Modelling future hydrological pattern in a Bohemian Forest headwater catchment

Original language description

This study focuses on estimation of the impacts of anticipated global climate change on water balance in forested headwater catchment. The investigated catchment is located in Bohemian Forest National Park in the southern part of the Czech Republic. We calculated nine future water balance scenarios for periods of 2021–2050 and 2071–2100. We used data from following models: CNRM-CM5_ALADIN53, EC-EARTH_RACMO22E, EC-EARTH_RCA4, MPI-ESM-LR_CCLM4-8-17 with 3 emission scenarios (Representative Concentration Pathways RCP2.6, 4.5, 8.5). Corrected regional climate model daily data were used in combination with hydrological model Brook90. The scenarios projected an increase of mean annual temperature of 1.1°C (RCP4.5) and 1.4°C (RCP8.5, 2021–2050) and 2.3°C (RCP4.5) and 4.2°C (RCP8.5, 2071–2100) and increase in mean annual precipitation amount of 11percent (RCP 4.5) and 15percent (RCP 8.5, 2021–2050) and 15percent (RCP 4.5) and 20percent (RCP8.5, 2071–2100). It would result in mean annual runoff increase of 9percent (RCP4.5) and 14percent (RCP8.5, 2021–2050) and 12percent (RCP4.5) and 16percent (RCP8.5, 2071–2100). The annual runoff cycle is projected to change significantly especially in the period of 2071–2100, when a large winter runoff increase and spring runoff maxima decrease is expected. “Pessimistic” RCP8.5 scenarios expect even no spring runoff maxima from snowmelt and project a shift of runoff maxima to December.
