GROUND WATER TABLE CHANGING AND CONTROL IN SHENYANG CITY

The water supply in Shenyang City is mainly depended on groundwater. The groundwater depression was firstly appear in 1960s, and developed to an area of 225.79 km² by 1989. Thanks to some measures such as the limitation to groundwater discharge, the depression has been reducing since 1990s. However, new problems occurred with the water table rising continuously, even to the extent that some underground buildings were flooded. Thus it is necessary to control the water table on a certain height, so as to utilize the groundwater and protect the environmental resources scientifically.
