Hydrologic Comparison of Four Types of Permeable Pavement and Standard Asphalt in Eastern North Carolina
A permeable pavement parking lot in eastern North Carolina consisting of four types of permeable pavement and standard asphalt was monitored from June 2006 to July 2007 for hydrologic...

Some Case Histories of Pile Foundations in Permafrost
Foundations for permafrost conditions should conform to one of three basic design principles: keep it frozen, let it thaw, or thaw the ground before construction. To keep the permafrost...

Headcut Analysis for Off-Channel Gravel Pits in Arid Environments
The study focuses on a large gravel pit located adjacent to the Santa Cruz River between the confluences with the Rillito and Canada del Oro rivers in Tucson, Arizona. These gravel pits...

Stochastic Analysis of the Truckee River Flow System
The Truckee River system is a complex system that involves a number of hydraulic structures such as natural and artificial lakes and reservoirs and diversions. Streamflow data have been...

Reconstructed With Precision
Rehabilitating a heavily traveled crossing while traffic continues to flow is a complicated endeavor. Add the attention to detail required to preserve the character of a historic 1920's...

Pressure Relief
When the two basins making up a 90 acre reservoir in New York needed to be emptied and cleaned, engineers decided to use the 2,750 ft (840 m) long concrete wall dividing them as a dam....

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....

A Paradigm Shift in Irrigation Management
In coming decades, irrigated agriculture will be called upon to produce up to two thirds of the increased food supply needed by an expanding world population. But the increasing dependence...

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,...

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...

Control of Microorganisms in Drinking Water
Prepared by the Water Supply Engineering Technical Committee of the Infrastructure Council of the Environmental and Water Resources Institute of ASCE. ...

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...

Comparison of Hydrodynamic Parameters for a Floating Breakwater
The U. S. Army Engineer Research and Development Center is in the process of developing a Rapidly Installed Breakwater System (RIBS) for use in Joint Logistics Over the Shore Operations...

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...

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...

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...
