San Diego Delivers
To maintain its ability to provide water to some of its rapidly growing regions, the city of San Diego is simultaneously laying two large diameter pipelines, one carrying potable water...
Shell of Steel
To create a saddle-shaped bandstand in a newly developed park in St. Paul, Minnesota, engineers designed a glass-covered, stainless steel lattice grid that makes use of a unique system...
What Is Hydraulic Engineering?
This paper, written to mark ASCE's 150th anniversary, traces the role of hydraulic engineering from early or mid-twentieth-century to the beginning of the twenty-first century....
Development of Transportation Engineering Research, Education, and Practice in a Changing Civil Engineering World
Transportation has been one of the essential areas within civil engineering since its early days. In commemoration of the 150th anniversary of ASCE, this paper presents a review of developments...
Unleashing the Flow
A 70-year-old, two-lane roadway that stretches from Miami to Tamp Bay is impeding the flow of water through the Everglades. By studying eight possible solutions in detail, engineers determined...
Impact of Ground Water Management on the Hydropattern of Wetlands
In this paper, we examine the effect of altering the pumping rates of a large municipal well field, on the hydropattern of the near by PENSUCO wetland. A flow model developed earlier using...
Leakage Control?Finding a New Resource from the Existing One
It is estimated that by the year 2005, one person in two will have an insufficient supply of one of the world's most precious elements: water. Worse still, it is predicted that this shortage...
Practical Groundwater and Conjunctive Water Optimization
The Simulation/Optimization MOdeling System (SOMOS) makes it easy to do groundwater optimization modeling for a variety of scales and situations. The SOMOA module uses analytical equations,...
Replacing a Dying Water Infrastructure
The water infrastructure in the United States will soon need massive repairs. Pipes are leaking, and most pipes are near the end of their life cycles. Tens of thousands of sewer overflows...
Environmental Fluid Mechanics
Theories and Applications
Sponsored by the Fluids Committee of the Engineering Mechanics Division of ASCE. This report provides environmental engineers with a comprehensive...
Deep Freeze
In engineering, overcoming a failure can sometimes be more instructive than completing a project with unqualified success. Such was the case with the collapse and repair of a force main...
Application of a SonTek Argonaut Side-Looking (SL) Doppler Flow Meter for Measuring Discharge on the Southern Leg of the Parana' River at the Entrance to the Itaipu Binacional Reservoir, Parana', Brasil
Index-velocity and water level data collected with a SonTek Argonaut Side-Looking (SL) Doppler Flow Meter and channel cross-sectional area data were used to compute total discharge on...
Establishing Baselines For Pipeline Condition Master Planning
As our most of our cities approach complete built-out and much of our wastewater pipelines near the end of their design life, attention needs to be focused on retiring deteriorated first...
Quality Control Test for Prestressing Wires in Concrete Pressure Pipe
Prestressed concrete cylinder pipe (PCCP) was introduced in 1942 as a high pressure capacity conduit for water transmission. The principal element of the design and construction that imparts...
Multifaceted Trenchless Rehabilitation at the Middletown, Ohio WWTP
This paper describes the multiple trenchless technologies that were evaluated and the ones that were applied to the rehabilitation of a 78la diameter corrugated metal influent line and...
Non-Destructive Excavating Around Pipelines and Challenging Conditions
Hydrovac technology provides engineers and contractors with a unique solution for non-destructive excavating around sensitive buried lines. As a non-mechanical excavating method, it is...
Use of New Liner In Water Distribution System
For years there has been interest in rehabilitation of water distribution systems to provide quality drinking water and to reduce breaks in the water system service. Much work has been...
Installation of Fiber Optic Cables in Sewers Using a CIPP Process
Although using sewers as an avenue for the installation of Fiber Optic Cabling is a relatively new concept, there have been several major technological advances in the installation process...
The Determination of Velocity Spectra and Dissipation by Direct and Indirect Means using Second-Order Accurate PIV
In this paper we present a 2 nd order accurate technique in space (following Wereley & Meinhart's (2001) extension of Cowen & Monismith's (1997) dynamic sub-window PIV...
Erosion from an Industrial Forest Road in the Ouachita Mountains of Southeastern Oklahoma
Erosion from 4 segments of a 2-year old forest road in a 740 ha basin was measured for each of 105 storms that occurred in a 3.5 year period. Two road segments were part of a mid-slope...
