Flow-type landslides Impacting V-shaped Diversions: Physical Modelling

Spatially Varied Flow Profiles in a V-Shaped Side-Channel

Resistance to Flow in a V-Shaped Bottom Channel

Water flow in open channels is always subject to the resistance to flow and energy dissipation. For design purposes, one of the needed variables is the hydraulic resistance coefficient. For this mean, the influence of cross-sectional shape together with secondary flow cells and lateral distribution of true boundary shear stress have not yet been fully explored. This paper surveys the number of ...

Modelling Combined Subaerial-Subaqueous Flow-Like Landslides by Cellular Automata

Macroscopic Cellular Automata characterize a methodological approach for modelling large scale (extended for kilometres) complex acentric phenomena, e.g. surface flows as lava flows, debris flows etc.. This paper concerns the extension of such a method in order to simulate combined subaerial-subaqueous flow-like landslides. The occurrence of heterogeneous interacting processes requires a more p...

Predicting Channel Responses to Flow Diversions

potential to adversely affect the recreational, aesthetic, and ecological resources of mountain streams. The ability to predict channel response to flow diversion can help project designers minimize adverse impacts and design appropriate mitigation measures. Toward this end, we use insights gained from detailed case studies of Lake Fork and Rock Creek – two diverted streams in the Uinta Mountai...

Cellular Automaton for Realistic Modelling of Landslides

A numerical model is developed for the simulation of debris flow in landslides over a complex three dimensional topography. The model is based on a lattice, in which debris can be transferred among nearest neighbors according to established empirical relationships for granular flows. The model is then validated by comparing a simulation with reported field data. Our model is in fact a realistic...
