High-Profile Tunneling
When a flood left a considerable amount of debris in its wake the replacement of a hydroplant's tailrace high in the Peruvian Andes presented formidable challenges....
Saving Saluda
One of the largest roller-compacted-concrete berms in the United States will stand sentinel in case South Carolina's Saluda Dam undergoes liquifaction in response to strong...
Dealing with Debris
A comprehensive debris-management plan for the city of Houston will facilitate and coordinate the management of debris removal and disposal following a disaster to mitigate any threat...
Potential Effects of San Mining and Debris Basins on Coastal Sediment Supply in Los Angeles County
The potential sediment supply to the coast in Los Angeles has been heavily impacted by human activity. In the context of rational management of beaches as a resource, it is fundamental...

Debris Flow Events at Mountainous Creeks near Santiago, Chile- Hydrologic Analysis
One of the most important aspects in relation to peak flows magnitudes generated in mountainous catchments at the western side of the Andes facing the city of Santiago, Chile (latitude...
Debris Basin Design Procedures
Debris basins are widely used in the southwestern areas of the United States, with the majority of the structures located in the Southern California area. More and more development is...
Glacier-Generated Floods and Debris Flows
Sudden release of glacially impounded water causes catastrophic floods, known as outburst floods, and ocasionally spawn debris flows that pose significant hazards in mountainous areas....
Floodplain Management in Los Angeles County
Los Angeles is located in a geologically young area of the western United States. It is characterized by highly erodible, steep mountains and flat alluvial plains. Located in a semi-arid...
Optical Scatter From a Space Craft Mirror Due to Microscopic Impacts
This article addresses the issue of how micrometeoroid and man made debris in the space environment can adversely change the optical resolution of a mirror. The study used an algorithm...
Spacecraft Wall Design for Orbital Debris Impact
This paper describes a method for obtaining the optimal rise angle of corrugated bumpers for the design of space structures in the event of an on-orbit impact. The procedure determines...
Modeling of Interaction of Small Particulates in Earth Orbit
The hazards posed by small debris is an area of increasing concern for all space systems. Depending on the size and relative encounter velocity of small particulates, there are a variety...
Space Debris
Space exploration has introduced many positive aspects, but there is also a growing problem. From huge rockets to tiny flakes of paint, space debris is cluttering a major area above the...
Blast Densification of a Thick, Loose Debris Flow at Mt. St. Helen's., Washington
Numerous debris flows occurred during the 1980 eruption of Mt. St. Helen's in Washington State. The proposed location of Bridge 12 over Coldwater Creek along State Route 504 is underlain...
Reliability and Validity of Modeling Sedimentation and Debris Flow Hazards Over Initially Dry Areas
Extreme floods may inundate populated areas of a river valley that are normally dry. Two-dimensional flow analysis is a useful method for predicting the spatial and temporal behavior of...
Erosion and Deposition by Debris Flows in Mountainous Channels on North Fork Mountain, Eastern West Virginia
A study of four debris-flow impacted channels in the North Fork Mountain area of eastern West Virginia shows that the geomorphic effect of debris flows on channel morphology is variable...
Size Characteristics of Debris Flow Deposition
The size distribution of debris flow deposition is extremely wide which may contain nearly all particles from clay and colloid to boulder. Particle size and composition have very important...
An Approach to the Calculation Method of Mean Sediment Size
Mean sediment size is an important parameter expressing the characteristics of sediment. Several calculation methods of mean sediment size which are popular at present almost have some...
Assessment Procedures for Lahars, Mudflows, Debris Flows and Debris Torrents
Unique hydraulic and rheologic characteristics of lahars, mudflows, debris flows and debris torrents require specialized assessment procedures. This paper discusses a fourteen element...
Debris Flow Velocity Estimation Methods for Natural Hazard Assessment
Debris flows are a special category of fluid and mass flow phenomena in which natural runoff entrains extremely high concentrations of sediment. The sediment-water mixture has properties...
