The restoration works of natural disaster generally mean restoring the damaged area to its former state. To repair broken roads or rivers as they were before, we need such works as embanking at the head of the slope and removing soil at the foot. But these works can cause other landslides and necessitate huge amount of construction money to cope with a new situation to come. So free from the traditional way of restoration, we thought highly of the economical aspect of the works. The soil removal at the head, the soil embankment at the foot and the groundwater drainage was conducted. The river course was newly designed almost straight. As to the road, alignment was changed instead of the whole restoration. As a result, the construction costs ware reduced significantly compare with the usual restoration works.
