N2 - Experiments were conducted to study burial of cylinders placed on a sandy bed under combined waves and currents. The burial of a finite-length cylinder was determined by local scour around the cylinder and by a more global process associated to the formation and evolution of ripples and sandwaves. Experimental tests covered cylinder Reynolds wave numbers and Keulegan-Carpenter numbers within the ranges 104 ≤ Re ≤ 9.1×10 4 and 2 ≤ KC ≤ 26, respectively. Observations indicate that existing semi-empirical formulae for prediction of equilibrium burial depth for pipelines are not completely suitable for the case of a cylinder having a finite length. In these experiments burial depth shows a strong dependency on both the Shields parameter (θ) and the Keulegan-Carpenter number (KC) combined. Copyright ASCE 2005.
