| Recently, due to the water shortage by urbanization, industrialization, and climate change, the importance of efficient water resources management is increasing. In particular, when it comes to a planned new town whose development is in progress, the researches on the estimation of the water demand and the water usage patterns are essential for the risk assessment of regional water shortage. In this study, targeting an Youngjong Island, which is in lack of internal water resource owing to the high reliance on external water supply through subbed pipeline and the island characteristics, the amount of water consumption and the water usage pattern in every five years from 2015 to 2030 were estimated in terms of seasonal and hourly basis. At the final objective year 2030, the daily maximum demand of water for living was about 57,000 m3/day, which was approximately 7.4 times higher than that of 2015. Despite of the decrease of the estimated water demand in lpcd (liter per capita day) in 2030, the population increases corresponding to 7.7 times compared with 2015 mainly influenced the increment. The analysis by time-series data at Incheon Airport Region revealed that the water consumption in summer was highest while that of spring was lowest. This was closely related with variation of the number of visitor according to the season change. In addition, the estimation of the water usage pattern in Haneul City, in which most of the population in Youngjong Island is expected to reside, showed that the seasonal water consumption ranked in order of summer, spring, fall, and winter. Further studies are planned to provide the facility invest model that can ensure sustainable and economic water supply under higher water consumption demand. |
