Abstract : This interim report contains a review of methods for managing floating debris that have been tested, and employed, at hydraulic structures in Europe. The information is taken from papers, site observations and discussions with researchers and engineers at three major European hydraulic research centres: Delfi Hydraulics, The Netherlands, The Hydraulics Institute of the Technical University of Munich, Germany, and; the Institute of Hydraulics, Hydrology and Glaciology at the Technical University of Zurich, Switzerland. The interim report is divided into four sections covering different types of structure and the various solutions employed. Chapter one examines run-of-river debris detention and diversion devices. Chapter two discusses debris clogging problems at spillways and assess optimum spillway design with regard to passing debris. Chapter three describes the problem of debris collection at a mn-of-river hydro-electric power station due hydraulics and flow phenomena, and examines the solutions tested to alleviate the problem. Chapter four reviews trashrack design criteria, raking equipment and rack vibration problems. The purpose of the European element of this project, together with an ongoing investigation of debris management at US structures, is the assessment of the major debris management systems that have been employed at hydraulic structures. This will allow the development of a set of well informed best-practice guidelines for floating debris management. (MM)
