This paper describes and presents the results of water current studies conducted along the shores of Lakes Superior, Michigan, and Erie. The studies have been made at various harbor locations with the purpose of establishing current magnitudes and patterns within the harbors and in the adjacent coastal areas, and relating the measured currents with the causative forces.

This book assesses the dimensions of our scientific knowledge as it applies to environmental problems in the coastal zone. The volume contains 10 papers that cover different aspects of science, management, and public policy concerning the coastal zone. A consensus is presented on several key issues confronting science for developing a more holistic approach in managing this region's intense human activities and important natural resources.

The objective of this dissertation is to develop numerical models and compare their predictions with data acquired during the DUCK94 experiment in order to improve our physical understanding of the hydrodynamic processes governing the vertical and cross shore distributions of both longshore and cross shore currents over a barred beach. The vertical structure of the mean longshore current is found to be well described by a logarithmic profile and a relationship between bed shear stress and bottom roughness, including the influence of ripples and mega-ripples, was also found. The vertical structure of the mean cross shore current (undertow) is modeled using an eddy viscosity closure scheme to solve for the turbulent shear stress and includes contributions from breaking wave rollers. These models of the vertical profiles of longshore and cross shore mean currents are combined to formulate a quasi three dimensional model to describe the cross shore distribution of the longshore current. This model includes turbulent mixing due to the cross shore advection of mean momentum of the longshore current by the mean cross shore current and contributions from wave rollers.

Coastal Structures are undergoing renewal and innovation to better serve the needs of our society - from environmental co-existence and habitat enhancement to risk management. The CSt07 conference is the fifth in a series that highlight significant progress in the innovation, design and construction of coastal structures. Proceedings of these CSt conferences have yielded milestone works, frequently cited references in the field.This two-volume proceedings contains the final revised version of 178 papers that have been reviewed, selected and discussed at the CSt07 conference. The volume brings to readers a comprehensive range of contributions, covering all aspects of research, design, construction, and maintenance of coastal structures including new up-to-date interesting topics, such as tsunamis and storm surge defences, climate change, piled coastal structures as well as ecological issues, a new addition to the traditional program.
