With the improvement of forest resource, we developed timber check dam which used the large-diameter timbers that supply increased. The construction of timber check dam becomes the structure that construction is possible after not needing a high technique without asking a short term and in all season. In addition, we performed horizontal load test it for timber check dam where approximately 13 years passed from actual construction. The results, we found it satisfying demand performance at the same level at first. From these results, short -term construction is possible, and construction is easy and, in timber check dam which the service of the fixed period of time can expect, the use as the temporary structure between one of the introduction of a concrete check dam is expected.
