“…The filtered water from the STF flows into two inflow points (the Boat House and Anapji) in the canal and is discharged into the West Sea. It was reported that various species of phytoplankton communities are living in the coastal water of the West Sea [21]. Since the seawater is collected from an adjacent coastal area in the West Sea, invading phytoplankton communities cause the growth of algal blooms when excess nutrients (eutrophication) are introduced into the canal.…”

Algal blooms have threatened the environmental functions of artificial seawater canals. Generally, water quality in a canal is managed by periodically circulating water from the sea into the canal. However, hydraulic characteristics from the canal design can interrupt the removal of algal blooms by water circulations in the canal. Accordingly, this study analyzed the effect of the hydraulic characteristics on algal blooms in an artificial seawater channel in Central Park, New Songdo City, Korea using a 3-D hydrodynamic model. Nutrients and velocity in stagnant areas in the canal were spatio-temporally measured. Algal bloom locations based on field monitoring mainly corresponded with areas of stagnant water and high vorticity in the z-direction, as determined by the numerical simulations. These results support that high vorticity interrupts the transfer water to the outer area when the canal water is in a stagnant condition. A high value of z-direction vorticity resulted in increased nutrient (total nitrogen (T-N) and total phosphorus (T-P)) availability, and sequentially increases the probability of algal bloom events. In this regard, this study will give a contribution to prevention of algal blooms in the artificial seawater canal. OPEN ACCESSWater 2014, 6 400

Physicochemical water conditions and phytoplankton were investigated at Ggot-jee beach in Anmyondo, summer season of 2011. COD were sometimes recorded higher than 5.0mg/l and SS were always over 40mg/l. DO, pH and salinity were stable generally but low salinity was affected by heavy rainfall. In spite of relatively high concentrations of chlorophyll and phytoplankton standing stocks, discolored water phenomena(green or red tide) had not been occurred. A few dinoflagellate species were dominated in June and July, but general diatoms were dominant species of phytoplankton community in August. Escherichia coli concentrations were higher in August(>400CFU/100ml) than in July but it's not the level of hygienic problem.
