- This study analyzed the spatial distribution characteristics of soil moisture content by forest type in the upper Nakdong River Basin (Yeongju and Bonghwa regions) using the WRF-Hydro hydrological model. The model was constructed based on a 30 m × 30 m regular grid structure, with the soil profile divided into four layers. Land cover-specific parameters such as maximum canopy interception capacity per unit area, canopy height, vegetation density, rooting depth, monthly leaf area index, and monthly stem area index were assigned. Soil parameters, including pore distribution, saturated soil moisture content, and saturated hydraulic conductivity, were calibrated according to regional characteristics. Meteorological input data were derived from the Korea Meteorological Administration and Korea Forest Service weather observation networks, quality-controlled, and spatially interpolated using the inverse distance weighting (IDW) method to generate high-resolution input datasets. Model calibration and validation were conducted using forest flow and streamflow observations from 2021. The simulation results showed distinct spatial and temporal differences in soil moisture distribution among forest types. Coniferous forests generally maintained lower soil moisture contents, whereas broadleaf forests exhibited higher soil moisture levels, with mixed forests demonstrating intermediate characteristics. This study provides fundamental data for analyzing hydrological characteristics by forest type using forest hydrological modeling and is expected to contribute to future research on forest water resource management, forest disaster risk management, and climate change adaptation.
