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...
Experiences with Military Installation Drainage Systems
This paper presents a brief survey of experience with drainage systems found on Army bases. In addition, selected current drainage-related research topics which support Army installations...
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....
Flood Hazard Scenarios in a Pleistocene-Holocene Basin
Technical scenarios are used to characterize the flood hazard in the Bayou Fountain Basin, an area of complex geomorphology and urbanization. Floods from three sources, 1) local precipitation,...
Model Mania in Urban Hydrology: Present Dilemmas
A recent ASCE Task Committee on microcomputer software in urban hydrology has just completed its inventory of 40 software packages available at modest cost to the urban drainage engineer....
Hydrologic Modeling for Decision-Makers
All Properties within a community benefit from having an adequate system of storm drainage facilities and controls. Such benefits include: reduction of hazards to property and life resulting...
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...
Stormwater Quality Issues for Jefferson Parish
Jefferson Parish has a unique set obstacles to overcome in the operation of the drainage system. Situated in a coastal area and surrounded by water, the area has been developed through...
Evaluation of Stormwater and CSO Impact on Portland's Columbia Slough
A team of consultants studied the impacts of stormwater and combined sewer overflows on an urban drainageway to determine if increased beneficial stream uses were attainable. Planning-level...
A Hybrid Expert System for Design with Geosynthetics
A prototype hybrid expert system is presented that selects geosynthetic materials and performs detailed designs for different geotechnical applications. An expert system is used to give...
Geotextile Edge Drain Design and Specification by Expert System
Expert systems can be developed and operated on personal computers to aid in the design of the geotextile filter component of pavement edge drains. The expanding use of geotextiles in...
Development of Long Beach Downtown Marina
This paper describes the planning and construction of the new Alamitos Bay Marina just offshore of Long Beach's downtown shoreline. From an engineering standpoint the construction...
The Petroleum Geology of the Oceanside Trough, Capistrano Basin, Offshore Southern California
The Caoistrano Basin represents one of the last essentially unexplored Neogene depocenters along the southern California coast. Within the greater Capistrano Basin, the Oceanside Trough...
Effect of the Earth Rotation on Tide Induced Sediment Transport
Semi-enclosed seas are generally composed of narrow straits and wide basins, forming a strait-basin system. In the strait-basin system where tidal current prevails, the strong tidal current...
Trapping and Escape of Fine-Grained Sediments: Neuse River Estuary, N.C.
The Neuse River estuary and its receiving basin, Pamlico Sound, are part of a system that comprises large, shallow bodies of water which have little or no free connection with the open...
An Engineering Evaluation of Fine Sedimentation at the Mayport Naval Basin, Mayport, Florida
The Mayport Naval Basin is located near the mouth of the St Johns River in northeastern Florida, U.S.A. A total of 16.8 million cubic yards of fine sediment were dredged from the harbor...
The Stratigraphic Record of Oxygen Isotope Stage 5 on the Maryland Inner Shelf
Present knowledge of Holocene transgressive coastal/shelf systems, while extensive, cannot directly address the effects and consequences of an extended period of relatively high sea levels...
Beach Stabilization Using Drains?An Experimental Model Study
The use of the drain concept may be an attractive new tool for beach stabilization because it provides an alternative to hard structures and may enhance beach nourishment practices. Two-dimensional...
Composite Liner, Leak Detection System, and Floating Cover for Nuclear Reactor Emergency Retention Basins
Existing reactor effluent basins are being retrofitted with composite liners, leak detection system and floating covers. Such basins have a 15-year life and remain empty until an accident...
Modeling Analysis of CSO Impacts in a Tidal Basin
Short duration intensive inflows of combined sewer overflows (CSO) to marine tidal basins create stratified water quality for limited periods of time. Accurate assessment of water quality...
