ZASTOSOWANIE NUMERYCZNEGO MODELU FILTRACJI W OCENIE WPŁYWU ROBÓT INŻYNIERSKICH NA WODY PODZIEMNE NA PRZYKŁADZIE PLANOWANEGO TUNELU MIĘDZY WYSPAMI WOLIN I UZNAM

Abstract


DESIGN OF NUMERICAL FLOW MODEL FOR EVALUATION OF GEOENGINEERING INVESTMENTS IMPACT ON GROUNDWATER ON THE EXAMPLE OF TUNNEL BETWEEN WOLIN AND UZNAM ISLANDS

Abstract. The investigations were conducted to establish a flow system, groundwater balance within the area surrounding the tunnel between Uznam and Wolin islands using MODFLOW package in configuration of the GROUNDWATER VISTAS 5.0 environment. After model calibration for natural conditions the simulations were done for the three projected options of tunnel location. The most probable variant called K3W1 was analyzed more detailed showing that such a concept could generate some influence on the Wydrzany water intake.
But after simulation in pumping conditions on the average level for the last years it is evidenced that groundwater surface decrease due to the ramp construction doesn’t disrupt normal exploitation of the intake.
