| dc.description.abstract | Drought are frequently occurred at recently years in Taoyuan county, resulted in the fallows, reduces and following restricted water supplies. Therefore the managements of water resource become an important issue especially in the droughts. The usages of water in Taoyuan are investigated firstly, and demands in the north and south Taoyuan are defined separately. The studies focus on the dry season, and make comparative analysis of risks of water shortage.
In this study, the present Taoyuan water supply system are used to evaluate the risk of water shortage as different demands in 2006, 2011 ,2016, and 2021. The results show that the risk of water shortage in south Taoyuan is more critical compared to the north Taoyuan when droughts caused.
Then the study assumed that Panhsin water purification work can support north Taoyuan 300000 CMD after 2011. The deficit rate of water in north Taoyuan area can be effectively controlled and the water shortage condition of south Taoyuan area is slightly improve given the case that agricultural use. On the conditions of Panhsin water purification work only provide 200000 CMD during dry period, north Taoyuan areas still face the water shortage crisis after 2016.
Allowing deficit rate of water in north Taoyuan area are increased to the 10%, 20%, and 30%, the water shortage in south Taoyuan can be slightly improved. However, even the deficit rate of water in north Taoyuan area raise to 30%, the deficit rate of water are still lower compared to the south Taoyuan. | en_US |
