Designed to protect against flooding and downstream erosion they store water for a limited period of time, slowly releasing it. These basins are also called “dry ponds,” where no permanent pool of water exists. A retention pond typically always has some water in it, catching runoff from higher elevation areas. The paper describes these and various other methods for collecting water in small reservoirs, as well as practical construction techniques.Text1 digital file (18 p. : ill.)enPHILIPPINESWATER HARVESTINGWATER RESOURCESBASINSWATER QUALITYRUNOFF WATERRESERVOIRSWATER MANAGEMENTFAR EAST ASIAAPPROPRIATE TECHNOLOGYMANUALSManual
