Multidisciplinary integrated studies were performed to develop water/mass exchange assessment methods and evaluate the characteristics of groundwater-surface water interactions in groundwater dependent system. Groundwater-surface water interactions were evaluated through long-term monitoring of groundwater/surface water levels, chemical properties and groundwater discharge ratio in the study area (Upstream of Baekje weir in Geum River). Groundwater levels were significantly affected by surface water levels, however, chemical properties have distinct characteristics depending on depth which indicating that study area consist with separated aquifers. The predicted groundwater flow, water balance, and levels by modeling techniques showed similar trends compare to in situ measuring values.
Additionally, ecological characteristics of subsurface environment was evaluated according to groundwater and surface water interaction changes. Our integrated approaches used in this study could provide as a principle method for research on groundwater surface water interactions in groundwater dependent systems.
