Sedimentation Problems of the Illinois River Valley
Natural and manmade factors have drastically changed the character of the river and resulted in the accelerated deposition of sediments all along the entire river valley. The Illinois...
Fine Contaminated Sediment Erosion/Deposition in the Buffalo River, New York
This paper documents part of a project which sought to characterize sediment transport in the Buffalo River as a contribution toward planning for dredging or in-place containment of the...
Development and Application of the Chesapeake Bay Eutrophication Model
The paper discusses the formulation of a steady-state coupled hydrodynamic/water quality model of Chesapeake Bay. The intent of this model was to provide insight into the processes and...
Sediment Survey of Lake Powell
The 1986 Lake Powell Sediment Survey documented the present storage-elevation relationship and loss of storage from sediment accumulation since the reservoir began filling. From the calculated...
Sediment Variability Mark Twain Lake, Missouri
This paper looks at the historical variability in suspended sediment loads in the Upper Salt River Basin above Mark Twain Lake, Missouri in an attempt to assess the magnitude of suspended...
Martins Fork Reservoir Sedimentation Study
The Martins Fork Reservoir is located on Martins Fork of the Cumberland River in Harlan County, Kentucky. The lake was impounded in December, 1978. Since closure, the lake has experienced...
Silt Run Effectiveness in Withdrawing Sediment
An investigation was conducted during the silt runs on the North Platte River to determine the continued effectiveness of the runs in providing fine sediments to the canal systems downstream....
Utilization of Ground Penetrating Radar to Conduct Sediment Surveys of Frozen Reservoirs
The ground penetrating radar (GPR) system consisted of a control unit, antenna, recorder, a power supply on a sled towed by a snowmobile. A 120 Mhz antenna was utilized and gave excellent...
Sediment Flushing Experiences at Cherry Creek Dam
An overview of the U.S. Army Corps of Engineers, Omaha District's experiences in sediment flushing operations at Cherry Creek Reservoir near Denver, Colorado is presented....
Application of Reservoir Sedimentation Data to Problems of Environmental Management
Application of sediment delivery ratios and sediment routing procedures to sediment measurements provide an alternative approach to the prediction of localized average annual erosion rates....
Reservoir Sediment Sluicing?Laboratory Study
Experiments are being conducted in a 12.2 meter long, 0.38 meter high, 15 centimeter wide flume to examine the behavior of reservoir sediment deposits in response to sluicing. Crushed...
Debris-Flow Research and Engineering Practice
For debris-flow analysis to enter standard engineering practice, future research must extend existing models to deal with major complications that arise in field practice. This paper reviews...
Response of Advanced Composite Space Materials to Thermal Cycling
In addition to microgravity and lack of atmosphere, the space environment provides intense radiation of both penetrating and nonpenetrating types. This paper focuses on the cyclic radiational...
A Study of Damage in Curved Composite Panels
Composite laminates subjected to a low speed impact, such as a dropped tool or a manufacturing load, often develop an internal delamination. This research studied the effects of a circular...
Fatigue Reliability of Space Structures
This paper develops a methodology for calculating the probability distribution for rainflow cycles in a nonstationary Gaussian process. The up and downcrossing rates are estimated for...
Progressive Impact Damage Assessment in Composite Pressure Vessels
At the present time, advanced composites have been widely accepted as engineering materials. Analysis techniques for the response of composite materials and structures to static loads...
Planar Space Structures
This paper describes a construction system which has a number of practical advantages for the development of space structures. It uses relatively thin materials folded into interpenetrated...
Solar Power Satellite - A Re-Visit
The United States should renew activities investigating the production of baseload electrical power for use on Earth from space. Technology change, world events, and the dictates of the...
Solar Water Heater for NASA's Space Station
This paper describes an investigation of the feasibility of using a solar water heater for NASA's Space Station. During the investigation computer codes were developed to...
Indirect Solar Loading of Waste Heat Radiators
Waste heat from space based power systems must ultimately be radiated away into space. The local topology around the radiators must be considered from two standpoints: the scattering of...
