Impact of Climate Change on a Runoff Formation in Seaside Catchment Area on the Example of the Babica River Catchment

The paper presents the impact of taking into account climate change in the perspective of 2050 on the results of hydrological calculations of characteristic flows in the hydrographically diverse seaside catchment area on the example of the Babica river catchment. A mathematical model of the Babica river catchment was made in the HEC-HMS program. The SCS method was used. The outflow from the basin was analysed for waters with a specified probability of exceedance for the adopted synthetic hietogram for rainfall with a probability of exceeding p = 10 %, p = 1 % and p = 0.2 %. To determine the maximum amount of rainfall in the assumed calculation time, formula of Institute of Meteorology and Water Management for the analysed area was used. The calculations took into account the impact of climate change on the amount of precipitation in the perspective of 2050 - A1B scenario was used.
