In the temporary coffering method of the river works, large sandbags have been used from the perspective of Workability and Economics. But, during flooding, the large sandbag often can become problematic impact on construction sites and their hinterlands, which becomes a problem. Usually, Large sandbags are made by concatenating the under the weight of their own and ensure the stability of the structure, but large sandbags are separated each other. So, they are prone to unstable by flooding. In this paper, we reports a case study; the continuous collapsible wire mesh frame with non-woven fabric liner of the unitedness was applied to the temporary coffering method in the flowing river for the first time and this method played the role of riverwall without damaging by the reinforcement for the flow by the typhoon. Then, by the analysis of flow based on the result, we confirmed that it has the ability to withstand the current velocity of flooding.
