Use of Geomorphic Data for Assessing Stream Stability at Bridge Structures
The authors recently completed a statewide bridge scour evaluation for the Nevada Department of Transportation, which included evaluation of the geomorphic processes of bank erosion and...

Changes in Ground Water?Surface Water Interaction in the Santa Ana River Caused by Independent Water Resources Management Activities
For the past 18 years, ground water artificially-stored in the Chino Basin, has been managed as a zero-interest bank account. Recent water resources management studies show that losses...

Sims Bayou: The Public Speaks?The Corps Listens
After about ten years of coordinating, planning, engineering, and design, advertising the first construction contract for the Sims Bayou flood control project was only months away. At...

Upper Mississippi River System Environmental Management Program (EMP)
Introduction The Upper Mississippi River Navigation System (UMRNS) is one of the largest Public Works projects existing within the continental United States of America. The system, which...

Environmental Restoration Measures on the Tennessee-Tombigbee Waterway (TENN-TOM)
The Tenn-Tom, opened to navigation traffic in 1985, was designed and constructed to promote environmentally sustainable development. During the past ten years, the original measures have...

Urbanization and Hydrologic Consequences in Simi Valley, California
Regressional analysis of historical hydrological data including rainfall and runoff data reveal that although there has not been a significant temporal change in the amount of rainfall...

Water Quality Enhancement Using Subsurface Detention
While underground detention systems have gained wide acceptance in the quantitative treatment of stormwater runoff, the potential exists for substantial water quality improvement. Although...

Professional Associations Offer Design Resources for Civil Engineers
A civil engineer is trained academically and professionally to meet the challenges and solve the problems of ever expanding world populations. With an increased demand for civil engineers...

Industry Standards for Erosion Control Products�Future Tools for Civil Engineers
In 1990, the International Erosion Control Association (IECA) formed a Cooperative Standards Program (CSP), directed by the IECA Committee on Standards. The purpose of the CSP is to develop...

Marine Engines Emissions for Vessels of the United States Coast Guard
A source testing project was conducted for a select class of ships of the United States Coast Guard (USCG). Pollutants quantified included nitrogen oxides (NOX), sulfur dioxide (S02),...

Suspended-Solids Flux at a Shallow-Water Site in South San Francisco Bay, California
Time series measurements of current velocity and suspended solids-concentration (SSC) made during December 1993 and March 1994 at a shallow-water site in South San Francisco Bay were used...

Channel Restoration of Incising, Mixed Grain Size Streams: Lessons Learned
Aquatic habitat restoration in incising sand and gravel bed streams disturbed by channelization and other human interventions has received little study. These channel systems are characterized...

Stream Instability in Loess Base Channels
The incision of bess base stream channels is a common and destructive response to alterations within a watershed in the midwest. Monitoring and evaluating procedures are being performed...

Restoration of Abandoned Meanders on the Middle Fork Forked Deer River, Tennessee
The Middle Fork Forked Deer River in western Tennessee historically had a sinuous course within a wide floodplain. In the early 1900's, local interests dug large straight...

Simulation of Catchment Response Using RC Network
This paper describes a simple physically-based distributed parameter hydrologic model of catchment response using a network of capacitors and resistors. The effect of topography is modeled...

SAMS: Software for Simulating Streamflow Series
This paper introduces SAMS, a computer software developed for the analysis, modeling, and generation of hydrologic time series such as annual and monthly streamfiows. It is written in...

Optimization Modeling of Complex Surface Water Collection Systems
The New York City (NYC) water supply system is currently being modeled using Linear Programming (LP) optimization techniques. A series of simulations were performed to investigate the...

Impacts of Climate Change in the Missouri River Basin
The Soil and Water Assessment Tool (SWAT) is being used as a base model to simulate the Missouri River basin for prediction of the impacts of climate change on water resources in the region....

Flood Damage Estimates Using GIS Spatial Analysis
The catastrophic flooding in the midwest during the Summer of 1993 and in California in the Spring of 1995 resulted in flood damage estimates in the hundreds of millions to billions of...

Water Balance of the Niger Basin
A map-based method is used to construct a monthly water balance model of the 2.3 million km Niger River basin in West Africa. The watersheds and stream network within the basin are derived...
