tended to provide guidance to policy and decision makers. It is intended to
isolate the economic effects of interrelated factors of water quantity and
quality more explicitly to the end that water resources planning may more
effectively and efficiently serve the needs of society. Probably one of the
major flaws in the systems approach to water resources development is the
inability of the scientist and engineer to provide the political decision
makers with meaningful plans. It is hoped that this monograph will assist
them in their task in the future.
The authors gratefully acknowledge the assistance of Professor William
Lesso and Mr. James Lindsay in connection with the development of the
computer programs used in this monograph. The work upon which this
publication is based was supported by funds provided by the United States
Department of the Interior as authorized under the Water Resources
Research Act of 1964 as amended. D. T. O'Laoghaire would also like to
express his appreciation to The Institute for Industrial Research and
Standards, Dublin, Ireland, for financial support and to Dean Hermes
Espinoza Sosa of the Universidad de los Andes, Morida, Venezuela, for
arranging for him to have sufficient time for writing the book.
