潮州城区由于水库的修建带来浸没问题。经过分析，利用城区渗流场具有的两河间单向渗流的特性，采取悬挂式截渗墙、减压井等工程措施，并布置地下水监测网络。分析蓄水后的监测资料和相关运行记录，可明显看出减压井的工作效果。潮州老城区地下水位情况基本上与设计预测状态相符。城郊个别区域尚存在溢水或承压现象，也做了相应的分析和处理。

Chaozhou City zone is affected by the immersion caused by reservoir project built. According to numerical analysis, mono direct percolation between the two rivers is the characteristic of seepage field of the city zone. Considering this characteristic, some engineering measures such as a suspended cut off wall and relief wells were adopted and the groundwater monitoring system was set up. The monitored data and operation log since impounding are carefully analyzed. The result shows that working effect of the relief wells and the groundwater level of the old city zone are basically close to predictive state. Analysis and disposition are also given to the water overflow or confined phenomena existed in some regions of the suburb area.
