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

<p><strong>Data set for experimental videos modelling the entrance of a fluidised granular flow into the water.</strong></p> <p>The data set includes:</p> <ul> <li>a MATLAB script to calculated theoretical volume and density of a non-fluidised mixture.</li> <li>Properties of the fluidised granular flows on the fluidising ramp: volume, density, thickness, flow and impact Froude numbers,&nbsp;kinetic energy of the fluidised flows.</li> <li>Properties of the surface elevation:&nbsp;surface elevation at x = 1.6m away from the shoreline, velocity of the leading wave,&nbsp;maximum/minimum amplitudes,&nbsp;potential energy of the generated waves and the energy transfer between the flow and the water column.</li> <li>Properties of the underwater gravity current -&nbsp; displacement, velocity and thickness of the underwater velocity current.</li> <li>a MATLAB script to visualise the surface elevation.</li> </ul>
