An Integrated Approach to Structure and Control Design of Space Structures
In this paper the authors have investigated the effect of passive damping on the optimum structural design with active controls. The minimum weight design is obtained by imposing the constraints...
A System Framework for Engineering Risk Analysis
A mathematical system framework is developed to model a series of criteria called performance indices (PI) related to engineering risk in water resources. Such criteria include reliability,...
Impacts of Risk-Based Analysis on Current Design Practices
A summary of hydrologic design standards used by selected federal agencies for the safety evaluation of dams is presented. A computational procedure is outlined to develop hydrologic design...
Hydraulic Transient Analysis on a Micro Computer
The shift toward micros has reduced prices and increased accessibility, permitting engineers to bypass 'bureaucratic' DP departments and run programs as often...
Quality Assurance in a Large Firm
This paper will describe the formalization of the Quality Assurance Program in a large consulting engineering firm. Although Quality Assurance and Quality Control have been a part of normal...
The Charles River Project
The Charles River Project received the 1984 Presidential Award for Design Excellence in Architecture, Engineering, and Urban Planning. Sited between Charlestown and Boston's...
Design and Effectiveness of Urban Retention Basins
Retention basins are recommended by practicing engineers and regulatory agencies for stormwater management in new land developments. They may require considerable space which limits their...
Designing for Flow
Geotextiles used for in-plane drainage can carry surprisingly large amounts of water within their structures. These composite drains, known as sheet drains, prefabricated drainage composites...
Hydraulics and Hydrology in the Small Computer Age
The theme of the 1985 ASCE Hydraulics Division Specialty Conference is ?Hydraulics and Hydrology in the Small Computer Age.? The goal of this conference is to demonstrate innovative hydraulic...
Hydraulic Design of the Strontia Springs Diversion Dam
The hydraulic features which were of primary significance for the project were the diversion tunnel and spillway. The low-level outlet valves and water-supply intake were relatively straight-forward...
In Situ State of Underwater Hydraulic Sand Fills
An approach is described for quantifying the in situ state of hydraulically placed sand fills which are a significant element in the construction of artificial exploration islands in the...
Method for Weakening the Ice Cover in Northern Rivers
The recent acceleration of development activities in the North, mainly related to the development of oil and gas fields, has necessitated the bridging of many arctic streams. In such streams,...
The Sand Mattress Method of Slope Protection
The sand mattress concept offers promise as an economical alternative to sand bag armor for two distinct applications: (1) slope protection for exploratory islands and/or causeway facilities,...
Asphalt Revetments for Slope Protection in the Arctic
Experience in the Netherlands demonstrates that slope protection of coastal embankments subjected to heavy wave action can be accomplished with lining systems made of mixtures of asphalt...
Geotechnical Design of Caisson Islands
There are a number of areas where fundamental geotechnical research is required so that non-conservative, rational and safe design of artificial exploration islands can be achieved. Some...
Dam Pioneers Concrete Variant
The Willow Creek Dam in Oregon is the nation's first dam made entirely of roller compacted concrete. The design and construction of this dam are described and special problems...
MILHY?A Microcomputer Based Hydrologic and Hydraulic Model
MILHY is an interactive, single event, lumped parameter model used to estimate streamflows and water surface profiles. The model was designed for use on basins less than approximately...
Methods for Reliability Analysis of Water Distribution Networks
A detailed review of the literature reveals that there is currently no universally accepted definition or measure of reliability for water distribution networks. The purpose of this paper...
Simulation of Hillslope Hydrologic Response to Snowmelt in Southwestern Idaho
A two-dimensional, variably saturated porous media flow model was applied to vertical hillslope cross section on a first order study basin in southwestern Idaho. The dominant source of...
Soil Movement and Surface Roughness on Wyoming Rangelands
Soil movement and surface roughness parameters were evaluated as a function of response to livestock grazing and semiarid shrub control treatments. Repeated elevation measurements of erosion...
