中国东部深层松散沉积含水层严重超采，导致含水层超采，进而导致地面沉降。地质层含有相当厚的粘土，这在抽取地下水和由此产生的沉降之间造成了时间延迟。一个新的计算机代码称为层间排水包已经开发了流行的MODFLOW模型，以解决这一行为。它已被应用于汉沽港的模拟，其结果被用于管理地面沉降问题。
The deep, unconsolidated sedimentary aquifers of eastern China are heavily over-exploited and this causes aquifer compaction1which results in land subsidence. The geological formation contains significant thicknesses of clay which introduces time delays between the extraction of the groundwater and the resulting subsidence. A new computer code called the Interbed Drainage Package has been developed for the popular MODFLOW model to address this behaviour. It has been applied in a simulation of the port of Hangu and the results are being used to manage the land subsidence problem.
