Flow Analysis Used to Diagnose Pipe Capacity and Sewer Overflow Problems in Sydney, Australia

Computer Model for Infiltration System Design
This paper describes a personal computer model which was developed to assist in the design and analysis of infiltration systems. The systems included in the model are infiltration basins,...

Overflow Elimination Benefits from GIS Based Technology
Elimination of wet weather overflows through the rehabilitation of infiltration and inflow defects requires careful analysis of the collection system. The integration of geographic information...

Sewers and Computers
The following is a description of a project performed to reduce excessive infiltration and inflow in a municipal sanitary sewer system and to provide the municipality with a computerized...

Groundwater Remediation at a Superfund Site
Soil and groundwater contamination at the Montana Post & Pole site in Butte, Montana, one of the nation's oldest Superfund sites, has developed into one of the most significant...

Estimation of Field Site Flow Parameters
The paper reports on the use of Kriging to obtain estimates of hydraulic conductivity underneath a rapid infiltration site. The parameters obtained were used in a two-dimensional groundwater...

Comparison of Infiltration Equations Using Flooding Infiltrometer Data
Based on three flooding infiltrometer tests, 27 hydrographs produced by HEC-1 were used to compare peak discharge, time to peak, and storm runoff volume using three infiltration functions....

Existing Sewer Evaluation and Rehabilitation
This manual, Existing Sewer Evaluation and Rehabilitation, Second Edition, provides general guidance and serves as a source of information...

Rehabilitation of Belle Isle Siphon in Boston, Massachusetts

Data Capture with GPS for Sewer Map Updates
The Cobb County Water System in suburban Atlanta, Georgia selected RJN Environmental Associates, Inc. to provide infiltration and inflow (I/I) source detection and mapping services in...

Rainfall and Net Infiltration Probabilities for Future Climate Conditions at Yucca Mountain
Performance assessment of repository integrity is a task rendered difficult because it requires predicting the future. This challenge has occupied many scientists who realize that the...

The Influence of Long Term Climate Change on Net Infiltration at Yucca Mountain, Nevada
Net infiltration and recharge at Yucca Mountain, Nevada, a potential site for a high level nuclear waste repository, are determined both by the rock properties and past and future changes...

Wetting Front Instability in an Initially Wet Unsaturated Fracture
Experimental results exploring gravity-driven wetting front instability in a pre-wetted, rough-walled analog fracture are presented. Initial conditions considered include a uniform moisture...

Laboratory Study of Water Infiltration into a Block of Welded Tuff

Scaling Laws of Gravity Driven Fingering During Organic Liquid Infiltration
Wetting front instability can occur during vertical infiltration of a liquid into porous media, particularly when a fine soil layer is overlying a coarse layer. The result of this instability...

Modified Horton Models for Steady Rainfall
When the rainfall rate is less than the initial infiltration rate, direct application of the well-known Horton equation underestimates the total volume of water infiltrating the soil until...

Infiltration into Thick Unsaturated Alluvial Deposits: A Preliminary Study
An infiltration and dye transport study in an unsaturated alluvial deposit was conducted using a square flooding type infiltrometer over a 50 hour period. Red and blue dyes were added...
