Book Description
The resilience of San Francisco Bay shore habitats, such as tidal marshes and mudflats, is essential to all who live in the Bay Area. Tidal marshes and tidal flats (also known as mudflats) are key components of the shore habitats, collectively called baylands, which protect billions of dollars of bay-front housing and infrastructure (including neighborhoods, business parks, highways, sewage treatment plants, and landfills). They purify the Bay's water, support endangered wildlife, nurture fisheries, and provide people access to nature within the urban environment. Bay Area residents showed their commitment to restoring these critical habitats when they voted for a property tax to pay for large-scale tidal marsh restoration. However, climate change poses a great threat, because there may not be enough natural sediment supply for tidal marshes and mudflats to gain elevation fast enough to keep pace with sea-level rise. This report analyses current data and climate projections to determine how much natural sediment may be available for tidal marshes and mudflats and how much supplemental sediment may be needed under different future scenarios. These sediment supply and demand estimates are combined with scientific knowledge of natural physical and biological processes to offer a strategy for sediment delivery that will allow these wetlands to survive a changing climate and provide benefits to people and nature for many decades to come. The approach developed in this report may also be useful beyond San Francisco Bay because shoreline protection, flood risk-management, and looming sediment deficits are common issues facing coastal communities around the world.

San Francisco Bay Shoreline Adaptation Atlas

ISBN: 9781950313013
Category :
Languages : en
Pages : 260
Book Description
As the climate continues to change, San Francisco Bay shoreline communities will need to adapt in order to build social and ecological resilience to rising sea levels. Given the complex and varied nature of the Bay shore, a science-based framework is essential to identify effective adaptation strategies that are appropriate for their particular settings and that take advantage of natural processes. This report proposes such a framework--Operational Landscape Units for San Francisco Bay.

Effects of Gravel Morphology on Fine Sediment Accumulation and Survival of Incubating Salmon Eggs
Author: William R. Meehan

ISBN:
Category : Salmon
Languages : en
Pages : 24
Book Description
Rate of fine sediment accumulation and survival of pink salmon eggs were determined for three types of stream gravels. At low stream flows, round gravel accumulated somewhat more sediment than other gravel types, while at higher discharges angular gravel accumulated more sediment. Survival of pink salmon eggs was slightly higher in angular gravel.

Book Description
This broad review is the first to gather comprehensive information on the complete contemporary range of toxicity testing procedures and hazard assessment procedures, which is normally scattered and difficult to find. The two-volume set provides a consistent, template-based approach, linking relevant information on background, theory and practice to each bioassay. Volume 1 covers small-scale toxicity test methods. Includes extensive glossary.
