**4. Conclusions**

The instruments and techniques developed during the long-term monitoring phase of field experimental stations and the establishment phase of indoor experimental laboratory have been specifically described. The methods in the filed observations will enhance the quantitative research about the hydrology process. The new integrated water cycle experimental hall can be used to characterize the water movement among precipitation, vegetation water, surface water, soil water, and groundwater. These characterizations will improve the parameterization in numerical models. In addition, the continued instrumentation development and various techniques are recommended. It is particularly important to develop measurement and predictive techniques for *in situ* or indoor hydrological characteristics in the many instances.
