Soil Moisture Measurement for Ecological and Hydrological Watershed-Scale Observatories: A Review
At the watershed scale, soil moisture is the major control for rainfall–runoff response, especially where saturation excess runoff processes dominate. From the ecological point of view, the pools ofExpand
