Description :
The AA. seek to constrain the probability distribution of splash transport distances on natural hillslopes as a function of hillslope gradient and total precipitation depth. Field experiments were conducted under natural precipitation events to observe splash travel on varying slope gradients of the Miyagase Dam Basin, Kanagawa Prefecture, eastern Japan. Measured splash distances were calibrated to the fully two-dimensional (2D) model of splash transport of Furbish et al. that is based on the assumption that radial splash distances are exponentially distributed. The AA. also compared measured data with several one-dimensional (1D) probability distributions to assess if splash transport distances could be better explained by a heavy-tailed probability distribution rather than an exponential probability distribution. the results are discussed.
