorus) transport processes with knowledge about the rainfall-runoff-storage relationship, described with the complex deterministic hydrodynamic model system. To support this aim the rainfall-runoff and the one-dimensional flow routing modules have been used in the model. Results suggest that the depletion of the surface depressions water storage capacity is a non-linear saturation type function of the amount of rainfall falling on the surface. Manning n values of the drainage channel system might also have strong influence on runoff dynamics.
