Literature study Dutch lower shoreface

This report describes an inventory of existing knowledge, field data and models of the Dutch lower shoreface. The Dutch lower shoreface is defined as the area between the upper shoreface (regular and dominant wave action) and the continental shelf (only wave action during storm events). This is roughly the zone between the outer breaker bar (about NAP -8 m) and the NAP -20 m depth contour. This literature review is the first phase of the Coastal Genesis 2.0, Lower Shoreface project in support of Dutch coastal policy, in which the definition of the offshore boundary of the coastal foundation plays an important role. This report gives a system description of the Dutch lower shoreface morphodynamics, defines the state-of-the-art knowledge and outlines further research activities, new field measurements and numerical modelling in particular.
