Lining the Line
Having succeeded in achieving dry stations and tunnels in mined construction, flexible waterproofing membranes are now being used to waterproof cut-and-cover subway stations and old, leaking...
Containing Spills and Fire
A $95 million project to consolidate five jet fuel supply facilities that serve Los Angeles International Airport is nearing completion. The project shows how codes for wastewater-treatment...
Perfecting Bridge Inspecting
The Massachusetts Highway Department has improved the safety of its bridges and increased its productivity by using networked multimedia to gather and store a variety of data about bridges...
Accessing Atlantic City
Construction of the 2.2 million sq ft Atlantic City Convention Center is well under way. With 486,000 sq ft of exhibition space, the center and accompanying rail terminal could help restore...
Bridge Over the River Karnali
Just as topping Nepal's Mount Everest requires great stamina from mountain climbers, building the Karnali River Bridge in a remote region of western Nepal required six years...
Intelligent Transportation Education
The comprehensive traffic surveillance study for the New York State Thruway Authority (NYSTA) began in late September 1993. The project involved the study of available traffic management...

Hydraulic and Engineering Considerations in Designing Constructed Treatment Wetlands for a Lake Restoration
A 12,600 ha (31,000 acre) hypereutrophic lake in central Florida is being restored by constructing a 2,020 ha (5,000 acre) wetland filter to remove suspended sediments and particulate...
FLODRO 2.0: A User Friendly Personal Computer Package for Flood and Drought Frequency Analyses
The use of personal computers have changed dramatically the way to perform several studies related with hydrological problems. The increased capabilities of the current generation of personal...
Genetic Algorithm Design of Piped Irrigation Systems
The design of piped irrigation systems is a complex matter. In its simplest form it involves the selection of the sizes of pipes and other hydraulic elements so as to ensure that the varying...
Potential Flow Instability Theory and Bed Forms
An extended, generalised version of two-dimensional linearised potential flow theory of fully unsteady fluid flow-sediment bed interaction is presented. In contrast to previous potential...
Value Engineering Changes to the Eastside Pipeline
Value Engineering is a process of applying analytic, creative and evaluative techniques to a project in order to make recommendations that will, when implemented, maximize value and quality...
Wetland Mitigation Evaluation Ten Years After Florida Keys Bridge Replacement
From 1912 to 1935, the Florida Keys were connected to the mainland by Henry Flagler's Overseas Railroad. The 1935 Labor Day Hurricane destroyed most of the railroad from Plantation...
Investigating the Non-Convexity of the Groundwater Quality Management Response Function
Under certain simplifying assumptions, the groundwater quality management model can be considered a function of a limited number of variables that describe both the transport simulation...
Application of the Newton Method in Valve Discharge Coefficient Relationships
This paper presents a methodology that utilizes the Newton Method to compute the dimensionless valve discharge coefficient Cd from a manufacturers valve discharge coefficient Cv. The implicit...
Sediment Transport Modeling for the Glen-Colusa Irrigation District Fish Screen Modifications
The Glen-Colusa Irrigation District (GCID) pumping plant is located on an oxbow of the Sacramento River approximately 100 miles north of Sacramento (Figure 1). The existing fish screen...
Estimation of Bed Material Transport Capacity
A procedure is presented which combines several computational components for the estimation of bed material transport capacity in alluvial channels. Bed load transport is estimated through...
Hydrodynamic Simulations in Sediment-Carried Contaminant Modeling for the Buffalo River, New York
Accurate prediction of hydrodynamics is of great importance to modeling contaminant transport and water quality in a river and to estimating potential exposure contamination levels in...
Experimental Uncertainty and Measurement Errors in Hydraulic Engineering
The Task Committee on Experimental Uncertainty and Measurement Errors was formed to provide information and guidance on current practices used for describing and quantifying measurement...
Coastal Engineering Laboratory and Field Measurements: Some Uncertainties in Measurement
In this paper two examples of uncertainties which can occur in field measurements and measurements in coastal engineering models are examined. These examples are chosen to demonstrate...
