Book Description
This report presents results of Phase II of a study performed for the U.S. Army Engineer District, Seattle, to determine the technical feasibility of maintaining a reliable bar or entrance navigation channel into Willapa Bay, Washington. The study was authorized by the Seattle District in cooperation with the Port of Willapa Harbor under a Partnering Agreement. The Phase I study was an intensive effort to understand the physical processes at the study site, collect data, and establish numerical simulation models of the waves and currents at the entrance. Numerous alternatives for creating and maintaining the most reliable entrance channel were also identified and screened. The Phase II study describes the results of ongoing monitoring of the existing natural navigation channel, changes in bathymetry, and refinements to the numerical models. Also included is an application of the monitoring and modeling technology to the entrance channel leading from Willapa Bay to Bay Center, as small fishing harbor. The entrance area of this shallow-draft navigation channel served as a convenient surrogate for improving the predictive technology, as well as advancing understanding of sediment transport processes in the bay and the deep Willapa Bay entrance channel.

Book Description
Beaches, barrier islands and tidal inlets are valuable coastal resources and provide desirable environments that are often densely populated. They are dynamic landforms that change constantly, driven by both normal processes and energetic storms. They behave as one interconnected system and must be understood and managed as such. This book discusses their various morphologic features, as well as the processes that shape them and future challenges due to environmental change. A major focus is placed on the interaction between sandy beaches and tidal inlets, and the sediment exchange among various morphologic features. Balancing these valuable sediment resources while maintaining the natural sediment exchange constitutes a major goal of modern shore protection and coastal management. Illustrated with numerous aerial photographs to demonstrate how beaches and tidal inlets interact, this book provides a valuable reference for graduate students, researchers and professionals working in coastal management and geomorphology.
