ABSTRACT
The Pingtung Plain, Taiwan, is agriculturally productive and has a generally favourable climate. However, the high annual rainfall is unevenly distributed, causing significant river flows and regular flood events during the period May to October. In the interests of water resource conservation and development, it is therefore desirable to transfer as much as possible of this flood water to the extensive groundwater systems. To this end deep, high-infiltration basins for artificial recharge of the groundwater body have been established in sandy-gravel deposits along the stream bed and flood plain of the Linpien River proximal fan. This paper reports on results from an artificial recharge pilot study in these infiltration basins that was performed over the period 8 October to 16 December 2001. Infiltration rate was found to be ~ 20 m/day. Further investigations, experiments and preliminary numerical modeling are to be carried out at the end of 2002.
