Scour Monitoring at Johns Pass and Nassau Sound, Florida
Scour monitoring instruments were installed on two bridges spanning tidal inlets in Florida as part of a research project to develop scour instrumentation. Previous prototype installations...
Equalizing Wet Weather Flows
Sanitary sewer overflows and combined sewer overflows can wreak havoc on communities by flooding basements, contaminating drinking water sources and recreational water bodies, and flowing...
Banking on Bioengineering
Geoenvironmental engineers have traditionally used riprap to protect streambanks and river banks from erosion. In recent years, however, river regulators, permitting agencies, and county...
Microtunneling under Honolulu
Highly congested urban utility corridors present some of the most difficult conditions for construction of new underground pipelines, especially when subsurface conditions are also very...
Scaling the Monument
One of the three phases in the restoration of the Washington Monument was the design and construction of an aluminum scaffolding system with both functional and aesthetic purposes. The...
Dam Breaching: The Rest of the Story

Application of Linear Programming Techniques to Optimize Groundwater Withdrawals for a Pump and Treat System at Aberdeen Proving Ground, Maryland
The U.S. Army disposed chemical agents, laboratory materials, and unexploded ordnance at the O-Field landfill from before World War II until at least the 1950s. Soil, ground water, surface...
Use of Optimization Techniques to Evaluate Ground-Water Management Strategies in the Central and West Coast Basins, Los Angeles County, California
The U.S. Geological Survey and the Water Replenishment District of Southern California are engaged in a cooperative study of the geohydrology, geochemistry, and ground-water management...
Watercourse Master Plans: Two Case Studies
(No paper) The State of Arizona recently established statutes (ARS 48-3609.01) that enable local flood control districts to identify sensitive watercourses for floodplain management. The...
A Statewide Economic Optimization Model for California II: Model and Results

Economic Valuation of Agricultural Water Use for Large-Scale Modeling
(No paper) A state-wide irrigated agricultural production model has been developed for California. The model is an extension of the Central Valley Production (CVP) Model that was most...
Use of Economic Optimization to Evaluate New Facilities
(No paper) The confluence of the Sacramento and San Joaquin rivers and the San Francisco Bay forms the largest estuary on the West Coast. Known as the Bay-Delta, the region supplies drinking...
Use of Economic Optimization to Assess the Value of Water Marketing
(No paper) There is an increasing interest and implementation of water markets as an allocation mechanism for water in the Western U.S. However, the importance of the timing and location...
Roughness Coefficients in Manning's Equation as an Estimating Tool for Bankfull Discharge in Natural Channels
(No paper) This paper compares the results of Annable's work to the roughness coefficients by stream type given in Rosgen (1994) as well as some additional coefficients from the eastern...
Evaluation of a Soil Vapor Extraction System: A Post-Audit Assessment
(No paper) Numerous sites contaminated with volatile organic compounds (VOC) have implemented soil vapor extraction (SVE) systems to remediate the unsaturated zone. The SVE systems have...
