| Abstract |
This study proposes institutional and technical improvements for integrated water resources management with considering the impact
of grounwater use in river-adjacent areas on streamflow. Hydrological connectivity between groundwater and surface water can
significantly affect river ecosystems and downstream stakeholders, particularly during the dry season. However, current management
framework in South Korea treats groundwater and surface water as separate systems, limiting its ability to evaluate and respond
to impacts, such as massive abstractions. This study presents pilot applications of the SWAT-MODFLOW integrated model
and impact-zone mapping techniques. It also emphasizes the need for institutional reform, including harmonization of the
Groundwater and River Acts, establishment of a joint permitting system, and introduction of a total quantity control scheme.
Drawing on international case studies, this study reinterprets the key elements of integrated management in the Korean context
and outlines a transition pathway toward integrated water governance based on scientific modeling, legal reform, and stakeholder
engagement. |
