Iona Outfall Plume Characterization Study
Field studies were conducted in August 1988 to verify the performance of the new deep sea outfall for the Greater Vancouver Regional District (GVRD) Iona Island Sewerage Treatment Plant...

Synthetic Calibration of a Rainfall-Runoff Model
A method for synthetically calibrating storm-mode parameters for the U.S. Geological Survey's Precipitation-Runoff Modeling System is described. Synthetic calibration is accomplished...

Bootstrapping Nonlinear Storm Event Models
A bootstrap method for estimating the parameters of nonlinear storm event models is presented. The method pools (combines) the parameter estimates obtained from fitting computed and observed...

A Regionalized Rainfall-Runoff Stochastic Model
The single area unit hydrograph model is used to develop a distribution model which accommodates the uncertainty in rainfall over the catchment. By categorizing the available rainfall...

The Hydraulic and Hydrological Interactions Between Urban Sewer Systems and Receiving Waters at High Discharges
In the transition region from sewer to river, the penetration of river flood water into the sewer network or the hydraulic overload of small rivers due to sewer system discharges, may...

Effect of Barrier Beach Breaching on Harbor Dynamics and Storm Surges
This paper presents a summary of the flood insurance study, commissioned by the Federal Emergency Management Agency, to determine the 100-year flood elevation for Chatham, a seacoast town...

Urban Stormwater Quality Enhancement
Source Control, Retrofitting, and Combined Sewer Technology
This proceedings contains the papers presented at the Engineering Foundation Conference on Urban Stormwater Quality Enhancement - Source Control, Retrofitting and Combined Sewer Technology,...

Upgrading Antique Sewers
In a $35 million, four-year program, the Massachusetts Water Resources Authority (MWRA) completely restructed the pumping system serving the sewers under East Boston, Chelsea, Revere and...

Strategic Sanitation Planning
Conventional sewerage has generally been the only method considered for human waste and wastewater disposal in urban areas, both in developed and developing countries. In developing countries,...

The Pros and Cons of Public Education
Today, engineers work for a public that has lost faith in the government's ability to spend money efficiently and to contain pollutants effectively. Many engineers now see...

Buying Tomorrow's Water
Cities are finding that selling future access rights to sewer and water treatment plants can get them needed expansion capital. Although the access rights system is similar to development...

Sediment Transport Processes at Sandbridge, VA
Sandbridge Beach is a primarily residential community located along a 7 km reach of narrow barrier beach. Rates of erosion in this area historically have been high, reaching as much as...

The Coastal Breach at Nauset Beach, Chatham, Massachusetts?A Case Study
Nauset Beach, a barrier spit separating Pleasant Bay from the Atlantic Ocean at the town of Chatham, Massachusetts on Cape Cod, breached in a severe storm on January 2, 1987. The breach...

Sensitivity of Non-Point Source Models to Net Rainfall
A sensitivity analysis of the ANSWERS model was conducted to explore the possible impact on model outputs of discretizing rainfall input data into short time increments of various durations....

Economic Impacts of Storm Sewer Design Criteria
This paper discusses the selection of storm sewer design criteria and the resulting economic impacts. Using the Rational Method for calculating design flows, an investigation was made...

Urban Stormwater Runoff Management
Local land use regulations managing stormwater runoff in new urban developments are the most practical and effective method to control pollutants in urban stormwater runoff or prevent...

Flood Warning Using Wide-Area Computer Networks
Wide-area computer networks are being used with increasing frequency to improve regional response to flood events, coordinate efforts between agencies and communities, and to improve flood...

Relief of an Urban Storm Drainage System
The Peaks Branch storm sewer system was designed in the 1930s to drain 5.7 square miles of East Dallas. Subsequently, development blocked the emergency overflow paths and many areas are...

Analysis of Storm Sewers During Surcharge
A mathematical model based on a lumped system approach is presented to simulate unsteady flow in storm sewers during surcharge. The model equations and method of solution are presented....

Comparison of Tenn-V and TR-55 on TVA Watersheds
The storm hydrograph simulation models TENN-V and TR-55 were compared as to their respective abilities to reproduce 468 storms observed on 54 watersheds. TR-55 did not represent the Tennessee...
