Über dieses Buch

This book presents the basics of linear and nonlinear optimization analysis for both single and multi-objective problems in hydrosystem engineering. The book includes several examples with various levels of complexity in different fields of water resources engineering. The examples are solved step by step to assist the reader and to make it easier to understand the concepts. In addition, the latest tools and methods are presented to help students, researchers, engineers and water managers to properly conceptualize and formulate resource allocation problems, and to deal with the complexity of constraints in water demand and available supplies in an appropriate way.

Chapter 1. Importance of Optimization Analysis
Abstract
This introductory chapter introduces the challenges that the water professionals will encounter in water management and allocation of water supply, factors that impact the water availability, water-energy-climate change relationships, water transfer and the role of various stakeholders, and finally policy decisions deriving the investments needs for planning and maintaining water supply systems.

Chapter 2. Linear Optimization
Abstract
The purpose of this chapter is to cover the basic concept of linear optimization analysis and its applications in water resources engineering. The graphical and simplex solution methods for solving linear optimization problems are illustrated step by step. In addition, the applications of simplex method in solving water distribution network and one and two dimensional confined aquifer optimization problems using the Solver tool in Excel are presented.

Chapter 3. Nonlinear Optimization
Abstract
This chapter begins with an introduction to nonlinear programming and continues with introducing the conceptual framework of nonlinear optimization problems as well as their applications in water resources engineering. In addition, different nonlinear optimization methods including one-dimensional optimization techniques, unconstrained and constrained optimization methods in conjunction with a number of useful examples are provided to indicate why and how nonlinearities arise in wide ranges of water resources optimization problems.

Chapter 4. Multiobjective Optimization
Abstract
Many real-world problems require multiobjective evaluation that involves several minimizing or maximizing objective functions to be optimized simultaneously. In the case of multiobjective problems, a set of optimal solutions instead of a single solution will be determined. This chapter provides a basic introduction to the application of multiobjective optimization in water resources engineering and also provides a number of useful and applicable examples to better understand the concept of multiobjective optimization.

Chapter 5. Optimization Analysis Using LINGO and MATLAB
Abstract
LINGO and MATLAB are two of the well-known computer programs and powerful languages used today for expressing optimization models. In this chapter, the process of solving both single and multiobjective optimization problems using those programs is presented in details. Furthermore, a number of useful examples are provided and solved step by step to better understand the application of LINGO and MATLAB in solving linear and nonlinear optimization problems.

Chapter 6. Reservoir Optimization and Simulation Modeling: A Case Study
Abstract
This chapter presents a combination of optimization (LINGO) and simulation (HEC-ReSim) models to determine monthly operating rules for the Zayandehrud reservoir system in Iran. Based on the optimized flow determined in the single-objective framework, system behavior was simulated over 47 years. The results show that optimizing the operation of Zayandehrud reservoir could increase its storage by 88.9 % as well as increase the reliability index of regulated water for all downstream demands by more than 10 %.

Chapter 7. Reservoir Operation Management by Optimization and Stochastic Simulation: A Case Study
Abstract
Population increase and socio-economic mobility has escalated the water demand for various purposes and has put stress on existing water resources across the world, in particular in arid and semi-arid regions. Hence, managing the optimum use of water resources is a crucial issue and it is imperative to adopt realistic policies to ensure water is used more efficiently in various sectors. This chapter presents an optimization analysis to determine monthly operating rules for the Doroudzan Reservoir located in southern Iran. Different strategies under limited water availability conditions have been analyzed by running an optimization model based on observed and synthetic inflow data, and the performance indicators of each strategy are presented. Each strategy includes a minimum requirement release in the optimization process and results in a specific operation policy. In this study, LINGO is applied to determine optimum operational parameters and the synthetic inflows are generated using the Monte Carlo simulation method. The results demonstrated that the applied methods could efficiently optimize the current operational policy of an existing reservoir in a single-objective framework.

Chapter 8. Using Optimization in Wellfield Operations: An Implementation Case Study at Tampa Bay Water
Abstract
This chapter includes simulation–optimization analysis of water supply in central Florida using integrated surface and groundwater modeling to allocate groundwater pumping that is protective of the natural ecosystem while meeting water supply demands of over 2 million people using a mix of surface water, groundwater and desalinated water.
