Special Hydraulic Problems Related to Coastal Louisiana Drainage Systems
The urbanized coastal areas of southeast Louisiana present unique problems for hydraulic engineers. These problems relate to the design of drainage systems serving leveed areas with flat...

Retention of the First Inch of Runoff in Coastal Areas
More and more state agencies are requiring development to retain the first inch of runoff from impervious coverage and release this runoff only through evaporation and/or infiltration....

Stochastic Modeling of Groundwater Contamination?A Distributed Parameter Kalman Filtering Approach
Stochastic methods are applied to the analysis and prediction of large scale solute transport in saturated heterogeneous porous media. An extended distributed parameter Kalman Filter which...

Geostatistical Global Estimates and Sampling Design
In the environmental assessment of a contaminated site, several different evaluation criteria could be considered such as: estimation of the overall average contaminant concentration in...

Geostatistics in Estimating Chemical Residuals at a Site
Kriging with generalized covariances is used to evaluate the effectiveness of remediation and cleaning of a contaminated site. The goal is to estimate: a) the amount of total volatile...

Technical Considerations in Numerical Modeling of Pressure Reducing Valves in Water Distribution Systems
In large water distribution networks, pressure reducing valves (PRVs) are common water appurtenances. However, there are difficulties in representing them when using the Hazen-Williams...

Water Distribution System Design Considering Component Failure During Static Conditions
A continuous hydraulic availability relationship is presented which more realistically models minimum pressure requirements for water distribution systems. This relationship is used in...

Redundancy and Reliability of Water Distribution Networks: An Entropy Based Approach
Based on the concepts of entropy and graph theory, a functional form is developed as a quantitative measure for redundancy in water distribution networks. This function was obtained by...

Optimal Reliability Based Design for Water Distribution Systems
The methodology presented in this paper explicitly includes availability measures that incorporate both mechanical and hydraulic unavailability of system components for a dynamic system....

A Synthetic Simulation Model of Storm Surge History and Inland Drainage in Coastal Zone Areas
In this paper, a synthetic storm surge model is proposed. With the input information of peak surge height, storm duration, and shape coefficients, this model is capable of simulating most...

Drainage Problems in a Highly-Developed Shoreline Area
Hilton Head Island, South Carolina, is a 42-square mile barrier island on the south-east coast Flooding of roads and properties is a continual problem in this low-lying, flat area due...
