Abstract:

Precise observation of soil water content at multi-scales is the key to understanding the transformation among atmospheric water, soil water, surface water and groundwater, and developing adaptive strategies to the geological hazards associated with it. General observation methods and their principles, advantages, disadvantages and adaptations were presented at multi-scales. Specially, soil water observations at large scale were achieved through soil water inversion models based on the remote-sensing information, e.g. temperature, reflectivity and other parameters developed through the combination of temperature and reflectivity. Methods and techniques used to obtain the information were also presented. Future development of soil water observations was discussed.

Key words: soil water content, isotope tracer, remote sensing, river basin, monitoring
