The estimation of degree of influence factors of underflooding on the basis on plot membership is spent. An analysis are produced on the followings factors: exceeding above the level of the river, depth of occurrence the waterproof layer and exploitation of chalk-marly aquiferous horizon. Dependences are got on results treatment of the generalized geological information and these drillholes. The received results allow more exactly localized the areas of underflooding and degree of underflooding, and also operatively to take measures on warning of negative consequences processes of underflooding.
