Setting Competitive Water Reuse Rates
Palm Beach County Water Utilities Department (WUD) is preparing to provide reclaimed water service to several large irrigators near the County's Southern Region Wastewater Treatment Plant...

Wastewater Reclamation at Davenport, Washington
The City of Davenport, Washington went through an extended process to update their undersized wastewater treatment and irrigation reclamation systems for municipal wastewater. The process...

Reducing Discharges from San Francisco to the Bay
The City and County of San Francisco (City) is fairly unique in the west because it has a combined sanitary and storm water system. When the current Wastewater Master Plan (WWMP) was completed...

Administering a Regulated Riparian System of Water Rights
Western states, facing steadily increasing demands on limited water resources, have developed administrative regimes for regulating water use based on the judicially developed private...

A New Angle on Ground-Water Remediation
When engineers from Black & Veatch Waste Science (BVWS) went to Tinker Air Force Base to examine the site of a hazardous waste cleanup job the service had hired them for, they...

Intelligent Tutoring Systems to Aid Water Treatment Plant Operators
Training for water treatment plant operators exists primarily through short courses at colleges or technical schools, self-study manuals, and on-the-job training. Intelligent tutoring...

Estimating Clay Liner and Cover Permeability Using Computational Neural Networks
The ability to provide a quick estimate of the permeability value to be expected in laboratory testing (of field samples) would help to predict potential problems in meeting the permeability...

Computer Applications in Liquefaction Analysis
This paper discusses the applications of total and effective stress based computer programs for liquefaction analysis. A total stress based computer program, SHAKE in conjunction with...

Design of Clay Liner Permeability at Laboratory Scale Using Expert Systems
Unlike other soil properties, permeability of compacted clay is highly variable. The large number of parameters that affect permeability of compacted clay renders permeability unpredictable...

An International Knowledge Database for Ground Improvement Geo-Systems
Ground improvement technologies have traditionally played an integral and important role in major geotechnical construction projects throughout the history of civil engineering and selection...

Risk-Based Management of Uncertainty During Project Planning and Execution
The Land Disposal Restrictions (LDRs) of the Resource Conservation and Recovery Act (RCRA) are the critical technical standards for the establishment of compliance plans and schedules...

Computerized Facility Information Management Systems
The paper describes a computerized information system that can be used in place of the traditional operations and maintenance manual used by facilities personnel. Plant operations and...

Quality Management of Earthwork Using Knowledge-based Systems
Earthwork is an integral part of many construction projects. It involves cleaning of the site, loading and spreading of soil, and soil compaction and leveling. Heterogeneous orientation...

Use of Expert Systems in Selecting Equilibrium Isotherms of Organic Compound Adsorption on Activated Carbon
An outline of an Expert System (ES) that aids in selecting adsorption isotherms is presented. Such an ES provides an efficient technique for screening the present literature. The ES helps...

A Computational Algorithm for Analysis of Rectangular Footings Under Partial Contact with Soil
This paper describes a method to determine the distribution of base pressures under a rectangular footing experiencing partial contact of the footing with soil. Assuming the footing to...

A User Friendly Microcomputer Program for Liquefaction Potential Analysis
A user friendly microcomputer program is introduced to predict earthquake induced liquefaction and its associated settlement for level ground sites....

A Technique to Perform Coupled Consolidation Analysis Using Two Independent Softwares
The consolidation of soils involves two interdependent processes. These are fluid (air and water) flows and the deformation of the soil structure. The two processes tend to be treated...

Analysis of Port Allen Lock in Elastic-Plastic Soil Medium
Incremental finite element analyses using Drucker-Prager plasticity model are applied to study the interaction of Port Allen Lock with its surrounding soil. The analyses not only consider...

Discrete Modeling of Soil-Structure Interaction Under Dynamic Loading
A proposal of discrete modeling useful to describe behavior of structures burried in the ground under air explosion is presented. In the modeling emphasis is laid on determining the space...

Estimating Sediment Relative Density Using an Impact Core Sampler and Wave Equation-based Pile Analysis
This paper presents a case history in which soil sample drive resistance was modeled with a wave equation-based pile analysis computer program to estimate in situ sediment relative densities...
