Precipitation, throughfall, stemflow and soil water content were measured, and interception, transpiration, evaporation, runoff, deep percolation and soil water recharge were estimated in the natural Liaotung Oak forestlands in the hill and gully region of the China Loess Plateau. Four stands (south- and north-facing slopes) of 2 forests were studied between May 27, 2006 and October 31, 2007. Hydrological fluxes were calculated using a coupled water and heat flow model called CoupModel. Throughfall, stemflow and soil water content were used to calibrate the model. The simulations indicated that, interception, vegetation, transpiration and soil water evaporation were the main components of water consumption in the 4 stands, accounting for about 90% of the precipitation. The water budget differences among the 4 stands indicate that care is required for properly selecting regrown tree-species
