O fluxo BI-D aplicado para proteção de poço: o papel da zona de extração na descontaminação subterrânea.

Abstract

The zone of extraction of a well was traced in the Municipality of São Bento in the M.R.H. 89, PB. The test results of production well of C.D.R.M. were utilized. The drawdowns resulting from multiples of pumping rates in Area 4 were used. The results showed that an increase in discharge correspondingly increaseas the capture area. The role of capture zone on descontamination of aquifer is stressed. The effect of an inclined phreatic surface on transport and contribution zones would be of interest in public water supply and in irrigation projects.
