The goal of this contribution is to assess the impacts of a global climate change on the Bilina basin hydrological regime. First part of the contribution focussed on the assessment of hydrological changes in the catchment and evaluation of flow conditions for the coal pit flooding. The Bilina basin is located in the northern Bohemia region near the Krusne Hory Mts. All the territory is intensively used as a coal mine area. Primarily eight climatic scenarios were selected on the basis of GCM ECHAM4 and HadCM2 to generate affected meteorological conditions. New data series were created – temperatures and precipitation – as the input for a rainfall-runoff model. The SACRAMENTO SAC-SMA model has been chosen as a tool for the rainfall-runoff simulations. A number of problems caused by the heavy influence of human activities appeared during a calibration. The model has been successfully verified and eight affected flow data series have been simulated. The scenarios have been ordered according to their influence on hydrological regime. The simulated flows have been statistically analysed and compared. The results show that significant shift in flow annual distribution could be expected. |
