Development of Groundwater Flow Models for the Integrated Management of the Alluvial Aquifer Systems of Dravsko polje and Ptujsko polje, Slovenia

With increasing exploitation of groundwater resources and implementation various activities in their recharge areas, it is vital to conduct a comprehensive assessment aquifers ensure conservation sustainable management. In the present study, we used approach conceptualise identify functioning two connected aquifer systems north-eastern Slovenia: Quaternary porous Dravsko polje Ptujsko polje. The study presents conceptual models both interconnectedness using separate mathematical-numerical with aim ensuring an integrated management these alluvial systems. It also highlights importance understanding connections between such for simulating flow transport different contaminants. To describe entire system, defines its three essential elements: geometry aquifers, by precipitation, other boundary conditions. was defined Sequential Indicator Simulation (SIS) ESRI’s ArcMap software. Next, LIDAR determining surface geometry. hydrogeologic model designed Groundwater Modelling System (GMS) developed AQUAVEO. We MODFLOW 2000 calculation method based on finite difference (FDM). calibrated PEST module, which calibrate hydraulic conductivity heads measured modelled data. Finally, validated Nash–Sutcliffe (NSE) efficiency coefficient. addition, results estimated tool were conductivities determined at pumping sites (pumping tests), each belonging water protection zones that define maximum travel time particles. This performed MODPATH method. paper possibility modelling heterogeneous but interdependent body. connection are most important ones region, system resources. allow better aquifers. Moreover, will be further studies this field, as well
