Summary of Institutional Issues
The paper presents a summary of three other papers presented at the meeting on institutional aspects of stormwater quality planning. The three papers represented views expressed by representatives...
What Will Happen to Local Rural Roads and Bridges
Much of the local rural road and bridge system was not designed for the heavy trucks and farm equipment that are currently using the system. The system will continue to deteriorate unless...
Educating 21st Century Highway Engineers Industry Perspective of Highway Engineer Needs
Civil engineering firms are being confronted daily with the twin issues of recruiting and retaining qualified staff. On highway engineering three factors have converged in the last year...
Plugging the Public Sector Brain Drain
For years, many agencies have been able to hire and retain highly-educated, highly-skilled work forces, even though their wages, incentives and working conditions have not been fully competitive...
The Economic factors of Ground Water Recharge Projects
As a result of the Water Conservation and Water Quality Bond Law of 1986, the State of California is now providing low interest loans to local water agencies to finance ground water recharge...
The Ozone Defense
Ozone is a molecule containing three oxygen atoms. When bubbled through drinking water, the third atom in ozone is attracted away by other molecules, a process called oxidation. This process...
Investigation of Excavatability in the Piedmont
The lateral and vertical variability of rock weathering in the Piedmont presents significant problems in evaluating the probable cost of excavation for deep basements, pipeline, road cuts,...
Alternatives to Fee Simple Acquisition of Property for Estuarine Reserves
The purpose of the Coastal Zone Management Act of 1972 (CZMA), was to encourage and assist state management of coastal areas consistent with federal guidelines. Section 315 of the CZMA...
Integrated Monolayer Flexible Revetment Technology for Coastal Protection
Fundamental considerations for flexible revetment design are given in some detail and the critical need for sound engineering in a total system design approach is strongly emphasized....
A Small Community's Response to Catastrophic Coastal Bluff Erosion
This paper describes the actions taken by a small unincorporated coastal community in Northern California during a series of catastrophic bluff erosional events, which occurred between...
Public Aid to Help Assess Nesting Sea Turtle Populations in Florida
In 1979, the Department of Natural Resources (DNR) initiated a public statewide assessment project by establishing a network of survey volunteers. This network consists of state and federal...
Defending Our Lake Shores
The current high levels of the Great Lakes are nothing new, as the lakes have been fluctuating throughout history. There have been proposals to stop the current rise in the Michigan-Huron...
Infrastructure
Repairs and Inspection
Rehabilitation of a structure in general requires considerations of unique methods of inspection and repair. Since the structures have to remain in service while the repairs are done,...
A Safer Earthquake Design Approach
The Uniform Building Code earthquake code permits taking advantage of a frame's capacity to absorb energy at stresses beyond yield. Dropping that provision would save lives....
Design and Performance of a Siphon Penstock
Siphons can be a cost effective alternative to more traditional means of conveying water to hydroelectric turbines. The City of Ann Arbor, Michigan selected a siphon as the most cost effective...
Joint Consideration of Pipe Breakage and Pipe Flow Probabilities
Two issues of distribution network reliability, namely, probability of pipe failure and probability of the design flow being exceeded have been discussed. Expressions containing measures...
Model for the Optimal Rehabilitation and Replacement of Water Distribution System Components
The objective of the model presented is to determine the minimum cost solution, given the nonlinear nature of the equations required to describe the cost and the hydraulics of a water...
Reducing Maintenance Costs of Irrigation Systems
Reducing the costs of maintaining an irrigation water delivery system is becoming more important as the financial problems of the irrigators become more critical. The maintenance costs...
Weather Modification Regulation for the Twenty-First Century
Those areas in which weather modification law is being altered to fit the twenty-first century are: 1. De-regulation. Regulation of weather modification through mandating professional...
Economic Analysis Tools for Differential Inflation
Economic decisions based on a life-cycle analysis should consider differential increases or decreases in operation and replacement costs and benefits over the project or component life....
