Identifying Potential Trophic Relationships and Bioaccumulation Pathways between Fish and Invertebrates
A large ocean monitoring database was used to quantify relationships between demersal fish, epibenthic macroinvertebrates (EMI) and benthic infauna that provide potential pathways for...
Determination of Bridge Scour Velocity in an Estuary
Determination of the appropriate design for protection against bridge pier scour depends significantly upon the design velocities at the project site. In estuaries with large influences...
Sanitary Sewer System Modeling Model Comparison Racine, Wisconsin
As the use of computers continues to increase within the engineering profession, hydraulic computer models are used to simulate major interceptors and sometimes the entire sewer system....

Flood Control Studies for Arizona Communities
Severe flooding in the winter of 1992/1993 produced severe flooding across the State of Arizona. Damages were widespread and significant. Total public and private damages are estimated...
Evaluation of System Downstream Control
System downstream control (SDC) has been developed to optimally and automaticaly control canal systems. The objective of system downstream control is to maintain a reference water depth...
Earth Spillway Design Using SITES Software
The USDA Natural Resources Conservation Service has, recently released new software for the design and analysis of water resource structure sites. This software, SITES, is based on the...
Engineering Aspects of Wetland Mitigation
Wetland mitigation demands a multi-disciplinary engineering approach, and a systematic collection, evaluation and analysis of data. The design of a constructed wetland addresses these...
Emergency Repair of an Ocean Outfall
The County Sanitation Districts of Orange County (Districts) provide wastewater collection, treatment and disposal services for more than 2 million people in metropolitan Orange County....
The South Bay Ocean Outfall
For more than 60 years, raw sewage has flowed down the hills of Tijuana, Mexico into the Tijuana River, crossing the U.S.-Mexican border. The sewage contaminates the low-lying river valley...
Biological Serendipity from an Ocean Outfall Maintenance Inspection
A large deep-water ocean outfall discharging ?880 x 106 liters day (230 million gallons day of treated wastewater effluent was inspected with a one-man...
External Inspection of an Ocean Outfall
In October and December, 1994, an external inspection was performed on the County Sanitation Districts of Orange County's (Districts) ocean outfall. This presentation describes...
