• Abstract:
  The accumulation of large woody debris presents problems for the hydraulics of flow through bridge openings that could lead to increased risks of flooding, local scour, and even bridge failure. The present work is concerned with single-pier debris accumulation at bridge crossings, which is studied with the aid of laboratory experiments and field observations. Laboratory experiments were performed in a systematic study of the effects of velocity and depth on accumulation at a single pier using wooden dowels and twigs as model logs.
