| Outline of Final Research Achievements |
Deterioration of building stone and rock walls due to salt weathering were studied.
Main study areas are Yoshimi Hyaku Ana archaeological site,central Japan,and Orval Abbey in southern Belgium.The TLS and SfM-MVS measurements were carried out to obtain the exfoliated position and volume,although precise accuracy evaluation are necessary.By using these rapid measurement,rock-wall recession of several millimeters or more was detected during the 3-year research period.Seasonal changes of debris production were also observed.The "drying index" were proposed and quantified the relation between salt weathering degree,saline solution supply and dryness degree.
