Integration of a Shallow Soda Lake into the Groundwater Flow System by Using Hydraulic Evaluation and Environmental Tracers

Lake Velence is a shallow soda lake whose water level and quality show severely deteriorating tendency in recent years. Until recently, the groundwater component lake’s budget has not been taken into consideration. To integrate flow system at regional scale, methods of “basin hydraulics” were applied. In addition, 17 samples collected for ?2H ?18O, ?U, 226Ra 222Rn activity measurements to use these parameters as environmental tracers contribution. Groundwater mapping revealed that recharges Hills local elevations south lake, whereas discharge occurs by shoreline along surface watercourses. The results indicated point systems known be more sensitive climate changes anthropogenic activities (e.g., contamination, overexploitation). have similar uranium concentrations serving another sign inflow lake. Therefore, it necessary consider both management its vulnerability regarding short-term catchment area.
