The Delelopment of Basin Multilayer Aquifer

The regime of groundwater in undeveloped heterogenious basin aquifer is characterized by weak and balanced regional and local flow. Effects of anisotropy and heterogenity are hidden in such condition. On the other side, local extraction of ground water in developed aquifer causes strong effects of anisotropy and of heterogenity. Local effects of pumping rate distribution from particular layers, as result of partial closing of well screen, are demonstrated in case of Osijek well field. Hydraulic transmission of such disorder through aquifer can cover the effects of regional character, such as aquifer system recharge. These points are illustrated with some examples of measured and simulated water level behaviour.
