  • Design Basis for the Living Dike Concept Prepared by SNC-Lavalin Inc
    West Coast Environmental Law Design Basis for the Living Dike Concept Prepared by SNC-Lavalin Inc. 31 July 2018 Document No.: 644868-1000-41EB-0001 Revision: 1 West Coast Environmental Law Design Basis for the Living Dike Concept West Coast Environmental Law Research Foundation and West Coast Environmental Law Association gratefully acknowledge the support of the funders who have made this work possible: © SNC-Lavalin Inc. 2018. All rights reserved. i West Coast Environmental Law Design Basis for the Living Dike Concept EXECUTIVE SUMMARY Background West Coast Environmental Law (WCEL) is leading an initiative to explore the implementation of a coastal flood protection system that also protects and enhances existing and future coastal and aquatic ecosystems. The purpose of this document is to summarize available experience and provide an initial technical basis to define how this objective might be realized. This “Living Dike” concept is intended as a best practice measure to meet this balanced objective in response to rising sea levels in a changing climate. It is well known that coastal wetlands and marshes provide considerable protection against storm surge and related wave effects when hurricanes or severe storms come ashore. Studies have also shown that salt marshes in front of coastal sea dikes can reduce the nearshore wave heights by as much as 40 percent. This reduction of the sea state in front of a dike reduces the required crest elevation and volumes of material in the dike, potentially lowering the total cost of a suitable dike by approximately 30 percent. In most cases, existing investigations and studies consider the relative merits of wetlands and marshes for a more or less static sea level, which may include an allowance for future sea level rise.

CSC, Victoria, Canada BC V8W 3P6 Received 23 December 2002; accepted 27 June 2003 Abstract Two anomalous, gray, silty clay beds are present in ODP cores collected from Saanich Inlet, Vancouver Island, British Columbia, Canada. The beds, which date to about 10,500 14C yr BP (11,000 calendar years BP), contain Tertiary pollen derived from sedimentary rocks found only in the Fraser Lowland, on the mainland of British Columbia and Washington just east of the Strait of Georgia. Abundant illite-muscovite in the sediments supports a Fraser Lowland provenance. The clay beds are probably distal deposits of huge floods that swept through the Fraser Lowland at the end of the Pleistocene. Muddy overflow plumes from these floods crossed the Strait of Georgia and entered Saanich Inlet, where the sediment settled from suspension and blanketed diatom-rich mud on the fiord floor.

  • Five Easy Pieces on the Strait of Georgia – Reflections on the Historical Geography of the North Salish Sea
    FIVE EASY PIECES ON THE STRAIT OF GEORGIA – REFLECTIONS ON THE HISTORICAL GEOGRAPHY OF THE NORTH SALISH SEA by HOWARD MACDONALD STEWART B.A., Simon Fraser University, 1975 M.Sc., York University, 1980 A THESIS SUBMITTED IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY in THE FACULTY OF GRADUATE AND POSTDOCTORAL STUDIES (Geography) THE UNIVERSITY OF BRITISH COLUMBIA (Vancouver) October 2014 © Howard Macdonald Stewart, 2014 Abstract This study presents five parallel, interwoven histories of evolving relations between humans and the rest of nature around the Strait of Georgia or North Salish Sea between the 1850s and the 1980s. Together they comprise a complex but coherent portrait of Canada’s most heavily populated coastal zone. Home to about 10% of Canada’s contemporary population, the region defined by this inland sea has been greatly influenced by its relations with the Strait, which is itself the focus of a number of escalating struggles between stakeholders. This study was motivated by a conviction that understanding this region and the sea at the centre of it, the struggles and their stakeholders, requires understanding of at least these five key elements of the Strait’s modern history. Drawing on a range of archival and secondary sources, the study depicts the Strait in relation to human movement, the Strait as a locus for colonial dispossession of indigenous people, the Strait as a multi-faceted resource mine, the Strait as a valuable waste dump and the Strait as a place for recreation / re-creation. Each of these five dimensions of the Strait’s history was most prominent at a different point in the overall period considered and constantly changing relations among the five narratives are an important focus of the analysis.

  • Fraser River Estuary, British Columbia, Canada, North America Canada's
    Fraser River Estuary, British Columbia, Canada, North America Canada’s Major Stopover for Migrating Birds of the Pacific Flyway The Pacific Flyway is the path of migrating birds stretching from Siberia and Alaska to Central and South America covering over 20 countries and three continents. The Fraser River Estuary is a critical crossroads as millions of the migrating birds converge on the mudflats, marshes and shallow tidal flats of the estuary where the fresh water meets the ocean. Waterfowl and shorebirds from breeding grounds in Siberia, Alaska, Yukon, and other arctic and prairie areas stop to refuel in the Fraser River estuary on their way to wintering grounds in California, Mexico, Central and South America or the South Pacific. Some species spend the winter in the estuary. Pacific Flyway – North America Canada U.S.A.
