Outline of Final Research Achievements

The bedforms and sedimentary structures formed by high-speed turbidity currents were studied by flume experiments, simulations, theoretical analyses, and field investigations. Flume experiments showed that the grain size differs between the upstream and downstream slopes of cyclic steps formed by repeated high-speed surging turbidity currents, with the upstream side sometimes being larger and vice versa. For the first time, simulations were able to calculate the grain size distribution of cyclic steps given a mixed grain size. Field investigations provided insight into the paleoenvironment in which cyclic steps form.

Academic Significance and Societal Importance of the Research Achievements

混濁流は地球表層で最も多くの堆積物輸送を担う現象であり,過去の混濁流によって形成された海底扇状地は石油などの良好な貯留岩として注目される.また,混濁流の堆積物は過去の自然災害の規模や頻度を推定する鍵にもなる.本研究により高速の混濁流で形成されるサイクリックステップという地形の粒度分布がわかったので,地層や現地調査での活用が期待される.また,理論解析やシミュレーションの手法も本研究で大きく進展したので,今後の活用が期待される.
