This paper describes the use of conjugate gradient method for finite element problems with multiple loading cases. Specifically, we introduce a modified conjugate gradient method for the...
Data Modelling for Steel Frame Structures
The first step to automate any facet of structural engineering is developing a suitable data representation upon which the computer program will operate. However, there is no standard...
What Object-Oriented Programming Can Mean for Structural Engineers
In recent years, object-oriented programming has become an important topic in the computational community. Although generally viewed as a programmers' tool, object-oriented...
Current Developments of the U.S. Great Lakes Shoreline GIS
The Computer Mapping Center of the Detroit District, U.S. Army Corps of Engineers (USACE), in cooperation with the State of Michigan Department of Natural Resources (MDNR), Land and Water...
Sediment Impediment to Boat Launching at Miller Park, City of Avon Lake, Ohio
In 1987 a boat launching facility was constructed at Miller Park, in the City of Avon Lake, Lorain County, Ohio (Figure 1). There have been problems with sediment buildup ever since it...
Field Measurement of Surface Flows in Shallow Estuaries
This paper summarizes our first-year results of an ongoing multi-discipline project, which examines the physical processes of wetlands erosion and loss in coastal Louisiana. Our task is...
Mississippi River Diversions for Marsh Creation
Large scale, uncontrolled sediment diversions from the Mississippi River are proposed by the Corps of Engineers as a means of creating new marsh and reducing the loss of wetlands. These...
The Engineer's Role in Wetland Enhancement, Restoration and Creation
Efforts are being made by the U.S Environmental Protection Agency (EPA), U.S. Fish and Wildlife Service, and the U.S. Army Corps of Engineers (COE), to implement President Bush's...
Freshwater Diversions from the Mississippi River to Wetlands in Southeast Louisiana
Wetlands in the United States are disappearing at a rapid rate due to a variety of manmade and natural causes. In southeast Louisiana, freshwater diversions from the Mississippi River...
Urban Storm Drainage Design Hydraulic Principles
Chapter 6 of the manual on Design and Construction of Urban Storm Water Management Systems discusses the hydraulic principles and equations under which drainage system structures must...
A Conceptual Basis for Developing Model State Water Codes
The crafting of model state water codes must proceed out of the recognition that there are two prevailing philosophies under which resources are allocated. These contrasting systems both...
Drainage Design Criteria: Too Restricted? Too Broad? Too Outdated?
Should drainage design policies be more flexible, leaving the field more open to engineering judgment? Are some policies too loose or broad? Should design criteria more closely reflect...
MORE-A Multi-Objective Ranking Environment for Risk Assessment
This paper explores the development of a computerized decision support system for ranking risks due to environmental concerns. The paper begins with a brief history a comparative risk...
Applying Benefits-to-Costs Analysis for Stormwater Improvement Projects
Benefit-to-cost analyses provide a measure of evaluation for the justification, selection, and prioritization of stormwater improvement projects. Facing increased competition for tax dollars...
49th Street Bridge: A Study in Environmental Planning
The State of Florida, with its substantial environmental legislation, rigorous permitting requirements, and growing public awareness, poses a major challenge for the water resources engineer....
The Danby Pipe Renovation System
This paper describes a pipe renovation system and its structural characteristics which is cost effective and technically suitable in all sizes of pipe from 8 inches (200 mm) to the largest...
Reliability Consideration in Capital Improvement Programs
This paper shows an application of network reliability modeling in water supply capital improvement programs. The proposed approach consists of combining geometrical and structural properties...
A Substructuring Algorithm for Analysis and Optimization of Large Structures on Parallel Machines
