Approximately 100,000 engineers, technicians, and managers in the United States today are called upon regularly to provide expertise in the field of hydraulic dredging. But because dredging engineering is not generally part of the engineering curricula, information is often not available. This important book fills that gap by compiling all the data available today on dredging technology, as well as including theory and applications, dredging methods, equipment guidelines, and recommended practices.

Authoritative, up-to-date guide to dredging theory and practice. From selecting the right equipment, to evaluating environmental impact, to bidding on a project, Handbook of Dredging Engineering, Second Edition, is the last word on modern hydraulic dredging. Edited by John B. Herbich, with contributions by well-know experts in the field, the Handbook examines basic fluid mechanics; dredge pumps; dredging equipment; sediment; pipeline transport of solids; dredging methods; disposal and placement of dredged material; numerical models for predicting the fate of dredged material placed in open water; environmental effects of dredging activities; instrumentation and automation; and project planning. This vital new edition covers major advances made over the last seven years. Three chapters are new to this edition: numerical models for predicting the fate of dredged material...subaqueous capping of contaminated sediment...and removal of contaminated sediments by dredging, with illustrative case studies.

The Northern Gold Fleet is the story of how new gold-dredging technology was applied to the rich placers of the Far North from 1899 to the present, leading to mass production and economies of scale that made previously unprofitable resources profitable. The bucket-ladder dredge was a single, complex apparatus that rivaled ocean freighters in size. At once ugly, spectacular, and awesome, the dredges dug, classified materials, and performed gold-saving and tailing-disposal functions.A richly illustrated and comprehensive history. The Northern Gold Fleet is part environmental, part technological, part corporate, part labor, and part Alaskan in its thrust, offering a picture - both dazzling and absorbing - of how new technology simultaneously helped build the economy and lay waste the resources of Alaska.

This book is the story of people of vision and courage, of a small group of prominent Saint Augustine investors who conceived of the Florida waterway and began the first dredging work; of an obscure group of New England capitalists who provided significant financing and obtained a million acres of undeveloped Florida public land in pursuing what was, at best, a speculative enterprise; of innumerable citizen groups like the Florida east coast chamber associations and the larger Atlantic Deeper Waterways Association that demanded at the turn of the last century what they believed was the peoples right-a public waterway, free of the burden of tolls; and finally, of the U>S> Army Corps of Engineers, who conducted all of the Florida waterway's early surveys and assumed the project's control in 1929 to convert what was once a private toll way into Florida's modern-day, toll-free Atlantic Intracoastal Waterway.

In the 1900s, skipjacks were a familiar fixture in every port on the Chesapeake. Their captains and crews were tough, hardy souls who earned a living in the harsh conditions of the wintertime Bay, dredging for oysters under sail. It was a dangerous but rewarding occupation; boys as young as twelve years old left school to follow their fathers and grandfathers onto the water in an age-old tradition of independence from the farms and factories that were the lot of men in the towns and cities of the region. The author has gone among skipjack captains, gathering stories of exciting events in their lives and reminiscences of how it was in the good times when oysters were healthy and plentiful. They told, too, about the bad times, when storms endangered their lives, or ice threatened their boats, the times when harvests were meager or the price they could get for oysters was too low to cover expenses. Throughout this absorbing book Vojtech has threaded the history of the skipjack, from its beginnings in the late nineteenth century when dredging by sail was the only legal method, to the present when the twin scourges of disease and water quality threaten to put an end to the country's last commercial sailing fleet.

Originally part of Rancho San Miguel, the West of Twin Peaks district was among the last to be developed in San Francisco. Behrend Joost, using the fortune he made to start dredging the Panama Canal, built a railway in 1891 to bring people out to his “cr¨me de la cr¨me” subdivision next to the forest planted by Comstock Lode millionaire Adolph Sutro. After the streetcar tunnel was bored through Twin Peaks in 1918, A. S. Baldwin planned neighborhoods on Sutro’s estate around Mount Davidson. With noted architects and engineers, Baldwin created “residential parks” with well-built Craftsman, art deco, English, and Spanish homes on curvilinear landscaped boulevards. These “suburbs in the city”―among them, Sunnyside, Balboa Terrace, Ingleside Terraces, Westwood Park, Westwood Highlands, Monterey Heights, Mount Davidson Manor, Sherwood Forest, and Miraloma Park―became home to thousands and a unique part of the San Francisco tapestry.

San Pedro was incorporated into the City of Los Angeles in 1909, and grew into one of the world's strategic international ports. The dredging and backfilling of berths and canals have been mirrored in town through the decades as landmarks were demolished, streets altered, and some structures steadfastly maintained.

Eyewitness testimony is notoriously unreliable. Even more so when Kinsey Millhone's only lead is a grown man dredging up a repressed childhood memory-of something that may never have happened...
