A Review on Water Exchange through Interface between Groundwater, Soil Moisture or Atmospheric Water

It is of great significance to quantify water exchange through interface between groundwater, soil moisture or atmospheric water. An overview of advances in water exchange research through interfaces is presented in this paper from three aspects, according to starting point and emphasis of these researches. The summary shows that much development in small scale measurement has been acquired, but most methods have not been solved heterogeneous problem and regional problem successfully. Of all research methods, remote sensing, numerical method and combination method appear to be most promising.
