| dc.description.abstract | This study was conducted at the No.1Gully of Houyenshan in Sanyi Township, Miaoli County. The research focused on analyzing the characteristics of debris flow movement, including the flow process, geomorphic changes, average velocity, and cross-sectional analysis, by establishing on-site monitoring images. To investigate the debris flow movement process and the characteristics related to rainfall-induced debris flows in the local area, the study compiled rainfall data from various debris flow events between 2016 and 2022. There was a significant correlation between the accumulated effective rainfall (including antecedent rainfall) and the distance of debris flow movement. To further explore the debris flow movement processes and runoff-related characteristics caused by cliff cone accumulation and streambed sediment accumulation at Houyenshan, small-scale indoor experiments were conducted using a flume. The
experiments were carried out with different bed configurations, analyzing the flow patterns of particles, particle movement characteristics, the process of deposit disruption, and the correlations among stream power and various deposit parameters. | en_US |
