Soil water controls the basic spatial patterns and processes in earth' s surface system. As an important connection and driving force, it regulates a series of hydrological, ecological, climate and geological processes. In this review paper, we first introduced the advantages and disadvantages of different monitoring approaches (direct measurement, geophysical detection and remote sensing) for static soil water processes (soil water content and matric potential); and then introduced the research progress in measuring (runoff plot, tracer and geophysical detection) and modelling (dynamic wave, water balance and hydrodynamic models) dynamics soil water processes (soil water movement). Based on these, we proposed that the future researches should: 1) integrate the soil water monitoring techniques across spatial scales, 2) enhance the investigation in quantification and reduction of uncertainties in soil water modelling, and 3) coupling soil water processes with carbon and nitrogen transport and transformation. This review paper provides the new perspectives for researches and applications in acquiring high spatio-temporal resolution and accurate soil water data, and in revealing the processes and mechanisms and improving the modelling of soil water, carbon and nitrogen cycles.
