Design Storms for Urban Drainage
The characteristics of design storms for urban drainage are reviewed. There are indications that, under certain conditions, design storms produce runoff simulation results which are equivalent...
Flood Control, Water Conservation, and Urban Change
Los Angeles County has one of the largest, most complex and effective systems of flood control and water conservation facilities in the United States. It includes 14 major dams, 125 debris...
Modeling to Generate Alternatives: A Review
Modeling to generate alternatives (MGA) is a species of multiobjective programming in which some relevant objectives and perhaps some constraints are deliberately left unquantified. The...
Integrating Policy Factors in Stream-Aquifer Models
One of the main issues appearing today in the field of water resources is the management of complex hydrologic systems consisting of surface streams and aquifers. The management problem...
Continuous Modelling of Downstream River Erosion Caused by 40 Years of Urbanization
The US EPA Stormwater Management Model (SWMM3) was installed on an IBM-PC compatible network. The adapted program, known as PCSWMM3, and incorporating a simple algorithm for modelling...
Orleans Parish Drainage Improvements
A case study of the development of an urban drainage master plan for Orleans Parish, Louisiana is presented. The Parish, which occupies an area of approximately 98,000 acres, lies entirely...
Ecological Impacts of Sediment Transport to Tropical Reservoirs
Sediment transport and siltation influence both the longevity and ecology of tropical reservoirs. The sediment load to these systems is typically seasonal and affects ecological processes...
Queensland, Australia - River Diversion Schemes
The east coast of the State of Queensland has high or very high annual rainfall which declines rapidly with distance inland. The area west of the Great Dividing Range, which parallels...
Water Issues in Tropical and Sub-Tropical Australia
The Northern Territory and State of Queensland cover an area of 3. 1 million km**2 and encompass most of the tropical and sub-tropical zones of Australia. Surface and groundwater resources...
Utopia Under Glass
We stand within sight of the day when our reserves of fossils fuel will be inadequate to maintain the type of energy inefficient cities we have grown used to. This exercise in urban planning...
Infrastructure in a Hurry
The City of Austin, Texas has experienced tremendous growth since the early 1970s. Until recently, however, infrastructure development lagged. Now the city is engaged in a $1 billion infrastructure...
Microtunneling: No Pipe Dream
Microtunneling machines developed in Japan and Germany can help install pipes, ducts and cables without disrupting urban activities at street level. A microtunnel is defined as having...
Microcomputer Application of the Florida Standard Urban Transportation Modeling Structure
Over the past five years the Florida Department of Transportation (FDOT), in conjunction with the twenty-one Florida Metropolitan Planning Organizations, has developed the Florida Standard...
Winter Highway Construction
The purpose of this paper is to describe a study of the feasibility of constructing highways in the wintertime in cold regions. The study, sponsored by the Alaska Department of Transportation...
Passing the Public Works Buck
Users and beneficiaries of local and state public works projects are paying a larger share of their cost. State and federal grants and general local revenues are being relied on less....
Interactive Microcomputer Analysis and Design of Light Gage Steel Roof Systems
A hinderance to the widespread acceptance of the cold-formed steel roof Z-purlin in conventionally engineered buildings is due to the lack of a useful and efficient analysis and design...
Urban Energy Systems for the 21st Century: Transition Paths
Alternative energy systems can be expected to be a significant part of advanced, 'intelligent,' infrastructure systems for cities of the 21st Century. The question...
Westway - The Little Word that Killed the Big Highway
The Westside Highway Project, better known as Westway, received a construction permit on February 25, 1985 from the Army Corps of Engineers. Signed by the author, the permit was invalidated...
Three Inexpensive Land Use Allocation Techniques
The current thrust in transportation planning is to make use of manual and microcomputer techniques for providing quick-response travel estimation. In this context, matching land use techniques,...
Facility Location and Land Use: The Urban/Rural Dilemma?A Commentary
A large part of the dilemma associated with the conflicting impacts of facility location and land use is not so much a lack of technical engineering input, but rather the lack of analytical...
