Modeling sediment transport, channel morphology and gravel mining in river bends

Creator:: Nam, Ilgi
Abstract:: A technique is developed and tested to analyze the interaction of flowing water, bed topography, and bedload sediment transport in meandering channels where gravel bars are removed. The method relates the local velocity distribution, bed shear stress and sediment transport conditions to the local bed configuration in river bends before...

Bacterial toxicity and metabolism of three hydrazine fuels

Creator:: Kane, Donald A.
Abstract:: Hydrazine based fuels are used by the Air Force for the Titan II and Minuteman III missiles and the F-16 aircraft and by the National Aeronautics and Space Administration for propulsion systems and the Space Shuttle Program. These uses represent significant production, transportation and storage of these fuels, and, as...

Pile hammer selection by driving stress analysis

Creator:: Barrero-Quiroga, Franklin
Abstract:: This paper presents an application of the wave equation to the problem of selecting a driving hammer for prestressed concrete piles. The potentially damaging effects of these types of hammers on various prestressed concrete piles were analyzed by means of parametric studies carried out on a hypothetical group of problems...

Influence of Concrete and Construction Parameters on Chloride Test Measurements and Critical Chloride Threshold Limits

Creator:: Vaddey, Naga Pavan
Abstract:: The issue of chloride-induced corrosion of reinforcing steel in concrete and its economic impacts are well-known. Chlorides that cause reinforcement corrosion can be from constituent materials used to prepare concrete or can enter the hardened concrete when the structure is exposed to chloride environments. To minimize the risk of reinforcement...

Post-wildfire Investigation of Civil Infrastructure Following the 2018 Camp Fire

Creator:: Schulze, Stefanie S.
Abstract:: Wildland-urban interface (WUI) communities, where forested land boundaries or intermixes with infrastructure, are quickly growing in the US. WUI communities have grown substantially from 1990 to 2010, with an increase of 12.7 million houses and 25 million people. Wildfires encroaching on WUI communities can cause damage to both above ground...

Computerized safety analysis technique for secondary highways

Creator:: Nichols, Kevin Scott
Abstract:: Evaluation of the safety hazards along a highway is usually performed at specific locations and on known hazards. But, it is also important to find any unrecognized hazards and their locations. Many factors contribute to accident potential, and the combined effect of several of them could produce a hazard that...

Large scale model testing of the FMC submerged wave attenuation device

Creator:: Huber, David S.
Abstract:: This report describes the hydrodynamic testing and evaluation of a one-tenth scale model of the FMC Wave Attenuation Device. The purpose of the test was to quantify the wave attenuation characteristics and structural loading induced by a test program of monochromatic incident waves on the submerged structure. The device was...

Analysis of spatial data from terrain models for landslide predictive mapping

Creator:: Santha, Rubini
Abstract:: Landslides are a pervasive hazard that can result in substantial damage to properties and loss of life throughout the world. To understand the nature and scope of the hazard, landslide hazard mapping has been an area of intense research by identifying areas most susceptible to landslides in order to mitigate...

Tidal influence on downstream fining in gravel-bed rivers

Creator:: Coles, Derron Rafiq
Abstract:: This research examines the downstream fining phenomenon as it operates in coastal gravel-bed rivers of Oregon. Downstream fining is a change in bed composition toward smaller sediment sizes in the downstream direction. Changes in stream flow discharge and channel slope affect the rate of bed-load transport, thereby altering the downstream...
