Abstract

GROUNDWATER CIRCULATION SYSTEMS IN THE AREA OF THE KAMIEŃSKI LAGOON, WESTERN POMERANIAAbstract. The study area is located in the north-western part of the Pomeranian sector of the Mid-Polish Anticlinonum. Factors influencing groundwater circulation systems in the area of the Kamieński Lagoon depend on the geological structure, ascension of brines from Mesozoic strata and the sea water encroachment. The calculation of groundwater flow time along the stream line was carried out for rocks of specified active porosity using a mathematical program developed by K. Burzyński. The groundwater flow model was used for a hydrogeological cross-section line along: Międzywodzie-Kamień Poimorski-Golczewo in the south. The numerical calculations of the flow path front the recharge area to the discharge base level of the present Baltic Sea and the base level in the beginning of the Littorina Sea (7500 years BP) were done to define the groundwater flow time. It has been stated that the current flow time in the fresh groundwater circulation system in the area of the Kamieński Lagoon is nearly twice longer than it was 7500 years ago.
