Abstract

The goal of this contribution is to assess the impacts of global climate change on the Biílina basin hydrological regime and the Bilina mine filling. The second part is focussed on flooding of the coal pit under the conditions affected by global warming. There are two approaches how to achieve the objective. The first method uses water from the Bilina river exclusively. The second one takes into considertion an advantage of the existing water resource systém and of large water framework enabling water transfer from the Ohre Rriver to the Bilina River to derive portion of water from the Ohre River. The operating regulations at the Nechranice reservoir had to be adapted to the climate change to improve controlled increase of discharge with regard to the flows transported. A simple water balance model was constructed to simulate a function of the Nechranice reservoir and the coal pit filling. Estimation of the climate change influence on the coal pit filling was performed based on the flooding time changes. The results of flooding simulation show that it is not possible to achieve the coal pit flooding by the Bilina River and it is necessary to transfer water from Ohre River to Bilina River. The climate change could significantly prolong the flooding of the coal pit by about 3 years and the operating regulations at the Nechranice reservoir could be considerably influenced. The impact of climate change could be substantially reduced by an improvement of the controlled increaseof discharge by the Nechranice reservoir.
