Abstract

Rock scour evaluation procedures consider both the erosion capacity of flowing water and the resistance offered by the rock mass. The Block Scour Spectrum (BSS) provides a framework for assessing the rock mass resistance according to details of the discontinuity structure. This study introduces a procedure for identifying and extracting rock block structural elements directly from LiDAR point clouds using open source algorithms to support BSS analyses. The approach offers a road map for tackling the details of discrete fracture network generation and block mould computations. As a case study, spillway scour at the Ricobayo Dam in Zamora, Spain is evaluated.
