The new technology using sandbars with boulders for bank protection have been developed and applied in the Jyoganji river. These protection works have been found to contribute significantly to the stabilization of riverbed and banks against floods and river environments. On the other hand, it is difficult to use sandbars with boulders in some rivers where there are no boulders. Therefore, we need to develop secondary products useful for a substitution of boulders
This paper presents different kinds of secondary products developed for the bank protection in place of boulders and the results of field investigations monitoring their functional advantages and disadvantages in the Jyoganji river.
