First, the shape and the length of the natural dam in a narrow channel are cor-related to the width and the total volume of the landslide.Second, the processes of failure of landslide dam by overtopping and breakingdue to slip are observed in detail and classified into three types, namely, 1) whenthe infiltration rate is small, overtopping results, 2) when the infiltration rate isvery large, seepage which appears on the lower part of the downstream face bringscollapse around it and then the collapse proceeds upstream ending by a large failureat the moment the collapse reaches near the blocked water, 3) when infiltrationrate is intermediate, water levels both upstream and inside the dam body rise simul-taneously and a large scale slippage can result.Third, the computer simulation methods to predict the hydrograph of debrisflows due to failure of the dam in the cases 1) and 3) are given, and appear to bein accordance with the experimental results.
