Development Of A Decadal Scale Estuarine Geomorphic Model For Suisun Bay California

This collection contains 66 papers on estuarine and coastal models presented at the Eighth International Conference on Estuarine and Coastal Modeling, held in Monterey, California, November 3-5, 2003.

One of California's most remarkable wetlands, Suisun Marsh is the largest tidal marsh on the West Coast and a major feature of the San Francisco Estuary. This productive and unique habitat supports endemic species, is a nursery for native fishes, and is a vital link for migratory waterfowl. The 6,000-year-old marsh has been affected by human activity, and humans will continue to have significant impacts on the marsh as the sea level rises and cultural values shift in the century ahead. This study includes in-depth information about the ecological and human history of Suisun Marsh, its abiotic and biotic characteristics, agents of ecological change, and alternative futures facing this ecosystem.

An ecosystem in freefall, a shrinking water supply for cities and agriculture, an antiquated network of failure-prone levees—this is the Sacramento-San Joaquin Delta, the major hub of California's water system. Written by a team of independent water experts, this analysis of the latest data evaluates proposed solutions to the Delta's myriad problems. Through in-depth economic and ecological analysis, the authors find that the current policy of channeling water exports through the Delta is not sustainable for any interest. Employing a peripheral canal-conveying water around the Delta instead of through it—as part of a larger habitat and water management plan appears to be the best strategy to maintain both a high-quality water supply and at the same time improve conditions for native fish and wildlife. This important assessment includes integrated analysis of long term ecosystem and water management options and demonstrates how issues such as climate change and sustainability will shape the future.

This book presents a number of modeling studies of various water resources systems in the humid tropics and the typical short, steep mountain-to-coast systems in the archipelagic setting of the Philippines. Covering natural and rural systems, urban watersheds and built systems, such as reservoirs and flood control systems, it discusses modeling studies based on pure simulation and combined optimization-simulation. The book offers insights into real-world water resources modeling, and as such is a valuable resource for academics and practitioners in the Philippines, as well as those in other Asian regions with similar water resources systems, and similar issues, problems and concerns.

From considerations of energy balance and of mechanical equilibrium, a mathematical expression is derived relating the rates of sediment transport as bedload and as suspended load to the expenditure of power by a statistically steady flow of water.
