Modeling Flow in Variably-Saturated Porous Media
An expression for effective hydraulic conductivity to solve groundwater flow problems is developed. Also, a refined Monte Carlo (MC) simulation procedure is proposed. The developed methodologies...

Considering Uncertainties in Water Resource Designs
Design of water resource systems often faces with various uncertainties. The nature of problems in essence are decision making under uncertainties. This paper offers an introduction to...

Recent Advances In Well Hydraulics
Most books and papers on well hydraulics are mostly or entirely aquifer hydraulics. The phrase, 'well hydraulics,' implies a study of the flow into and within a well proper. There has...

Potable Water Reclamation?A Practical Option to Traditional Sources
This paper describes the development of potable water reclamation alternatives to meet the future municipal water needs of the City of Colorado Springs, Colorado. By the year 2042, the...

Determining Optimal Parameter Dimensions for Water Distribution Network Models
Water distribution systems contain a large number of pipes whose roughness factors are unknown prior to model calibration. During the calibration process, pipe roughnesses for each link...

Tug Fork Flood Plain Modifications and Wetlands Mitigation
The West Virginia Department of Highways (WVDOH) is using a two stage channel excavation concept to mitigate the hydraulic impacts of relocating U.S. Route 119. The selected highway alignment...

Recommendations for Standards in Hydraulics

Utilizing Mathcad for Hydraulic Design of Stormwater Pump Stations
This paper describes how the software Mathcad was used for hydraulic design of three pump stations (i.e. select pumps and size forcemains). The pump stations are part of a complete stormwater...

SCADA System Controls Combined Sewer Overflow Regulation System to Optimize Wastewater Collection
The Metropolitan St. Louis Sewer District's Overflow Regulation System (ORS) project uses computer control of a wastewater collection system for the purpose of combined sewage overflow...

Using Knowledge Based Systems for Training the Young Engineer
A Knowledge Based System 'HYDOC' (Hydraulic Design of Open Channels) is presented as a means to capture the knowledge of evaluating an open channel design problem to help teach evaluating...

Performance of Oil Storage Tanks on Vibroflotation Improved Hydraulic Fill in the Port of Tampa, Florida
The paper describes a case history of design, construction and performance monitoring of two 80,000 barrel oil storage tank foundations 35 meters in diameter on a soft hydraulic fill soil...

Vacuum-Assisted Consolidation of a Hydraulic Landfill
As part of the Pier 300 42-acre site ground modification project, a field test of vacuum-assisted preconsolidation of hydraulic fill was studied. The objective of the test was to assess...

Methods for Risk and Reliability Analysis
Recently, there has been considerable emphasis on the state of decay in the nation's infrastructure because of its importance to society's needs and industrial growth. Water distribution...

Water Infrastructure Risk Ranking and Filtering Method
The availability of water distribution infrastructure is critical to the sustained support and growth of society. Water infrastructure consists of systems that carry water (pipe and irrigation...

Modeling Issues of Copper Solubility in Drinking Water
The paper discusses the application of a model to the solubility of copper in drinking water. This paper is the result of numerous forms of pitting corrosion and pipe failures. Monitoring...

Application of Numerical Models in the Design of Clarifiers
In this study, a numerical model of a circular clarifier was applied to reveal the effects of the water depth on the hydraulic and removal efficiency. The velocity and solids concentration...

Optimizing Secondary Clarifier Performance: A Presentation Outline
Optimizing secondary clarifier performance is an activity that involves a consideration of the design, the maintenance, and the operation of the clarifier. Although the basic shape of...

Optimization Studies of Anaerobic Expanded Bed Reactor Pretreatment of Domestic Wastewater
In recent years the advent of the anaerobic expanded bed reactor (AEBR) has made possible the treatment of wastewaters of comparatively lower strength than have traditionally been treated...
