Book excerpt: Sediment deposition occurs in the lower reaches of the concrete-lined Corte Madera Creek flood control channel because the elevation of the channel bottom is below sea level. These sediment deposits, combined with the presence of tube worms and barnacles on the channel walls, reduce the flood-carrying capacity of the channel. The upstream portion of the original flood control project was not completed and flood flows above 3,000 cfs are not contained in the natural channel upstream. Thus, there is reduced flow competency to carry the coarse sediment load delivered by flood flows. With annual maintenance and upstream containment of breakout flows, most of the sediment deposited in the concrete channel from seasonal antecedent flow can be washed out by the time the flood peak occurs. An HEC-6 numerical sedimentation model study was conducted to evaluate several alternative plans to provide flood containment and sediment storage while also maintaining the natural characteristics of the upstream channel.

Available in PDF, EPUB and Kindle. Book excerpt: A one-dimensional numerical model was used to determine the effects of sediment deposition in the Corte Madera Creek flood control channel. The effect of accumulated gravel deposits in the concrete-lined channel on hydraulic roughness was evaluated. The effect of a proposed sediment trap at the upstream end of the project on reducing gravel deposits was determined. The performance of the project during a design flood event was simulated. (fr).

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Coastal Watershed Management written by A. Fares and published by WIT Press. This book was released on 2008-05-23 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coastal watersheds differ from others by their unique features, including proximity to the ocean, weather and rainfall patterns, subsurface features, and land covers. Land use changes and competing needs for valuable water and land resources are especially more distinctive to such watersheds. This book covers recent research relevant to coastal watersheds. It addresses the impact of a stream’s chemical, biological, and sediment pollutants on the quality of the receiving waters, such as estuaries, bays, and near-shore waters. The contents of the book can be divided into three sections; a) overview of hydrological modelling, b) water quality assessment, and c) watershed management. This book differs from other hydrology books by dealing with coastal watersheds which are characterized by their unique features: including weather and rainfall patterns, subsurface characteristics, and land use and cover. In addition to academia, the book should be of interest to organizations concerned with watershed management, such as local and federal governments and environmental groups. Overall, the book is expected to satisfy a great need toward understanding and managing critical areas in many parts of the world.

Download or read book Ecology Conservation and Restoration of Tidal Marshes written by Arnas Palaima and published by Univ of California Press. This book was released on 2012-09-08 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: The San Francisco Bay, the biggest estuary on the west coast of North America, was once surrounded by an almost unbroken chain of tidal wetlands, a fecund sieve of ecosystems connecting the land and the Bay. Today, most of these wetlands have disappeared under the demands of coastal development, and those that remain cling precariously to a drastically altered coastline. This volume is a collaborative effort of nearly 40 scholars in which the wealth of scientific knowledge available on tidal wetlands of the San Francisco Estuary is summarized and integrated. This book addresses issues of taxonomy, geomorphology, toxicology, the impact of climate change, ecosystem services, public policy, and conservation, and it is an essential resource for ecologists, environmental scientists, coastal policymakers, and researchers interested in estuaries and conserving and restoring coastal wetlands around the world.
