This report for project A2020-08 is concerned with safety measures for riverbank erosion and protection against scour. The first part of the report summarizes the fundamentals of erosion in general, in order to provide the context for the main focus of the report, as well as the physical background for the simulation of erosion and for the design of countermeasures. Local scour near structures and riverbank erosion are treated separately. For each of the two the governing mechanisms are discussed, the common approaches for modeling and prediction are briefly touched upon and the common countermeasures are presented. In reviewing the literature, nature-based solutions were found to be of particular interest for the future. While some such solutions are available for protection against scour near structures, most and the ones most widely used concern riverbank erosion. The most widely used nature-based solutions currently in use are collected from the literature in this report. For each support measure the area of application and the most common installation or implementation process are briefly presented. Following this, the results of a series of discussions with experts within Trafikverket are summarized. The suitability of the guidelines currently in use is discussed for different applications. The experiences made in the last years with installation and maintenance for different projects, including the use of naturebased solutions and the problems involved in the use of numerical techniques, are also outlined. The report closes with conclusions drawn and recommendations for future action.
