Abstract
Downflow baffle breakwaters or floating breakwaters are not as common as "full-depth" breakwaters. As a consequence the scientific work on hydraulic performance and loading is limited and most work dates back to the 1960s and 1970s. Several baffle breakwaters were planned and constructed in Germany in the last decades. Their advantages are reduced costs due to less material required and less impact on sediment transport and water quality. Experiences from different case studies and first results of a desk study on hydraulic performance and hydraulic loading will be described.References
