DOWNLOAD EBOOKBy the start of the 20th century, the U.S. Navy had developed a fledgling salvage capability. Today, under the aegis of the Supervisor of Salvage, the Navy routinely handles assignments around the world, guarding U.S. naval and maritime interests and responding to requests for assistance from our allies. Mud, Muscle, and Miracles takes its reader on a journey through the evolution of salvage--from the construction of a cofferdam to reveal battleship Maineat the bottom of Havana harbor in 1911 to the use of side-scan sonar and remotely operated vehicles to recover aircraft debris and complete vessels from the depths. The story is one of masterful seamanship, incomparable engineering, and absolute ingenuity and courage. It is also the history of one of our nation's longest-lasting public-private partnerships--that of the commercial salvage industry and the U.S. Navy. The second edition updates U.S. Navy salvage history through the beginning of the 21st century and chronicles 18 additional, precedent-setting marine salvage and deep-ocean recovery operations.

DOWNLOAD EBOOKFor developing nations, soil erosion is among the most chronic environmental and economic burdens. Vast amounts of topsoil are washed or blown away from arable land only to accumulate in rivers, reservoirs, harbors, and estuaries, thereby creating a double disaster: a vital resource disappears from where it is desperately needed and is deposited where it is equally unwanted. Despite much rhetoric and effort, little has been done to overcome this problem. Vetiver, a little-known tropical grass, offers one practical and inexpensive way to control erosion on a huge scale in both humid and semi-arid regions. Hedges of this deeply rooted species catch and hold back sediments while the stiff foliage acts as a filter that also slows runoff and keeps moisture on site. This book assesses vetiver's promise and limitations and identifies places where this grass can be deployed without undue environmental risk.
