They are responsible for losses amounting to billions of dollars and scores of deaths annually. Virtually all parts of the nation--coastal, moun tainous and rural--are affected by them. Two aspects of the problem of flooding that have long been topics of scientific inquiry are flood frequency and risk analyses. Many new, even improved, tech niques have recently been developed for performing these analyses. Nevertheless, actual experience points out that the frequency of say a 100-year flood, in lieu of being encountered on the average once in one hundred years, may be as little as once in 25 years. It is therefore appropriate to pause and ask where we are, where we are going and where we ought to be going with regard to the technology of flood frequency and risk analyses. One way to address these ques tions is to provide a forum where people from all quarters of the world can assemble, discuss and share their experience and expertise pertaining to flood frequency and risk analyses. This is what con stituted the motivation for organizing the International Symposium on Flood Frequency and Risk Analyses held May 14-17, 1986, at Louisiana State University, Baton Rouge, Louisiana. The objectives of this symposium were therefore (1) to assess the current state of the art of flood frequency and risk analyses, (2) to demonstrate applicability of flood frequency and risk models, (3) to establish complementary aspects of seemingly different models, (4) to enhance interdisciplinary interaction, (5) to discuss practice of flood frequency and risk analyses technology by federal agencies in the U.S., (6) to discuss research needs in frequency and risk analyses, and (7) to determine directions for further research. We received an overwhelming response to our call for papers. It was indeed a difficult task to select amongst the many excellent papers that were submitted, and we regret that we could not include all of them. The sole criterion for selection of a paper was its merit in relation to Symposium objectives. The subject matter of the Symposium was divided into 20 major topics encompassing virtually all facets of flood frequency and risk analyses. Each topic comprised of an invited state-of-the-art paper and a number of contributed papers. These contributions blended naturally to evolve a synthesized body of knowledge on that topic. Extended abstracts of all the invited and contributed papers were assembled in a pre-Symposium proceedings volume. This helped stimulate discussion and exchange of ideas during the Symposium. The papers presented at the Symposium were refereed in a manner similar to that employed for publishing a journal article. As a result, many papers did not pass the review and were therefore elimi nated from inclusion in the final proceedings. The papers contained in this book, FLOOD HYDROLOGY, represent one part of the Symposium v PREFACE contributions. The other parts are embodied in three separate books, HYDROLOGIC FREQUENCY MODELING, REGIONAL FLOOD FREQUENCY ANALYSIS, and APPLICATION OF FREQUENCY AND RISK IN WATER RESOURCES, which are being published simultaneously. Arrangement of these books under four dif ferent titles was a natural consequence of the diversity of technical material discussed in the papers. These books can be treated almost independently, although some overlap does exist between them. This book contains seven sections encompassing major hydrologic aspects of flood control and protection. Each section starts usually with an invited state-of-the-art paper, followed by contributed papers. Beginning with an assessment of hydrologic modeling and limitations, and a future flood research agenda for the United States, the papers go on to discuss hydrology of floods, urban and coastal flooding, streamflow simulation and forecasting, flood control and protection, and flood control programs. The book will of of interest to researchers as well as those engaged in practice of Civil Engineering, Agricultural Engineering, Hydrology, Water Resources, Earth Resources, Forestry and Environ mental Sciences. The graduate students as well as those wishing to conduct research in flood hydrology will find this book to be of particular value. I wish to take this opportunity to express my sincere apprecia tion to all the members of the Organizing and Advisory Committees, and the Louisiana State University administration for their generous and timely help in the organization of the Symposium. A lack of space does not allow me to list all of them by name here. Numerous other people contributed to the Symposium in one way or another. The authors, including the invited keynote speakers, contributed to the Symposium technically and this book is a result of their efforts. The session chairmen administered the sessions in a positive and professional manner. The referees took time out from their busy schedules and reviewed the papers. Graduate students assisted in smooth conduct of the sessions. lowe my sincere gratitude to all of these individuals. If the success of a Symposium is measured in terms of the quality of participants and presentations then most people would agree that this was a very successful Symposium. A very large number of internationally well-known people, who have long been recognized for their contributions and have long been at the forefront of hydrologic research, came to participate in the Symposium. More than 35 countries, covering the five continents and most of the countries of the world active in hydrologic research, were represented. It is hoped that long and productive personal associations will develop as a result of this Symposium. March 1987 Vijay P.
