Abstract:
Flood predictio n is an impor tant no n2eng ineer ing measure for flood contr ol; how ever , small reservo ir s built in t he up2 str eam of many r iver basins can affect the pr edict ion precisio n. In this paper , DHF model was used to pr edict the flood in the Menlou reserv oir . Based on the relative data such as the separated flo ods in the basin, antecedent so il mo isture content, and the relat ionship betw een stor age capacity and area of small r eser voirs, a met ho d w as pro po sed predict flood in co nsideration of the quantitativ e closure of the small reserv oirs, w hich can impro ve the pr edict ion precision g reatly.
