Safety Aspects of Sulfide and Corrosion Studies (
An overview of the hazards involved in performing sulfide and corrosion studies in sewage treatment and collection systems is presented. Important factors which should be recognized in...
Health Effects,Risk Assessment and Guidance for Indoor Radon
Unlike many inorganic elements, radionuclides have no nutritional value. Radionuclides are carcinogenic and uranium is also known to be non-carcinogenic as well. This paper is primarily...
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...
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...
Responsibility/Liability Related to Mudflows/Debris Flows
The combined experiences of the authors during the past few decades indicate that many of the problems and losses related to damage from floods, landslides, mud/debris flows, and water-related...
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...
Facilities Planning in the Caribbean a Case Study
Culebra has significant problems of water scarcity and poor wastewater treatment. In 1984-1985, a formal Environmental Impact Statement (EIS) was prepared for improved wastewater treatment...
Community Relations on Hazardous Waste Projects: A Successful Experience
Promoting good community relations is an integral part of hazardous waste projects. Before field investigations are conducted at a hazardous waste site, neighboring communities should...
