USTALENIE ZASOBÓW EKSPLOATACYJNYCH WÓD PODZIEMNYCH DLA NOWEGO UJĘCIA WRZOSY III W TORUNIU

Abstract

SAFE YIELD DETERMINATION FOR THE NEW WRZOSY III WATER INTAKE IN TORUŃAbstract. The Wrzosy III intake is investigated on account of risk of groundwater quality degradation, to change its location. Therefore, a mathematical model was developed for the new location. The research area covers about 15 km2. Groundwater occurs in the Quaternary formations and the aquifer is recharged mainly by precipitation (infiltration recharge module is 109 mm/year). The rest of the inflow comes from lateral flows from beyond the study area and also to some extent from a river. The safe yield on the new Wrzosy III intake can be estimated at 270 m3/h, with expected drawdowns of about 5 m.
