对沿海地下水含水层的适当管理和环境影响的评估需要准确地估计盐分和淡水的移动。为此，我们比较了研究咸水入侵的两种数值方法。这两种数值方法是约束内插剖面法(CIP)和特征线法(MOC)。用这两种数值方法求解盐分运移方程。将这两种方法应用于承压含水层和非承压含水层的咸水入侵实验，并进行了比较。结果表明，对于这两种情况，CIP方法在保持可接受的数值精度的同时，在计算时间上是优越的。
Proper management and evaluation of environmental effects for coastal groundwater aquifers require accurate estimation of salt and fresh water movement. For this we compare two numerical methods to study saltwater intrusion. The two numerical methods are the CIP (constrained interpolation profile) and the MOC (method of characteristics). The two numerical methods are used to solve the salt transport equation. The two methods are applied and compared to saltwater intrusion experiments for confined and unconfined aquifer case studies. It is found that for both cases, the CIP-method is superior in terms of calculation time while keeping an acceptable numerical accuracy.
