The Significance of Groundwater Table Inclination for Nature-Based Replenishment of Groundwater-Dependent Ecosystems by Managed Aquifer Recharge

Managed aquifer recharge (MAR) is an increasingly popular technique; however, the significance of groundwater flow dynamics rarely examined in detail regarding MAR systems. In general, a high hydraulic gradient not favoured for implementation, as it causes higher water loss and mixing with native groundwater. However, during groundwater-dependent ecosystem (GDE) rehabilitation, these gradient-driven processes can be taken advantage of. The aim this research to test hypothesis by evaluating effect table inclination, topography, other local characteristics on efficiency from perspective GDE restoration. was discharge area simple half-basin based theoretical simulations, using GeoStudio SEEP/W software. Different scenarios were compared analyse level increase infiltrated volumes assess parameters each scenario. results applied close-to-real situation Lake Kondor, Danube-Tisza Interfluve (Hungary), which dried up past decades due decline area. Based results, initial head difference, model length, conductivity are most critical at amount needed increasing mainly influenced thickness unsaturated zone material properties aquifer. findings help better understand light contribute optimising study suggest that, if area, will also corresponding positively effects connected GDEs. This approach serve nature-based solution (NBS) sustain sensitive ecosystems changing climatic conditions.
