In recent years, a typhoon and local severe rain occur frequently, and the trees carried out with a mudflow, a landslide, etc. pile up structures, such as a bridge, and give great influence on flood expansion etc.
therefore It is important to estimate the dam woody debris accompanying change of a future local severe rain and so on.
In this analysis, the relation of the precipitation and the woody debris were exxamined based on 15 dam data.
The parameter a, which serves as an absolute term at the time of logarithmic transformation was not based on the precipitation scale of the dam. On the other hand, the relation with a precipitation scale were observed about the parameter b.
