|Abstract:||This Coastal and Hydraulics Engineering special report is a general overview of the current state of nearshore berm placement research. The report describes current design guidance for nearshore berm placement, as well as the major findings of existing numerical and physical modeling studies. Field experiments are also summarized. Numerical and physical models are important as they help to illustrate in greater detail the morphological evolution and hydrodynamic effects the berm has on the surrounding area. Physical models allow for two- and three-dimensional illustration of these concepts. Field studies show that onshore migration of active berms occurs and the tendency of nearshore berms to act as a submerged breakwater. Although many field and modeling studies exist to assess the morphologic and sedimentologic evolution of berms, a need for more detailed understanding of the processes associated with these types of nourishments still exists. More data to predict where material is going, how the existing adjacent morphologic features respond to the placement, and how long the material will remain in place (or its intended location) are necessary to answer stakeholder questions for these types of placements.|
