Abstract—Numerous golf courses are being constructed in Korea lately. Along with the construction, many civil complaints are filed against destruction of environment and use of pesticides and fertilizers that are known to significantly affect the water quality of surface water near golf courses. This study analyzes the result of storm water runoff of eutrophic lake watershed in which diffuse pollution sources such as golf resort drainage and agricultural drainage are significant pollution sources. 10 storm water runoff surveys were carried out at Jangcheon Stream and a storm sewer from 2004 to 2007 and water quality was also surveyed weekly from June 2005 to August 2007 in dry seasons as well. Water quality of Flow, TP (Total phosphorus), PO4-P, TN(Total nitrogen), NO3-N, SS, BOD, COD were surveyed. EMCs (Event mean concentrations) of storm water runoff were higher than the mean concentration surveyed for 27 months during dry seasons in both sites. Difference between EMC and the mean concentration during dry seasons was especially large in JM (main stream of the Jangcheon) site which is directly under the influence of Golf resort. Mass-volume curve and evaluation of the first flush effect was completed by utilizing storm runoff surveys.
Index Terms—EMC, golf resort, mass-volume curve, storm water runoff.
