抄録

The bank protection works using sandbars with boulders which are local riverbed products have been developed and applied in the Jyoganji river, which is one of the most rapid stony rivers in Japan.

These works have two advantages compared to ordinary concrete revetment; 1) making its maintenance easy in the use local riverbed constituent material , 2) extending life-span of banks with existing bank protection works.

This paper shows technical investigation of securing functional maintenance of the bank protection works based on monitoring study and numerical simulation.
