Reduced water discharge and increased nutrient loads from forest catchments caused water quality degradation in downstream areas such as rivers, dams, wetlands and estuaries. In this study, hydrology and nutrient loading in the deciduous forest had been investigated over a year in order to conserve and manage the aquatic environment of coastal areas in Jeollanam Province. We quantified water discharge and nutrient (total nitrogen and total phosphorus) dynamics. The rainfall from June 28 to 29 (2008) in the deciduous forest catchment on Mt. Baekah resulted in a maximum water discharge (2.7 tons yr?1). The water flow responded quickly to the rainfall due to the steep slope. However, water discharge was low during the snowmelt period. The amount of annual precipitation was 12,519 ton ha?1 yr?1. Summer period (June-August) contributed the largest portion (7,270 ton ha?1) of the total annual precipitation compared to other seasons. The autumn period (September-November), which had a relatively low precipitation, showed the highest flow rate (84%) due to water retention in forest soil. However, the ratio of water discharge to precipitation during the summer period(consisted of heavy rainfall events) was lowest (47%) due to the flood control caused by water retention of the forest soil. The total nitrogen (TN) and total phosphorus (TP) annual input through precipitation were 1,412 kg yr-1 and 23.6 kg yr-1, respectively. Annual output of TN and TP was 198 kg yr-1 and 2.5 kg yr-1 in the deciduous forest catchment ecosystem, respectively. Based on annual nutrient input and output, the annual budget of TN and TP had been 14 kg ha-1 yr-1 and 0.3 kg ha-1 yr-1 in the deciduous forest catchment, respectively. In conclusion, TN and TP had been accumulated in the deciduous forest catchment ecosystem.
