Evaluation of Debris Flow Impact on Submarine Pipelines: A Methodology

Effect of pipeline surface roughness on peak impact forces caused by hydrodynamic submarine mudflow

“…As a highly destructive and sporadic load, submarine landslides, debris flows and mudflows, which are characterized by hydrodynamics, have caused great damage to submarine pipelines [1][2][3][4]; hence, these have become a research focus in recent years [5][6][7][8][9][10][11]. In terms of physical simulation, based on 1g single-phase (anhydrous environment) particle flow experiments [12][13][14], 1g flume experiment [15][16], rotating flume experiment [17] and Ng centrifugal model experiments [18], the researches on the interaction between submarine landslides and pipeline were carried out, the related laws were deeply explored, and reliable methods for assessing impact forces under simple working conditions were established.…”
