Typhoon season provokes temporary water supply challenges throughout Taiwan, but the metropolitan Kaohsiung district of southern Taiwan represents a particularly vulnerable region. Erosive mudstone geology, limited reservoir space, and extreme temporal concentration of rainfall regularly contribute to blockage of major intake pipes and turbidity levels that exceed treatment limits. The Water Resources Agency (WRA) of Taiwan has identified four response scenarios as potential water supply sources for when turbidity severely limits water supply capacity in the metropolitan Kaohsiung district of southern Taiwan.
This thesis evaluates these four response scenarios with respect to a hypothetical severe typhoon. Development of this severe design typhoon applies actual typhoon hydrology and turbidity patterns, as well as historic and potentially catastrophic infrastructure damage, to the water supply system of Kaohsiung and neighboring Tainan. The Dynamic Water Resources Agency Simulation Model (WRASIM-D) provides a mechanism for determining the water supply shortage pattern that the severe design typhoon would yield. Simulation of the same typhoon-ravaged water supply network with individual and paired response scenarios establishes each respective relationship between development capacity and resulting supply. Calculation of the net present value (NPV) for each feasible response scenario identifies one response scenario, a comprehensive improvement program for the Kaoping Weir, as the least-cost feasible response scenario.
