Soil water content (SWC) plays a crucial role in simulating hydrological process, guiding reforestation and controlling soil erosion in mountainous regions. Spatial-temporal variability of SWC increases the difficulty of quantifying SWC pattern in the prediction of soil moisture. Temporal stability analysis of SWC can reduce the labor consuming and simplify the costly field monitoring. This study aimed to evaluate the temporal stability of SWC at hourly, daily and monthly temporal periods and its controlling factors at a hillslope in the Three ...
