Landslide Dammed Lakes at Mount St. Helens, Washington
The collapse of the north face of Mount St. Helens on May 18, 1980, and the debris avalanche that resulted blocked outflow from Spirit Lake and Coldwater and South Fork Castle Creeks....
Engineering Implications of Impoundment of the Indus River by an Earthquake-Induced Landslide
Historical records and physical evidence indicate that in the Himalayas of northern Pakistan a huge landslide dam was caused by an earthquake in 1840. The dam blocked the Indus River,...
Landslide Dams in Japan
Damming of rivers by landslides is common in Japan because widespread unstable slopes and narrow valleys exist in conjunction with frequent hydrologic, volcanic, and seismic landslide...
Landslide Dams in South-Central China
The Yangtze and Yellow Rivers and their tributaries drain mountainous areas of south-central China that are highly susceptible to landslide activity. This paper describes six major cases...
Reshaping Providence
By moving railroad tracks, river banks and several roadways, Providence, Rhode Island is reclaiming some 45 acres in its downtown and capital districts. This public works package is the...
Terminal Development as Affected by New Generation Ships
Howland Hook Marine Terminal, New York, serves to illustrate how an existing terminal, built to the older standards, can be adapted to accommodate these larger ships that not only stretch...
Planning for Deep-Draft Navigation Channels
This paper summarizes the trends in seaboard trade, the major commodities for the world, and the share captured by U. S. ports. The discussion includes the new developments of port planning...
Ship Wave Prediction for Port and Channel Design
Several laboratory and field investigations of ship-generated waves have been conducted during the past twenty-five years. Typically, for a given ship, reported data consists of the height...
Navigation Channel Design for Safe and Efficient Ship Transit
The U. S. Army Engineer Waterways Experiment Station (WES) recently conducted a hydraulic model investigation of the western portion of Cleveland Harbor, Ohio. This study provided data...
Channel Design Criteria and the Houston Ship Channel
Channel design literature is reviewed and compared with operational limits currently on the Houston Ship Channel (HSC). It was found that in all aspects of channel design considered (depth,...
Additional Benefits from Channel Improvements
This paper describes techniques used to quantify three types of benefits resulting from enlarging the Houston Ship Channel. These benefit types are vessel casualty reduction, delay reduction...
Analytical and Empirical Methods for Predicting Channel Shoaling
Many techniques have been used in the past to predict the effects of channel enlargement on channel shoaling. These range from rule-of-thumb predictions to elaborate physical model investigations....
National Port Issues
The adequacy of U. S. ports to meet the Nation's present and future needs was evaluated by a Committee of the Marine Board, National Research Council. The changing character...
Landslide Dams
Processes, Risk, and Mitigation
Landslide dams have proved to be both interesting natural phenomena and significant hazards in many areas of the world. A few of these blockages attain heights and volumes that rival or...
Plugging into a Dam
Instruments are embedded into hundreds to dams around the world. But for instrumentation to be effective, the instruments must be read, and the data must be plotted and compared to predicted...
Fast, Economical, Cone Testing of River Sediments
The objective of the study reported was to obtain quantitative geotechnical information over many square miles of Hudson River bottom. A hand held cone penetrometer was selected for use....
Viscoplastic Fluid Model for Debris Flow Routing
This paper describes how a generalized viscoplastic fluid model, which was developed based on non-Newtonian fluid mechanics, can be successfully applied to routing a debris flow down a...
Cherokee Nation Power Development at a Corps Lock and Dam
In an arrangement among the Cherokee Nation of Oklahoma, the U. S. Army Corps of Engineers and the Southwestern Power Administration, the Cherokee tribe will finance, design and construct...
Remote Sensing to Assess Effects of Hydroelectric Development
Planning for hydroelectric development of rivers in the province of Ontario, Canada requires extensive environmental evaluation and assessment. To test the feasibility of using digital...
Flood Risk Below Steep Mountain Slopes
Alluvial fans spread at approximately the critical hydraulic slope below apexes at canyon mouths. Periodic torrents that rage out of the canyons are devastating at the apex and have diminishing...
