人们担心，气候变化可能会导致荷兰西部低洼地区可耕地下稀薄的淡水囊的致命减少，这是由于微咸渗漏的增加和补给的减少。为了获得初步估计，推导出了一个公式，用于在存在来自很深处的微咸渗透通量的情况下，在一个细长岛屿下的Ghijben-Herzberg透镜的稳定形状，以及一个近似公式，用于估计淡水水体需要多长时间才能适应新的渗透和补给条件。
It is feared that climate change may cause a fatal reduction of thin fresh water pockets under arable land in the low lying western part of The Netherlands, due to an increase of brackish seepage and a decrease of recharge. In order to obtain a first estimate, a formula was derived for the steady shape of a Ghijben–Herzberg lens under an elongated island in the presence of a brackish seepage flux coming from great depth, together with an approximate formula to estimate how long it takes for a fresh water body to adjust to new conditions of seepage and recharge.
