Physical model of landslide generated impulse wave: experimental evidence of the wave-granular flow coupling

Data set from the experimental measurements of a granular flow impacting water and creating a wave The data set includes: Raw control parameters of the experiments : inclination $\theta$, door height opening $h_0$ and chute length $L$ Dry impact characteristics of the granular flow : mass flow rate $q_m$ and thickness $h_i$ Dimensional characteristics of the wave and of the slide deposit: wave maximum amlitude $A_{max}$, time of maximum amplitude $t_{max}$, slide deposit center of mass position $x_g(t_{end})$ and slide deposit front position $x_f(t_{end})$ Characteristics of the granular flow dynamics: horizontal velocity of the granular flow front at early stage $V_f$, granular flow front velocity prior impact with water $U_f$ and the effective immersed volume flow rate $q_{eff}$ Effective immersed slide volume at the time of maximum amplitude $V_{eff}(t_{max})$ All the experiments have been performed at constant water depth $H_0=20$cm.
