Water balance is typically closed for the topographic catchments in the general catchment hydrology. Due to the special characteristics of Karst, e.g., the connected conduit system cross the topographic catchment boundary that induces inter-catchment groundwater flow, this alters the effective size of a catchment and affects the total water balance. Quantifying inter-catchment groundwater flow is essential for hydrological modeling beyond catchment scale and helps water resources management.
The aim of this work is testing a newly proposed approach that addresses inter-catchment groundwater flow at Karst regions. Three different scenarios will be compared and evaluated to verify the new approach so that the possibility of transfering this approach for a larger scale can be discussed. The hydrological models and detailed procedure are already available.
