| Outline of Final Research Achievements |
Cosmic-ray soil moisture observing system (COSMOS), a method of measuring cosmic-ray neutrons (φ) near soil surface, was examined to establish an innovative landslide warning system. Although the determination of near-surface soil moisture content (θ) based on φ-value was difficult due to the heterogeneity and uncertainty of water balance in plant communities at sensing slope area, response of φ to soil water index (SWI) and/or θ was observed during the heavy rainfall and continuous drought period. We believe that the COSMOS presented here would be an unique method to monitor near surface soil moisture content of whole slope area if compatible soil moisture model considering the growth of plant communities are proposed.
