Studies of Hydraulic Jump by the Flow Routing
The high energy of floodwater passing from a reservoir needs to be dissipated to prevent scouring and damage from the dam and other downstream structures. Hydraulic jump is a common way...
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....
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...
Density Currents and Their Application in Hydraulic Engineering: Task Committee Progress Report
The Task Committee on Density Currents and Their Applications in Hydraulic Engineering operates under the Technical Committee on Hydrologic Transport and Dispersion. The Task Committee...
Concrete Lunar Base Investigation
Scientific and industrial operations on the moon require suitably shielded structures. Small structures for limited scientific activities may be constructed from structural elements prefabricated...
Basing Options for Lunar Oxygen for Manned Mars Missions
The use of lunar oxygen to support lunar space transportation reduces Earth launch mass requirements by a factor of 2. In this paper, the authors show that lunar oxygen can also reduce...
Space Station - New Venture/Old Problem
Four key operations-related costs are associated with the Space Station: (1) transportation, (2) data management, (3) sustaining engineering, and (4) integrated logistics. Life cycle cost...
Comparisons Between Space Facilities and Earth-Based Analogs
This presentation will focus on the design of planetary bases and space stations as based on comparative designs for facilities in analogous harsh and isolated environments here on Earth....
A New Approach to Higher Education on Space
Many universities around the country offer various types of space-related programs at undergraduate and graduate levels. These tend to be narrowly focused on space science or aerospace...
Interdisciplinary Course in Engineering Education
Few would disagree that an undergraduate education should equip the engineer with more than technical competence. The subject of this paper includes discussion of a senior-level interdisciplinary...
The Physics of Sediment Transport by Wind and Water
Sponsored by a special projects committee under the guidance of the Sedimentation Technical Committee of ASCE. This collection contains noteworthy,...
Transit Triumph
The 1988 Outstanding Civil Engineering Achievement is Boston's Southwest Corridor, chosen not only for its size, complexity and technology, but for its environmental, public...
Changing Requirements
There are three sections to the presentation. First, a discussion of the changing environment of highway transportation - what are the factors and variables that are changing in the world...
Air Safety?Programs and their Effectiveness
Airplane accidents have always had considerable media attention, particularly, when they involve large numbers of fatalities. Ever since the Airline Deregulation Act of 1978 and the air...
Railroad Safety Programs and Effectiveness
Safety in the railroad industry has been a matter of concern to employees, officers, federal agencies and the general public since railroads came into being. This paper summarizes the...
The Federal Budgetary Process
The paper outlines the federal budget process as it affects highway safety programs. There are a variety of federal programs which come under the umbrella designation highway safety. Those...
Mitigation of Seismic Effects on Water Systems
Historically, earthquakes have caused damage to water systems. In this paper, water system facilities at risk due to seismic activity as well as potential damage mechanisms are identified....
Hydraulic Fill Structures
This volume contains 53 papers covering many aspects of hydraulic fill structures with special emphasis on geotechnical issues. The papers present an excellent review of historical development,...
