Ground water in the plain area of China is recharged mostly with rainfall and to a lesser extent with surface water and nearby ground water. There are several methods for the calculation of recharge of rainfall seepage to ground water. The calculated values using different methods vary due to the accuracy of parameters and calculation methods chosen. A comparative study of methods used to calculate ground‐water recharge by rainfall seepage is made using the water‐balance method and the ground‐water regime analysis method applied to the plain area of China. The accuracy of the ground‐water regime analysis method is superior to that of the water‐balance method. The influential factors (lithology, depth to ground water, precipitation capacity, etc.) of ground‐water recharge by rainfall seepage and the accuracy of these factors are also discussed.
