Abstract
A system dynamics model was built for the TanHsui watershed. The model was used to evaluate sustainability of use of water resources. Study areas include water supply systems of Taipei, PanHsin and ShihMen. The stream flow record between 1991 and 1999 and release water from the Feitsui and ShihMen Reservoirs are used for the model verification. This study adopts two indexes, Shortage Index, SI and Agriculture Supply Index, ASI, to find the maximum water supply of water resource system. It is defined as carrying capacity. Furthermore, a Sustainable Development Indicator (SDI) is established to evaluate sustainability of use of water resource in TanHsui watershed.
The results show that the SDI in all study areas is equal to 1, and it means the water supply system is sustainable. However, there is a difference between Taipei, PanHsin and ShihMen about water supply. In Taipei, it has a large surplus of water, but in PanHsin the water supply faces the stress of deficient water. According to Water Act, domestic use has the top priority of water usage and agricultural use has the second. Therefore the water supply meets domestic water use firstly in ShihMen area in this research.
This research also considers the influence of climate change; it assumes that water demand is equal to that in 2025 when climate change happens. Besides, it considers the government’s policies in the future. The great part of results show that the water supply system under climate change is sustainable, but the carrying capacity shows a descendent trend.
