Removal and Release Velocities of Nutrients by Submerged Plants in Flood Control Reservoirs around Juam Lake

Abstract

BACKGROUND: Eutrophication occurs occasionally in flood control reservoirs around Juam lake in summer and early autumn. Lakeside macrophyte which is one of internal pollutants effects on water quality when it is submerged during water surface is rising after rainy season. METHODS AND RESULTS:To improve water the quality of water from water supply source and to establish the management plan of submerged plants in flood control reservoirs around Juam Lake, the removal and release velocities of nutrients by submerged plants in site 1 and 2 were investigated. Removal or release velocity constant (K) of COD by Carex dimorpholepis Steud in column was 0.07~ 0.18 day -1 at 0~4 days after flooding, -0.23~-0.17 day -1 at

“…우리나라의 다목적댐은 산업화와 도시화에 따른 물부족 현상을 해결하기 위하여 주암호, 동복호 및 대청호 등과 같은 인공호수를 만들었다 (Jeong et al, 2011). 우리나라의 온대 몬순 기후 영향으로 여름철에 집중되는 강우를 효율적으로 관리하기 위하여 인공호수내 수위를 여름 홍수기 전에 최대 한 낮추고, 여름 홍수기 이후에 높은 수위를 유지시켜 수자원 이용에 효율성을 가하고 있다 (Han et al, 2011;Kwak et al, 2012).…”
