Abstract
Falling of rigid body through air, water, and sediment is investigated
experimentally and theoretically. Two experiments were conducted to drop rigid
cylinders with the density ratio around 1.8 into shallow water (around 13 m
deep) in the Monterey Bay (Exp-1) and into the Naval Postgraduate School’s
swimming pool (Exp-2). During the experiments, we carefully observe cylinder
track and burial depth while simultaneously taking gravity cores (in Exp-1).
After analyzing the gravity cores, we obtain the bottom sediment density and
shear strength profiles. The theoretical work includes the development of 3D
rigid body impact burial prediction model (IMPACT35) which contains three
components: triple coordinate transform, hydrodynamics of falling rigid object in
a single medium (air, water, or s
