Scour Study for Bridge Design on Temecula Creek
Channel-bed scour was studiedfor the proposed new Pala Road Bridge on Temecula Creek in Riverside County, California. In order to determine the general scour, sediment transport and potential...
Design of Riparian Habitat Replacement in Active Floodplains
Conventional flood control engineering techniques and approaches that have been traditionally been applied are now challenged by the public and no longer readily available as floodplain...
The Balanced Indigenous Population (BIP) and Statistical Process Control (SPC) in Marine Pollution Ecology
This account discusses the regulatory requirement of maintaining a Balanced Indigenous Population (BIP) as it relates to an ocean outfall. A brief history of the development of the BIP...
Overview of the US Army Corps of Engineers Flood Control Channels Research Program
The objective of the Flood Control Channels Research Program, currently being conducted at the US Army Engineer Waterways Experiment Station, is to develop design guidance and systematic...
Use of Channel Forming Discharge Concepts for Flood Control Channel Design
Evidence suggests that for perennial and ephemeral rivers that are in regime, bankfull flow is strongly correlated with channel morphology. Evidence suggests that this discharge is also...
Pollutant Transport Across Porous Stream Beds
The presence of porous streambeds generates a significant interaction between the main stream flow above it and the flow through the porous sub-stratum. This coupling affects both flows,...
Biopolymers for Geotechnical Applications
A number of bacteria, e.g.,
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...
A Screening Level Model for Estimation of Vadose Zone Leaching and Saturated Zone Mixing: VLEACHSM
A screening level computer model has been developed for the evaluation of pollutant migration through the vadose zone and subsequent mixing within the saturated zone. The model, called...
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....
Non-Federal Flood Control Works Inspection Program
This paper presents a general description of the Non-Federal FCW Inspection Program and results obtained from the evaluations already completed. A discussion of the GIS package for data...
Testing and Effectiveness of a New Urban BMP Storm
Stormwater management for water quality control, pollution prevention and pretreatment can be a difficult problem for the development design professional, a costly and time consuming problem...
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...
Floodplain Analysis of the Lower Santa Margarita River in Camp Pendleton Marine Air Base, California
Floods of 1993 caused extensive flooding of the Santa Margarita River, and significant damage to Camp Pendleton. A floodplain analysis was performed including an assessment of recent flood...
Alachlor Transport in Laboratory Soil Columns
Spraying of agricultural chemicals result in their travel downward through the unsaturated zone and adsorption to the surrounding soil. Infiltration from rainfall and irrigation solubilize...
Predicting Transport of Organics through Soil Columns using Distributed Mass-Transfer Rates
A numerical model to describe contaminant transport through soil columns, including distributed mass-transfer, is developed. Both a gamma distribution and a lognormal distribution are...
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...
