The Characteristics of Water Usage in Jeju Golf Courses
This study is to analyze the characteristics of golf course water usage using groundwater and rainwater data obtained from 17 golf courses in Jeju Island during 2007~2009. The groundwater usages were 246,275 ㎥/year, 213,062 ㎥/year, 155,235 ㎥/year, and 126,666 ㎥/year in the west, south, east, and north regions, respectively. Monthly rate of the amount of groundwater usage to the amount of permission was 29.5%. The rainfall usages were 386,591 ㎥/year, 326,464 ㎥/year, 251,248 ㎥/year, and 232,061 ㎥/year in the south, west, east, and north regions, respectively. Monthly rate of rainwater usage to the amount of water retention of golf courses was 19.6%. The average annual water usage in the 17 golf courses was 499,377 ㎥/year. From the average usage, it was found that the rainwater usage (305,126 ㎥/year) was 1.6 times higher than that of groundwater (194,251 ㎥/year). That means the annual average rainwater usage to the entire water usage was 61.1%, which was above the criteria of 40%.
