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...

Montioring and Modeling of Tandem Breakwater System at Hammond, IN
A tandem breakwater system was constructed in 1989-90 to provide protection for a large marina at Hammond, IN, at the south end of Lake Michigan. A five year monitoring program (1993-98),...

Advances in Buoy Technology for Wind/Wave Data Collection and Analysis
Considerable advances have been made recently to reduce the cost of gathering meteorological and oceanographic data from coastal waters, especially for meteorological and oceanographic...

St. George Habor—Berm Breakwater Construction Considerations
During the period 1984-1987 three berm breakwaters with a total length of approximately 800 meters were constructed at St. George Harbor on St. George Island in the Pribil of Chain of...

Re-Publication of Important Documents of the ASCE Urban Water Resources Research Council

Weighing the Options
A unique sludge pipeline replacement project in Colorado gave the engineers and the owner an opportunity to compare the merits of three different project delivery methods....

Clean Water at the Crossroads
Thirty years after the passage of the Clean Water Act, the quality of effluent from the nation's wastewater treatment plants has improved considerably. However, much of the...

Rapid Delivery
Facing nearly dry wells and a moratorium on development that was about to expire, a small town in the pacific Northwest, using the design/build delivery method, was able to quickly design...

Natural Progression
Engineers made storm-water detention, wetlands mitigation, and environmental safeguarding part and parcel of an industrial expansion project. Designers have created an inviting front yard...

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...

Uses and Limitations of Conventional Hydraulic Models in the Planning and Design of Storage Tunnels
The hydraulic design of storage tunnels requires special considerations relative to the design of conventional sewers. These issues include characterization and control of inflows, energy...

Freight Pipelines: Past, Present and Future
Freight pipelines are a set of time-honored methods to transport solids by underground pipelines, and the technology is improving. However, for intercity and interstate freight transport...

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
