Floating debris obstruction is a problem at many run-of-river structures including navigation locks, hydro-electric and thermal-electric power plants and dam spillways. Previous research suggests that a sound understanding of debris sources, input mechanisms and budgets within the relevant catchment would aid with developing more cost effective debris control methods. Conventional systems such as log-booms and trash racks involve considerable capital cost, can be expensive to maintain and may themselves prevent optimal operation of the structure they protect. This report reviews current debris management technologies that are employed at various run-of-river structures in Europe and the USA. The information reported has been obtained through field visits and from discussions with engineers and plant operators. Relevant published research work on debris control mechanisms, including trash rack design problems, raking equipment and spillway design is also reviewed. The European research centres visited were Deift Hydraulics in the Netherlands, the Hydraulics Laboratory at the Technical University of Munich, Germany, and the Institute of Hydraulics, Hydrology and Glaciology at the Technical University of Zurich, Switzerland. The US field visits were carried out in Western, Eastern, Central, South-Central and Western USA in the Huntington, Vicksburg, St. Louis, Louisville, Portland and San Francisco Corps of Engineers Districts. The control technologies are summarised and state-of-the-art design procedures and best practice management recommendations for debris control outlined for each class of structure that may experience debris-related problems.
