In a period with frequently occurring hydrological extremes, research on areas with a high retention potential is brought into focus. The Šumava Mountains peat bogs are important parts of the landscape in the headwater area of the Otava river basin. The study objective is to describe the variability of discharges and the dynamics of groundwater level changes in various types of peat bogs, and to identify connections between observed physico-chemical water properties. This is assessed by basic statistical methods. The rainfall-runoff process and physico-chemical water properties can be affected by many factors. In this case, strong relations between the observed parameters were identified along with considerable differences in the involvement of various types of peat bog sites in the runoff process. It is evident that the peat bog pattern and its vegetation cover have an essential effect on the hydrological regime and water properties stored in a peat bog.

Significant Phenomenon

The paper summarizes findings about preservation and hydrological conditions of Rokytka Moors situated in the Vydra River headwaters, sw. Czechia. Special attention is paid to the evaluation of their water retention capacity. Due to the significant phenomenon of peat bogs in the study area, the assessment of factors affecting their retention potential represents a component in the discussion on flood protection and measures aimed at increasing runoff in dry periods. The main focus is directed at findings of runoff dynamics dependence on the ground water table in the peatland. Authors thus give attention to the assessment of the Rokytka Moors hydrological function, which represents a typical example of an peat bog in an environment of most of the evaluated parts of Šumava Mts. The research is based on a detailed pedological analysis of the Rokytka Brook catchment, on analysis of an peat bog ground water table time series and on data obtained by monitoring the water stage, discharge respectively, in the profile of the draining stream.

Specific Part

Specific part of wide complex of preventive measures against floods and extreme droughts could be procedures realized in river headstream areas. In order to increase a water retention in headwaters the detailed analysis of peat bogs hydrological function needs to be carried out. Suitable conditions for the research realization at present is related to an existence of several automatic water level gauges and utilization of modern equipment and methods in experimental catchments of the Otava River headstream area (Šumava Mts., southwestern Czechia), representing the core zone of a number of extreme floods in Central Europe. Thorough analyses of extreme runoff phases show more distinct discharge variability of streams draining peat land localities. For the retention potential assessment the detailed measurement of potential accumulation reservoirs, bathymetric mapping of bog pools and the detailed analysis of snow conditions as an important component of a rainfall-runoff process in headwaters is being pursued. The final part of the paper is consisted of suggestions of several unforceable measures implementation that could contribute to reduction of peak flows and to increase of water resources during extreme droughts in future.
