URBAN WELL-FIELD CAPTURE ZONES DELINEATED USING FLOW STRUCTURE MODELLING

摘要

The town of Domodedovo, Russia, is used here as a case study to test a recently developed flow structure modelling method for the delineation of urban well-field capture zones. A three-dimensional capture zone was determined for the well fields used for the town's water supply. Significant differences in the size of the capture zone intersecting the ground surface and the size of the entire sub-surface capture zone projection were found, suggesting that accurate understanding and prediction of contaminant movement within urban systems cannot ignore the third dimension. The modelling procedure used here performed well.
