3D-maaperämallinnus hydrogeologisessa tutkimuksessa : esimerkkinä Kulopalokankaan pohjavesialue Äänekoskella
Äänekosken Energia Oy is planning an artificial groundwater recharge plant in Äänekoski Central Finland. Consulting company Ramboll is in charge of the water intake project that is situated at an important groundwater recharge area, Kulopalokangas. The aim of this study is to collect data from previ...
