Impacts of thickening unsaturated zone on groundwater recharge in the North China Plain

•Coupling soil water balance and unsaturated zone flow model to estimate recharge.•Dynamic bottom boundary is necessary for unsaturated flow modeling.•Thickening unsaturated zone can result in significant reduction in recharge.•Significant part of percolation can be converted to unsaturated zone sto...
