Retention potential of beaver dams for surface water storage in the Czech landscape
The Eurasian beaver (Castor fiber) is an important ecosystem engineer that alters the hydrological regime of the landscape through its activities. The aim of this study was to quantify the volume of surface water retained by beaver dams in the Czech landscape and to estimate the potential retention capacity of a selected catchment assuming the maximum predicted extent of beaver colonisation. The main focus of the research was to determine the volume of surface water accumulated behind 150 beaver dams at sites in the Plzeň Region (the Křemelná catchment and ten other selected wetlands) and the inundated area of the associated beaver ponds. GIS analyses based on a combination of precise geodetic data and a digital terrain model were used for the calculations.
Future water demand scenarios to 2050: sectoral analyses and forecasts
This article presents the results of the sub-objective “Scenarios of future water demands for different climate scenarios and individual sec-tors of water use” (DC 1.1). Which is part of TA CR project No. SS02030027 “Water systems and water management in the Czech Republic and climate change conditions (Water Centre)” and is a sub-part of the WP 1 “Prediction of the development of water resources security in the Czech Republic until 2050 in regions depending on climate change”.
