Abstract

In Japan, landslides caused by heavy rains occur every year in various parts of the country, causing damage to human lives, property, and social infrastructure. Why do sediment-related disasters occur in order to reduce the damage caused by sediment-related disasters? Where does it occur? When will it occur? It is important to understand correctly. Therefore, in this paper, we explain the types of sediment-related disasters associated with rainfall, describe the predisposing factors and incentives that cause disasters, and show the mechanism by which sediment-related disasters occur. In addition, we will explain the methods that are being researched or actually used to answer the questions "where does the sediment-related disaster occur?" And "when does it occur?".

日本では毎年のように豪雨による土砂災害が全国各地で発生し，人命，財産，社会基盤への被害が生じている．土砂災害による被害を軽減するためには，土砂災害がなぜ発生するのか？どこで発生するのか？ いつ発生するのか？について正しく理解することが重要である．そこで本稿では，降雨に伴う土砂災害の種類について解説し，災害発生の要因となる素因と誘因について述べると共に，土砂災害が発生するメカニズムについて示す．また，土砂災害が，「どこで発生するのか？」「いつ発生するのか？」という疑問に対する，研究または実際に利用されている手法について解説する．
