River levees are important structures as a prevention structure of flood. They are affected by a seepage flow, which originates from the rainfall and flood. Most of them were built along with channels, and levee raisings and extensions have been performed after disasters. Therefore, internal structures are not uniform. However, because the flood plain may suffer damage even if levee destruction is local, we have to cope with it by extracting a weak point. The result of investigation shows that about 30 percent of levees is not safe. While advancing a measure on such a weak point, it is necessary to consider the cooperation with prevention-offloods activity, and to raise the degree of safe of river levees.
