groundwater dynamics

Effects of sea tide should be considered in modeling groundwater dynamics and associated contaminant transport in coastal aquifers, which may result in significant increase of computing time especially for variable-density contaminants, and superior numerical performance of the model is required.

模拟沿海地区地下水及污染物的输移需要考虑海洋潮汐的影响，对于变密度污染物，考虑潮汐的影响会大大增加模型计算量，模拟此类问题要求模型具备优良的计算效果。

It points out the ap-plication prospect and limitations of these models-It presents several ways of coupling application of the time sequence analysis model with the groundwater dynamics model.

指出这类模型的应用前景和局限性，提出了时间序列分析模型与地下水动力学模型耦合应用的几种途径。
