Model for Water Distribution System Reliability
Publisher: American Society of Civil Engineers
Abstract: The hydraulic reliability of a water distribution system can be defined as the probability that the system can provide the demanded flowrate at the required pressure head. Due to the random nature of future water demands, ...
Reliability Analysis of Pumping Systems
Publisher: American Society of Civil Engineers
Abstract: A new methodology is presented for the reliability analysis of pumping stations for water‐supply systems. The methodology considers both mechanical failure and hydraulic failure and models the available capacity of a pumping ...
Models for Water Reuse and Wastewater Planning
Publisher: American Society of Civil Engineers
Abstract: A planning model is developed for the determination of optimal water reuse allocation and wastewater treatment alternatives that minimizes the overall cost of water supply and wastewater treatment over a planning period. ...
Optimization of Freshwater Inflows to Lavaca‐Tres Palacios, Texas, Estuary
Publisher: American Society of Civil Engineers
Abstract: The companion paper by the writers developed a model for the determination of optimal freshwater inflows into bays and estuaries for the purpose of balancing freshwater demands with the various types of fish harvests. This ...
Goal Programming Models for Determining Freshwater Inflows to Estuaries
Publisher: American Society of Civil Engineers
Abstract: This paper presents two multiobjective models for the estuary‐management problem based upon goal‐programming procedures. The multiobjectives are the minimization of freshwater inflow into bays and estuaries and the ...
Differential Dynamic Programming for Estuarine Management
Publisher: American Society of Civil Engineers
Abstract: A differential dynamic programming (DDP) procedure is applied to solve both linear and nonlinear estuarine-management problems to determine the optimal amount of freshwater inflows into bays and estuaries to maximize fishery ...
Estuary Management by Stochastic Linear Quadratic Optimal Control
Publisher: American Society of Civil Engineers
Abstract: A new type of estuary-management model based on discrete-time stochastic linear quadratic optimal control is presented. It is a feedback-control model that enables decision makers to determine the upstream reservoir releases ...
Real-Time Operation of Water-Supply Canal Systems under Limited Electrical Power and/or Water Availability
Publisher: ASCE
Abstract: Water-supply systems (WSSs) and electrical power systems (EPSs) are highly interdependent critical infrastructures. The electrical energy required for pumping in WSSs and cooling water required for power plants in EPSs are ...
Uncertainty and Risk Analyses for FEMA Alluvial-Fan Method
Publisher: American Society of Civil Engineers
Abstract: Alluvial fans along mountain bases pose quite interesting problems for the design of hydraulic structures and highway crossings and for flood insurance studies. The Federal Emergency Management Agency (FEMA) alluvial-fan ...
New Methodology for Optimization of Freshwater Inflows to Estuaries
Publisher: American Society of Civil Engineers
Abstract: The objective of this work is to develop a general methodology for determination of the optimal freshwater inflows into bays and estuaries to balance freshwater demands with the harvest of various types of estuarine ...
