Hydrological and hydrochemical responses of montane peat bogs to climate change
Czech Science Foundation project 22-12837S
Basic info
The project aims to bring new findings on the response of montane peat bogs to climate change.
Using the advanced field and laboratory methods it analyzes the changes in hydrological regime, hydrochemistry, runoff contribution from different zones, and simulates the effects of climate change.

Research goals
The proposed project is focused on the investigation of climate change impacts on the hydrological and biogeochemical processes in the peat bog environment.
The research project aims on the analysis of hydrological processes in headwater zones with the description of flow pathways respecting residence times, as well as runoff formation from different pools (rapid subsurface stormflow, groundwater flow, biomat flow, etc.). The specific targets of this project are as follows:
The effects of climate change and environmental disturbances on the environmental properties and water retention capacity of peatlands will be quantified.
Changes in the hydrological regime and runoff dynamics of montane peat bogs will be described. The role of initial hydrological conditions will be studied.
The main runoff generation mechanisms and flow pathways will be identified based on geochemical analyses (hydrochemistry and stable isotopes). The changes in the shares of key peat bog outflow components – rapid (storm and subsurface) and slow (groundwater) – as the key elements of runoff generation will be evaluated.
The abovementioned knowledge will be utilized for the construction of a new hydrological model describing the behavior of peatlands. The climate change impact on water resources will be estimated.
