Abstract

Ninety percent of the annual rainfall is concentrated during summer and typhoon seasons in Taiwan. Water shortage periods usually last more than six months. Irrigation water depends entirely on rainfall. Rainwater collection should be a potential alternative water source for supplementing agricultural water needs. This paper attempts to assess the feasibility of rainwater catchment at Yujiing, Tainan County, based on its location, technology, water supply and demand, economy, social and water quality. Simulation analysis is used to determine the variability of water supply reliability with the agricultural rainwater catchment system model. This may also shed some light on the feasibility of constructing agriculture rainwater catchment systems are suitable, based on all aspects considered, for use in Yujiing areas.
