This course provides a comprehensive overview of sediment impact assessments for channel design and restoration projects. Highlighted, is the importance of sediment impact assessments in determining the potential for sediment deposition or scouring on the channel bed, which can impact the success of the project. Also covered are the types of sediment impact assessments that can be used, ranging from visual techniques for simple projects to numerical models for complex projects, as well as the importance of a bed stability assessment to determine the anticipated channel bed response and the potential for aggradation or degradation. Overall, this course provides a detailed guide for conducting sediment impact assessments, which are critical for successful channel design and restoration projects.
