Abstract: Water resources utilization has brought prosperous economic growth in many industries and regional developments in Taiwan. In 1995,6. 2 billion tons of groundwater was withdrawn which is about 33% of total water consumption in Taiwan area. However, due to the overdraft of groundwater as compared with the natural recharge of 4 billion tons of groundwater which incurs social problems such as land subsidence, seawater intrusion and flooding. To alleviate these problems, the two master plans entitled the “Groundwater Monitoring Network Plan in Taiwan” and “Land Subsidence Prevention and Reclamation Plan” have activated to protect groundwater resources in Taiwan. The first plan is a17-year project beginning from 1992 to 2008 for the purpose of improving groundwater monitoring in Taiwan area. The first stage (1992 to 1998) of the plan completed 141 hydrogeological survey stations and 332 groundwater monitoring wells at Choshui River Alluvial Fan, northern part of Chianan Plain and Pingtung Plain where serious land subsidence occurred. The second plan has been completed by mid 2000 for preventing further land subsidence by reducing over-pumping of groundwater and by better utilization and management of land use and water resources. A second-stage plan for another five years (2001–2005) has proposed. This paper presents the preliminary results and accomplishments of the above two plans.
