Neural Networks and Reinforcement Learning in Control of Water Systems
(American Society of Civil Engineers, 2003)In dynamic real-time control (RTC) of regional water systems, a multicriteria optimization problem has to be solved to determine the optimal control strategy. Nonlinear and/or dynamic programming based on simulation models ... -

Optimal Scheduling of Multiple Chlorine Sources in Water Distribution Systems
(American Society of Civil Engineers, 2003)The specified range of free chlorine residual (between minimum and maximum) in water distribution systems needs to be maintained to avoid deterioration of the microbial quality of water, control taste and/or odor problems, ... -

Projected Sulfate Redistribution As Impacted by Lake Level Stabilization Scenarios: Devils Lake, North Dakota
(American Society of Civil Engineers, 2003)Devils Lake, a terminal, saline lake, of glacial origin, in North Dakota has experienced a 7.5 m rise in lake elevation resulting in the flooding of over -
Implications of Applying Statistically Based Procedures for Water Quality Assessment
(American Society of Civil Engineers, 2003)Assessment of water quality conditions as required by Section 303d of the Clean Water Act must rely on limited monitoring data. Because data are limited there will always be the potential for error when deciding if water ... -
A <i>CE-QUAL-W2</i> Model of Neuse Estuary for Total Maximum Daily Load Development
(American Society of Civil Engineers, 2003)In support of a total maximum daily load (TMDL) analysis, hydrodynamic and water quality conditions in the Neuse River Estuary were simulated for a 43 month period beginning in June 1996 using the two-dimensional, laterally ... -
Consideration of Variability and Uncertainty in Phosphorus Total Maximum Daily Loads for Lakes
(American Society of Civil Engineers, 2003)A simplified framework for considering variability and uncertainty in developing lake phosphorus total maximum daily loads (TMDLs) is demonstrated. Explicit consideration of these factors can increase the probability that ... -
Integrated Approach to Total Maximum Daily Load Development for Neuse River Estuary using Bayesian Probability Network Model (Neu-BERN)
(American Society of Civil Engineers, 2003)We develop a probability network model to characterize eutrophication in the Neuse River Estuary, North Carolina, and support the estimation of a total maximum daily load (TMDL) for nitrogen. Unlike conventional simulation ... -
Is It Time to Resurrect the Harvard Water Program?

Support of Total Maximum Daily Load Programs Using Spatially Referenced Regression Models
(American Society of Civil Engineers, 2003)The spatially referenced regressions on watershed attributes modeling approach, as applied to predictions of total nitrogen flux in three North Carolina river basins, addresses several information needs identified by a ... -
Optimizing Urban Water Supply Headworks Using Probabilistic Search Methods
(American Society of Civil Engineers, 2003)Simulation models in conjunction with synthetic multiple hydro-climate replicates provide the most realistic assessment of the performance of urban water supply headworks systems. However, optimization using such models ... -
Dynamic Optimal Unit Commitment and Loading in Hydropower Systems
(American Society of Civil Engineers, 2003)The hydropower unit commitment and loading problem represents a complex decision-making process involving the integrated hourly scheduling of generators in a multiproject hydropower system. Optimal scheduling maximizes ... -
Comparison of Estuarine Water Quality Models for Total Maximum Daily Load Development in Neuse River Estuary
(American Society of Civil Engineers, 2003)The North Carolina Division of Water Quality developed a total maximum daily load (TMDL) to reduce nitrogen inputs into the Neuse River Estuary to address the problem of repeated violations of the ambient chlorophyll -
Development of Three-Dimensional Hydrodynamic and Water Quality Models to Support Total Maximum Daily Load Decision Process for the Neuse River Estuary, North Carolina
(American Society of Civil Engineers, 2003)The Neuse River Estuary was included on the North Carolina Department of Water Quality 303(d) list for nutrients, and was scheduled for total maximum daily load (TMDL) development by spring of 2001. The water quality target ... -
Coping with Uncertainty: A Case Study in Sediment Transport and Nutrient Load Analysis
(American Society of Civil Engineers, 2003)We present a computational approach for identifying the significance of uncertainty in assessing the consequences of sediment and nutrient transport in a section of the Chattahoochee River south of Lake Lanier, as it passes ... -
Methodology for Assessment of Climate Change Impacts on Large-Scale Flood Protection System
(American Society of Civil Engineers, 2003)An original modeling framework for the assessment of climate variation and change impacts on the performance of a complex flood protection system has been developed for the city of Winnipeg in the Red River basin, Manitoba, ... -
Optimal Pump Scheduling in Water Supply Systems with Maximum Demand Charges
(American Society of Civil Engineers, 2003)The calculation of optimized pump schedules is sometimes complicated by the inclusion of a maximum demand charge in the electricity tariff. Maximum demand charges can be as much as 35% of energy costs, and in the United ... -
Performance, Cost, and Maintenance Requirements of Austin Sand Filters
