This research have two part, first part is to Collect data and experiment, and consult experiment result to determine rheological parameter.

The influence on the flow region of mudflow due to local trivial stream, rheological parameters and estimated discharge were considered. The strength parameters of soils in upper and middle slope areas were adopted to discuss the difference of mudflow. To understand influence of surface roughness, The sensitivity analysis related to coefficient of laminar flow resistance and manning's n roughness values are also been discussed and compared with sediment concentration by volume.

碩士 === 國立臺灣科技大學 === 營建工程系 === 98 === The digital topography data and estimated mud flow discharge were used to simulate the hazard of Jangmi typhoon. The information about flow rate, deposited depth and submerged region are reported in this study.
This research have two part, first part is to Collect data and experiment, and consult experiment result to determine rheological parameter.
Second part is to analysis Some related survey and test data. Then, the two dimensional numerical program FLO-2D, proposed by O’Brien and Julian, was used to simulate the maokong mudflow case.
