One of the two main types of aquifer is the unconfinedaquifer.
非承压含水层是两种主要含水层之一。

The water table of the unconfinedaquifer near the coast fluctuates following the tide movement, the aquifer also exchanges water with the sea.
近岸含水层水位随潮水的波动而波动，同时还与海水之间发生着水量交换。

While groundwater flows through an unconfinedaquifer due to heterogeneity, the vertical average saturated hydraulic conductivity is a function of hydraulic head.
