The Past, Present & Future of Earthmoving Scrapers
This paper is a summary of the history and development and use of earthmoving scrapers. It will also take a look at the future of this type of machine. We'll build the discussion...

Lessons Learned from Design, Construction, and Performance of Hydraulic Structures
The intent of this publication is to provide lessons learned, both positive and negative, from activities associated with design, construction, and performance of hydraulic structures....

Keeping Sand at a Standstill
Construction of roads, railroads, pipelines and other facilities removes the native vegetation from sand dunes. As a result, sand movement starts and entire dunes may become active. This...

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...

Structural Monitoring Concepts for Arctic Pipelines
Terrain instabilities producing differential soil movements are the predominant features affecting the structural integrity and design of buried pipeline systems in the arctic. Current...

Pipeline Frost Heave Predictions Using a 2-D Thermal Model
Chilled structures founded on initially unfrozen soils cause a zone or 'bulb' of frost to develop with time. This time period may be of seasonal duration, as...

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...

Research on Transportation Facilities in Cold Regions
Transportation facilities research in cold regions, reported in this session proceedings, begins with a field study showing that ground surface characteristics have a significant effect...

Cleaning the Nut Island Outfalls
As an early component of a comprehensive program to reduce pollution in Boston Harbor, two 80-year-old cast-iron outfalls, each 60 inches in diameter and a mile long were cleaned in a...

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...

The United States Used to be a Great Country...
Up until 20 years ago, the American highway departments did a good job of maintaining bridges and they kept streets well paved. The public works departments maintained the water and sewer...

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,...
