Abstract
<p> There is a sediment inflow disaster that originates from mountain streams in the rain disasters of railways. In the past, there is also an accident that the train runs over a little sand and derails. It takes a lot of time to evaluate the risk of the mountain stream, because there are a huge number of mountain streams along the railway, and those basin are outside the railway sites. And, there is a possibility that variation due to the risk judgment ability of the investigator may occur, because the mountain stream is mixed with various factors such as topography and devastation condition of the river bed or the riverside slope. Therefore, it is the task to create a method that is able to efficiently and effectively evaluate the risk of mountain streams in railways. In this paper, it shows the method for evaluating the risk of the small sediment inflow from the mountain stream of the railways neighborhood by easy investigations. Specifically, it shows a scoring table for evaluating the risk of mountain streams created by statistical analysis based on the data of disaster and non-disaster mountain streams.</p>
