The analysis of the impact of small retention on water resources in the catchment/ Analiza oddzia?ywania ma?ej retencji na zasoby wodne zlewni

摘要

The aim of this study was to analyse the impact of selected small water retention measures on surface and groundwater level in river basins. The study was limited to the analysis of measures like small water reservoirs, restoration of bogs and reconstruction of drainage systems in the river valleys. A few study cases were described.
