Book excerpt: This document is intended for policymakers so they can make informed decisions about upgrading or removing tide gates in an effort to improve conditions for Oregon's native migratory fish and other animals and plants that inhabit estuaries. It has two main sections: The first includes an overview of the technical aspects of tide gates, including non-traditional ones. The second contains findings from a review of scientific literature about upgrading or removing tide gates as well as conclusions from a review of estuary restoration projects involving tide gates. Based on those findings, we're also including recommendations to guide future investments in, and monitoring of, restoration projects associated with tide gates. This document summarizes parts of a 140-page publication, Ecological Effects of Tide Gate Upgrade or Removal: A Literature Review and Knowledge Synthesis, that the Oregon Watershed Enhancement Board (OWEB) funded through a 2016 grant to a team at Oregon State University. That report aimed to help readers understand how tide gates affect water quality and fish. It also sought to help OWEB understand the effectiveness of its investments in estuary habitat restoration projects involving tide gates so it can target future investments. For more information on types of tide gates and their environmental effects, see Oregon Sea Grant's publications Tide Gates in the Pacific Northwest and The Effects of Tide Gates on Estuarine Habitats and Migratory Fish

This book was released on 2009 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dramatic declines in salmon populations in the Pacific Northwest have brought new attention to the importance of estuarine rearing habitats. Levees and tide gates used to convert estuarine wetlands into farmland have reduced available habitat by more than half of historical levels. Recent efforts to restore estuarine habitats include tide gate replacement, though this method has been poorly studied. As a key indicator of salmon habitat suitability, temperature was used to evaluate the effects of tide gate replacement in a tidally influenced freshwater slough in the Lower Columbia River estuary. Three tide gates in the largest slough on Tenasillahe Island were replaced in 2007 with side-hinged aluminum gates. As managed during the data collection periods, the new tide gates did not allow tidal inflow into the slough. The study employed a Before-After, Control-Impact (BACI) approach, collecting data seasonally two years before and after replacement at the impact site and at the control site, a relatively unaltered slough on nearby Welch Island. Randomized Intervention Analysis and Monte Carlo tests revealed no significant difference in slough water temperatures after tide gate replacement, although minimum temperatures dropped up and downstream of the tide gates. Although the new tide gates did not have a significant effect on water temperature, the lower minimum temperatures may have been caused by a slight increase in tidal circulation. This result suggests that slough temperatures would decrease if the tide gates were managed to increase tidal inflow, and thus improve the quality of salmon rearing habitat.

Available in PDF, EPUB and Kindle. Book excerpt: The Pacific Northwest is a global ecological "hotspot" because of its relatively healthy native ecosystems, a high degree of biodiversity, and the number and scope of restoration initiatives that have been undertaken there. Restoring the Pacific Northwest gathers and presents the best examples of state-of-the-art restoration techniques and projects. It is an encyclopedic overview that will be an invaluable reference not just for restorationists and students working in the Pacific Northwest, but for practitioners across North America and around the world.

Download or read book Between the Tides in Washington and Oregon written by Ryan P. Kelly and published by University of Washington Press. This book was released on 2022-12-06 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: A spectacular variety of life flourishes between the ebb and flow of high and low tide. Anemones talk to each other through chemical signaling, clingfish grip rocks and resist the surging tide, and bioluminescent dinoflagellates—single-celled algae—light up disturbances in the shallow water like glowing fingerprints. This guidebook helps readers uncover the hidden workings of the natural world of the shoreline. Richly illustrated and accessibly written, Between the Tides in Washington and Oregon illuminates the scientific forces that shape the diversity of life at each beach and tidepool—perfect for beachgoers who want to know why. Features include • profiles of popular and off-the-beaten-track sites to visit along the Greater Salish Sea, Puget Sound, and Washington and Oregon coasts • the fascinating stories behind both common and less familiar species • a lively introduction to how coastal ecosystems work and why no two beaches are ever alike

This book was released on 2018-11-27 with total page 996 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lock Gates and Other Closures in Hydraulic Projects shares the authors practical experience in design, engineering, management and other relevant aspects with regard to hydraulic gate projects. This valuable reference on the design, construction, operation and maintenance of navigation lock gates, movable closures of weirs, flood barriers, and gates for harbor and shipyard docks provides systematic coverage on all structural types of hydraulic gates, the selection of gate types, and their advantages and disadvantages. The discussion includes the latest views in new domains, such as environmental impact of hydraulic gate projects, sustainability assessments, relation with the issues of global climate change, handling accidents and calamities, and the bases of asset management. Heavily illustrated, this reference provides a generous amount of case studies based on the author’s own and their colleagues’ experiences from recent projects in Europe, America and other continents.

Available in PDF, EPUB and Kindle. Book excerpt: "In the intertidal zone-the space between low and high tide-a rich and complex ecosystem thrives. It's an easily overlooked space, but the porcelain crabs, ochre stars, and other curious species that call this place home provide a window into the hidden workings of the natural world. Drawing on the authority of two leading scientists and the storytelling power of a science writer, this guidebook to the coasts of Washington and Oregon offers general readers a highly-accessible overview of the rich and surprising ways that water and land interact to create seashore ecologies. The authors systematically take readers along the coast, highlighting what makes each location fascinating and unique. (For example, pointing out where to find bioluminescent dinoflagellates, the single-celled algae that light up and trace any disturbance in the shallow water.) At the heart of this richly-illustrated book is a desire to help readers understand the scientific forces that shape the plants, animals, and landscapes at each location; it's the essential guidebook to keep in the car for the reader who wants to know why"--

Download or read book The Waterways of the Pacific Northwest written by Clarence Bagley and published by DigiCat. This book was released on 2022-06-02 with total page 21 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work is a concise history of the Pacific Northwest. The writer, Clarence Bagley, has delivered a brief account of water supply, inland navigation, and many other significant matters concerning the Pacific Northwest, making it a little more than a historical narrative. Bagley focused on presenting this history without making it too wordy and has apparently achieved this objective successfully by making it a text of words fewer than thirty-five hundred. This work isn't a commonly witnessed lengthy and monotonous history but just an accurate, straightforward account of the evolution of the Pacific Northeast. The Pacific Northwest is a geographic region in western North America bounded by its coastal waters of the Pacific Ocean to the west and, loosely, by the Rocky Mountains to the east.
