Usually this is understanding as stopping and dam up waters in water-courses and accumulation her in water reservoirs.

Ac-tivities in range of small retention serve to improvement of water balance in ca-tchments across enlarging of supplies discretionary waters. Determine also impor-tant element of protection of waters quality. Indicatory value of small water retention water are 6246 m3/km2, in this in marshlands stored water equal 2184 m3/km2. In plans to 2015 foresees on investigated areas of forest ...
