Analysis of efficiency of pollution reduction measures in rural basin using MIKE Basin model. Case study: Olšava river basin
Abstract
This paper presents the results of testing the applicability of the MIKE Basin model for simulating the efficiency of scenarios for reducing water pollution. The model has been tested on the Olšava River Basin, which is representative of a typical rural region with a heterogeneous mix of pollution sources with variable topography and land use.
The study proved that the model can be calibrated successfully using even the limited amount of data typically available in rural basins. The scenarios of pollution reduction were based on implementation and intensification of wastewater treatment and land use changes of fields under the risk of soil erosion.
The simulation results proved that the measures proposed for reduction of water pollution can lead to fulfillment of the limits required by the Czech and EU legislation because of the practical applicability of these proposed measures.
