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...
Factory Chic
Developers of the International Design Center of New York have recently spent $163 million to convert an unused chewing gum factory and a former battery plant into a showcase for New York...
A Digester Gas Cogeneration Plant at EBMUD
Final testing and start-up of a 4. 3 MW digester gas cogeneration plant has been completed and full-time operation begun at the EBMUD Wastewater Treatment Plant in Oakland, California....
Simulation of Natural Resource Systems
Desertification, defined as the loss in productive capacity of the land, has spawned research in decision making involving multi-objective situations. In this study, computer simulation...
Environmental Noise Control for Industrial Facilities
The authors present a brief discussion of the criteria used to evaluate environmental noise control problems. Then, they discuss environmental noise control in the power, petroleum, gas...
Water Resources Applications of OCAP--Ohio's CNRIS
The Ohio Capability Analysis Program (OCAP) is a computer-based natural resources information system (CNRIS) operated since 1973 by the Ohio Department of Natural Resources. The three...
Risk-Cost Analysis and Spillway Design
The NRC's recent report on dam safety proposes risk cost analysis to help select among alternative spillway modifications for existing dams. This paper examines the sensitivity...
The SRI Technique for Flood Frequency Analysis
This paper presents a technique for flood flow frequency analysis called the Storm Response Index (SRI), and a case study using the technique. The SRI method is based on the development...
A Physical-Chemical Interpretation of Mean and Extreme Values in Acid Precipitation
A physical-chemical model is used for the interpretation of mean and extreme concentrations in acid precipitation. Chemical concentration frequency distributions tend to be skewed, as...
Sludge Treatment Design Lands Innovative Funding
The design of sludge treatment facilities for the 10 mgd Ithaca, New York, wastewater treatment plant incorporates both proven technology in the form of gravity thickening and anaerobic...
Prior Planning for Post-Hurricane Reconstruction
Planning for hurricane emergencies has focused upon the period immediately before and after the storm's arrival, emphasizing evacuation and disaster relief. Mitigation of...
Constraints on the Use of Development Management to Reduce Coastal Storm Hazards
This paper has presented some important information about perceived constraints to the enactment and effective implementation of development management measures to reduce coastal storm...
Improved Evaluation of the Federal CZM Program
The Coastal Zone Management Act (CZMA) of 1972 created a federal coastal zone management program by providing funds to states to voluntarily develop and implement plans for the management...
A Comprehensive Planning Approach for the Conservation of Coastal Resources at the Local Level
The recent rapid growth of New Hanover County in coastal North Carolina has created the classic dilemma of an environmentally attractive locality attempting to accommodate desirable growth...
Hazard Mitigation Efforts in the Ocean City, Maryland Area
During a low frequency storm event, there is a considerable hazard along the bay shoreline of Ocean City as a result of high water flowing back over the barrier toward the ocean. The purpose...
Splitting Common-Pool Offshore Oil & Gas Revenues
The Department of Interior (DOI) and several coastal states are currently at odds over an issue with enormous financial stakes as well as far-reaching implications in federal/state relations....
Density Transfer: The Santa Monicas Contribution
This paper addresses some aspects of designing and implementing density transfer programs, as illustrated by the Transfer of Development Credit (TDC) program which the California Coastal...
Stormwater Routing for Small Sites
Traditional hydrologic analyses and detention design procedures are too time consuming and costly to be warranted for small projects. This paper discusses a direct solution for sizing...
Estimating Peak Flow Reduction in Small Reservoirs
A microcomputer program is used to provide a simple and rapid estimate of the peak outflow from such reservoirs. Peak flow values, determined by flood frequency analysis or regional flood...
Computational Model for Computing Dune Erosion
This paper summarizes the development of a computer model for determining potential beach and dune erosion along the Florida Panhandle. The results have been used as a guide in delineating...
