Design Program for Gravity Sanitary Sewers
The Gravity Sewer Design Program Version 2.1 M (GSDP2M) performs the hydraulic design for a conventional gravity sanitary sewer network. GSDP2M is written in standard Fortran 77 for batch...

Application of GIS in Monitoring and Trouble Shooting of Water Distribution Systems
In this study, the suitability of Geographical Information System (GIS) to monitor water distribution systems is investigated. Although GIS applications are widespread, the use of GIS...

Diagnostic Options for Pipeline Rehabilitation
The various diagnostic options utilized for solving pipeline problems/failures continue to increase at a very rapid pace. Field reconnaisance and/or man-entry of pipelines is becoming...

The Danby Pipe Renovation System
This paper describes a pipe renovation system and its structural characteristics which is cost effective and technically suitable in all sizes of pipe from 8 inches (200 mm) to the largest...

Rebuilding Buried Pipelines Without Digging
Advances and refinements in trenchless reconstruction technologies now permit system rebuilding of gravity and low pressure pipelines without excavation. Through the use of cured-in-place...

Network Modeling in a Water System with Ferrous Deposits
This paper presents the experiences and results of a network modeling study. A model for the University of Idaho water supply system was developed and verified to the extent possible with...

A Comprehensive Algorithm for Network Calibration
An explicit calibration algorithm is proposed which provides the direct and rapid adjustment of the pipe roughness coefficients and junction node demands that exactly meet a specified...

Block-based Solvers for Engineering Applications
This paper compares the performance of standard linear system solvers, LINPACK, widely used in engineering applications, and PARALIN (a block-based package for linear systems) on the Alliant...

On the Design of Laminated Composite Flange: A Model with Experimental Verification
A parametric model has been developed for the optimum design of laminated composite flange. The study focuses on the evaluation and performance optimization of composite flanges with the...

Pipeline Crossings
This proceedings of the Pipeline Crossings Conference, held on March 25-27, 1991 in Denver, Colorado, presents information on aspects of various pipeline crossings. It covers such broad...

Cables Not in Trouble
Cable-stayed bridges in the U.S. are not, contrary to reports widely disseminated in the press several years ago, about to fail from corrosion. The design, in which primary cables support...

Pipeline Rehab: Underground Options
While simply digging up old pipes and replacing them is sometimes still best, other alternatives can give long life while easing the strain on the community. Trenchless methods for on-line...

The Pressuremeter: Some Special Applications
The preboring pressuremeter has been used for foundation design for many years. Some recent developments are presented which extend the applications of the pressuremeter. These developments...

In Situ Determination of Smith Soil Model Parameters for Wave Equation Analysis
A methodology for in situ determination of Smith soil model parameters for wave equation analysis is presented. The method uses a small-rod penetration test in conjunction with CAPWAPC...

Expert System for Driven Pile Selection
Selection of driven piles for deep foundations is a complex process. Many subjective factors enter into the decision of which pile to select, making experience an important factor in proper...

Group Efficiency of Piles Driven Into Sands: A Simple Approach
A simplified analysis for computing group efficiency of circular displacement piles in sands is presented. Pile installation is assumed to cause soil displacements in the horizontal direction...

Three-Dimensional Nonlinear Study of Piles and Simplified Models
In a recent study the authors examined the effect of the nonlinear behavior of soil on the axial and lateral response of one or two piles due to monotonic and cyclic pseudodynamic loading...

Monte Carlo Simulations of the Dynamic Response of Pile Groups
A study is presented on the effect of variations of relevant parameters within a pile group on the vertical dynamic response of the group. These parameters include the shear wave velocity...

Modification of P-Y Curves to Account for Group Effects on Laterally Loaded Piles
The response of piles in a rectangular group subjected to lateral loading has been analyzed using a three-dimensional finite element model to evaluate the effect of pile spacing on lateral...
