Experimental modelling of tsunamis generated by pyroclastic density currents: the effects of particle size distribution on wave generation

Data set for experimental videos modelling the entrance of a fluidised granular flow into the water.

The data set includes:

• a MATLAB script to calculated theoretical volume and density of a non-fluidised mixture.
• Properties of the fluidised granular flows on the fluidising ramp: volume, density, thickness, flow and impact Froude numbers, kinetic energy of the fluidised flows.
• Properties of the surface elevation: surface elevation at x = 1.6m away from the shoreline, velocity of the leading wave, maximum/minimum amplitudes, potential energy of the generated waves and the energy transfer between the flow and the water column.
• Properties of the underwater gravity current -  displacement, velocity and thickness of the underwater velocity current.
• a MATLAB script to visualise the surface elevation.
