Southern California Edison Company has performed field uplift load tests on concrete driven piles, cast-in-place straight shaft piles and cast-in-place belled piers along transmission...
Taming Lively Buildings
Mechanical damping systems are increasingly being used for controlling dynamic responses of tall buildings. Several types of dampers are described, and compared, beginning with the three...
New Approaches to Rehabbing Old Dams
The U.S. Bureau of Reclamation takes a look at several new ways of building old dams for maximum flooding. A labyrinth spillway was built at Ute Dam near Logan, N.M. to increase reservoir...
Postmodern Engineering
Momentum Place is a postmodern skyscraper in Dallas designed by architects John Burgee and Philip Johnson. The Datum-Moore Partnership, structural engineers, designed the structural system...
Audits & Analyses?New Jersey's Approach
The New Jersey Department of Environmental Protection is responsible for implementing environmental policy and administering a regulatory structure based on reliable research and monitoring....
Sea Level Rise and Coastal Stormwater Drainage
Global sea level rise as a result of the greenhouse effect and the past trend and future projection on the rise are discussed. Potential problems associated with coastal stormwater drainage...
Issues in Specifying Climate Forcing of Variability
Several issues arise in the specification of the role of climatic forcing of variability of water resources. The effects of human intervention must be removed so that the climate signal...
Incorporating Judgment into an Optimization Model of a Wastewater Treatment System
The use of design variable constraints according to textbook and state design standards might cause potentially good designs to be missed and would not capture the fuzzy interaction of...
Investigating and Treating Chromium in Ground Water at a Wood Treater in California
A wood treating facility, operating for more than five years without required permits, contaminated soil and ground water on and offsite. The company moved slowly in response to enforcement...
Plunge Pool Energy Dissipators for Some Dams in Taiwan, ROC
This paper presents a brief description of the characteristics of the plunge pool type energy dissipators, including design considerations, hydraulic model tests, as well as the results...
Modeling of the Undular Jump for White Water Bypass
Two of the authors have reported previously on the hazard that a conventional hydraulic jump with a uniform reverse surface roller presents to white water boaters. The intent is to create...
Coastal Protection Guidelines, Orange County, GA
As a result of coastal storms in the past several years the County of Orange (California) incurred large and unanticipated costs in providing emergency protection for private shorefront...
Wave Height Distribution in the Coupled Harbor
Wave height in a harbor sheltered by a breakwater is studied by numerical simulation and experiment. The coupled harbor, attained by setting up double arm breakwaters, was adopted as the...
Solving Stormwater Drainage Problems Through an Area Drainage Master Study Program
The Flood Control District of Maricopa County, Arizona, is the floodplain and stormwater management agency for the most densely populated county in the State. A major new tool being used...
Outlet Structure Hydraulics
Current detention basin design procedure is to design the outlet structure for two or more return periods. This is sometimes done by combining weirs and/or orifices of various sizes and...
Air-Water Oxygen Transfer at Spillways and Hydraulic Jumps
Dissolved oxygen measurements are reported for seven spillway structures in the vicinity of Minneapolis, Minnesota, corresponding to 27 individual surveys. The surveys are taken during...
On-Site Microcomputer Control of a Combined Sewer Overflow Diversion Structure
This paper describes the design of an inexpensive system for controlling combined sewer overflows using on-site equipment (raingauges, flow gauges, automatic gates, and microcomputers)....
Management Practices for Erosion and Sediment Control in Irrigated Agriculture
Basin irrigating rice can reduce suspended sediment loads in water because the basins serve as sediment retention basins. Furrow erosion causes significant suspended sediment loads in...
Intense Storms and the Runoff Coefficient
During prolonged, intense storms the runoff coefficient increases in value and approaches one irrespective of the vegetation and soil characteristics of the watershed. As the runoff coefficient...
Unique Flood and Drainage Problems in Los Angeles
Storm drainage for the coastal cities has to traverse highly used sandy recreational beaches. Due to new requirements on the construction of storm drains to the ocean, a beach outlet has...
