The mechanism of bridge pier scour becomes more complex in the presence of debris accumulation upstream of the pier.While using countermeasures may be effective in reducing scour,their efficacy could be undermined in ...
The rheological behavior of natural slurries consisting of fine-grained,reconstituted debris-flow deposits on pyroclastic terrains having different solid concentrations(ranging from 30 to 42%)has been investigated usi...

A sabo dam has a purpose to block the path of debris flow. However, when overflow occurs, a sabo dam works as a weir, a vertical obstruction, where the fluid must flow over. Many empirical formulas and discharge coeff...

Landslide dams commonly form when mass earth or rock movements reach a river channel and cause a complete or partial blockage of the channel.Intense rainfalls can induce upstream flows along a sloping channel that sig...

The transport of woody debris from urban surfaces, through local urban waterways, to constriction and blockage risk locations is not well understood. Flume trials have identified debris and water- course dimensions as...
Large woody debris and woody vegetation can exert a major influence on channel hydraulics and morphology, particularly in smaller (< 30 m wide) streams. Although debris and vegetation have long been used for channel ...
The movement of debris flows was studied under natural conditions and simple relationships are given to describe the movement. Data collected at the Dongchuan Debris Flow Observation & Research Station in the Jiangjia...
It is of great significance to develop a simple and effective model forecasting storm debris flows. By means of statistical analysis of long term characteristics of precipitation in the mountainous regions to the nor...
This paper presents the experimental results of the deposition outline shapes of sediment water flows on an inclined plane. The experiments simulate the deposition shapes of stony debris flow fans in a flooding plain ...
Based on the fundamental equations for debris now surges, the surface wave profile of debris flow surges with the unchanged crest velocity has been analyzed, and it is compared with the wave proFile for 4 gusts of deb...
