Book Description
Because large parts of The Netherlands lie below sea level and are largely protected from flooding by a narrow strip of sandy beaches and dunes, optimal management of this coastal strip is of vital importance. This work extends the existing knowledge of dune erosion during storm surges as it occurs along the Dutch coast. Among the areas discussed are: a large scale erosion experiment designed to improve insight into near dune hydrodynamics, sediment transport and interaction between dune face and swash zone; detailed modeling to study dune erosion physics, validated against measurements, and a morphodynamic dune erosion model applied in a variety of dune erosion conditions. This publication represents a valuable contribution to an improved understanding of dune erosion, an increasingly important area of study with regard to climate change and rising sea levels.

Book Description
This report examines the feasibility of accounting for the processes of erosion and overwash in the determination of coastal high-hazard flood zones, or V-zones. Included in the report are discussions of the merits and limitations of existing theoretical, empirical, and parameterized models for predicting beach profile change and dune erosion. Also included are discussions of the variabil ity found in measured storm changes and an extensive review of the overwash literature. Of the models evaluated, two dune erosion models were found to produce reasonable dune erosion estimates. One model (Kriebel 1982) is based on the assumption of uniform energy dissipation in the surf zone and the concept of an equilibrium profile shape which responds to a rising water level by shifting upward and landward. The other model (Vellinga 1983) was developed from an extensive series of large scale physical model tests. Both of these models were evaluated using 14 profiles from four different storm events and found to produce comparable results. Of the two, the Kriebel model was found to be less demanding in terms of required input information (prestorm profile shape, storm surge height, etc.) and therefore easier to consistently apply. Used properly and in combination with historical data (aerial photographs and field surveys) and engineering judgment, these models can provide a consistent mechanism for the establishment of V-zones in areas prone to storm erosion.

Book Description
This proceedings contains papers presented at the 31st International Conference on Coastal Engineering, which has held in Hamburg, Germany (31 August - 5 September 2008). The proceeding is divided into five parts: Waves; Long Waves, Nearshore Currents, and Swash; Sediment Transport and Morphology; Coastal Management, Environment, and Risk; and Coastal Structures. The papers cover a broad range of topics including theory, numerical and physical modeling, field measurements, case studies, design, and management. Coastal Engineering 2008 provides coastal engineers, scientists, and planners, with state-of-the-art information on coastal engineering and coastal processes.
