During my academic career as a professor and in conviction of my personal life I have received help and encouragement from so many people that it is not possible to name them all. To all of you I express my deepest thanks. There were a few including some colleagues and former students that have tried to stop or discourage me. I am grateful to them too because without them I could not be so determined to improvise. Water Resources system analysis has been a part of a personal journey that began years ago when I was a young boy with a love of water. Books are companions along the journey of learning and I hope that you will be able to use this book in your own exploration of the ¿eld of water resources. Have a wonderful journey.
