Changes in groundwater recharge and base flow in mountain catchments in Czechia due to changes in snow storages
Kožíšek, Matěj ; Jeníček, Michal (advisor) ; Šípek, Václav (referee)
Changes in groundwater recharge and base flow in mountain catchments in Czechia due to changes in snow storages The diploma thesis deals with the topic of replenishing groundwater reserves due to the melting of snow cover. The main motivation is the importance of the topic for understanding the changes in the hydrological regime caused by decreasing snow cover and small number of research papers on this topic. The aim of the work is to find the relationships between changes in snow cover and groundwater recharge and runoff parameters in the warm part of the year. The main part of the thesis is work with the HBV model. The parameters of underground water reserves and the size of the basic runoff are modeled using climate data and snow water value data from selected mountain basins of the Czech Republic. The Mann-Kendall test and Theil- Sen linear trend is used to evaluate trends in data. The relationships between individual parameters, expressed by Spearmann correlation tests are also examined. The impact of climate change and the associated increase in air temperature was reflected in all runoff and groundwater parameters. Trends were observed at the annual and especially the monthly level. The impact of climate change and the associated increase in air temperature (0.24 to 0.4 řC/decade) was...
