Changes in rainfall-runoff regime and biogeochemistry in headwater areas
 Fraindová, Kateřina
Headwater areas are a very important current or potential drinking water source. Their ecological value for the whole ecosystem is equally important. Headwater areas are sites with minimal anthropogenic intervention and usually the least polluted water sources. Changes in climate and rainfall-runoff (R-R) regime together with water quality in these areas affect the status and availability of water further downstream significantly. It is also one of the most sensitive areas and is an early indicator of ongoing changes. This thesis focuses on the main issues that are already ongoing and are affecting the availability of drinking water significantly. Some of these are trends in R-R regime in the context of the climate change and glacier retreat in headwater areas. As a very good example of a mid-latitude river with a complex rainfall-runoff regime, where a large impact of regional climate warming and glacier retreat are strongly manifested, The Athabasca River Basin was selected for this study. Related to this issue is the river water quality, which is influenced by changes in both temperature and R-R regime, together with the increasing occurrence of extreme hydrometeorological situations such as droughts and floods. The effects of land cover on water quality are also analysed, along with consideration of...
