Theoretical Investigation of the Scouring Dynamics of a River Bottom near an Underwater Crossing

Degtyarev, V. V. / Shlychkov, V. A.

This study is devoted to modeling of currents in channels, and transport of drift during scouring of pipelines. Results obtained from laboratory experiments of flows past a cylinder in a channel with a scour-prone bottom are analyzed. The experiments serve as the factual basis for formulation of a numerical hydrodynamic model. The kinematic regime is analyzed, and the scouring dynamics predicted for investigation of local channel stability in the vicinity of underwater crossings.
