Planning and management of water resources and its optimal use are a matter of urgency for most countries of the world, and even more so for India with a huge population. Growing population and expanding economic activities exert increasing demands on water for varied needs--domestic, industrial, agricultural, power generation, navigation, recreation, etc. In India, agriculture is the highest user of water. The past three decades have witnessed numerous advances as well as have presented intriguing challenges and exciting opportunities in hydrology and water resources. Compounding them has been the growing environmental consciousness. Nowhere are these challenges more apparent than in India. As we approach the twenty first century, it is entirely fitting to take stock of what has been accomplished and what remains to be accomplished, and what accomplishments are relevant, with particular reference to Indian conditions. India has had a long tradition of excellence spanning over several millennia in construction of water resources projects. She has produced civil engineers of highest quality, some of whom rank among the best in the world. In keeping with India's tradition of honoring distinguished engineers at their retirement, it was decided to hold an International Conference on Hydrology and Water Resources, December 20-22, 1993, in New Delhi, to celebrate the retirement of Professor Satish Chandra, Director of the National Institute of Hydrology at Roorkee, who has had a long and distinguished career spanning over three decades in hydrologic education, research, and development. Through this forum, it was hoped to bring together from all over the world researchers, educationists, and practitioners to New Delhi, India, to present the results of their latest work, to share their experiences, to interact with Indian water resources professionals, and to, hopefully, set the stage for future course of hydrology and water resources. The objectives of this conference were therefore (I) to assess the current state of the art of hydrology and water resources, (2) to discuss applicability of hydrologic and water resources models, (3) to enhance interdisciplinary interaction, (4) to discuss research needs in hydrology and water resources, and (5) to determine the directions for further research. We received an overwhelming response to our call for papers. The subject matter of the conference was divided into 36 major topics encompassing virtually all facets of hydrology and water resources. Each topic comprised an invited state-of-the-paper and a number of contributed papers. These contributions provided a natural blend to evolve a synthesized body of knowledge on that topic. Extended abstracts of all the invited and contributed papers were assembled in a pre-conference proceedings volume. This helped stimulate discussion and exchange of ideas during the conference. The papers presented at the conference were reviewed by the Organizing Committee. As a result, some of the papers did not pass the review and were therefore eliminated from inclusion in the final proceedings. The papers contained in this book, SUBSURFACE-WATER HYDROLOGY, represent one part of the conference xi xii contributions. The other parts are embodied in three separate companion books, SURFACE-WATER HYDROLOGY, WATER-QUALITY HYDROLOGY, and WATER RESOURCES PLANNING AND MANAGEMENT, which are being published simultaneously. Arrangement of the contributions in these books under four different titles was a natural consequence of the diversity of topics presented in the papers. These books can be treated almost independently, although some overlap may exist between them. This book contains five sections encompassing major aspects of subsurface-water hydrology. Each section usually starts with invited state-of-the-art papers, followed by contributed papers. Beginning with unsaturated flow in the first section, the papers go on to discuss seepage and drainage in Section 2, groundwater recharge in Section 3, aquifer response in Section 4, and groundwater resource evaluation in the concluding Section 5. The book will be of interest to researchers as well as those engaged in practice of Civil Engineering, Agricultural Engineering, Hydrology, Water Resources, Earth Resources, Forestry, and Environmental Sciences. The graduate students as well as those wishing to conduct research in water resources planning and management will find this book to be of particular value. We wish to take this opportunity to express our sincere appreciation to all the members of the Organizing and Advisory Committees, the Louisiana State University administration, and the Indian Association of Hydrologists. Numerous other people contributed to the conference in one way or another, and a lack of space does not allow us to list all of them by name here. We would, nonetheless, like to single out Mr. S. S. Kanwar, who served as Assistant Conference Organizing Secretary, for his inordinate assistance and effort without which the conference would not have come to fruition. Numerous other people contributed to the conference to varying degrees. The authors, including the invited keynote speakers, contributed to the conference technically and made the conference what it was; and this book is largely a result of their efforts. The session chairmen/co-chairmen administered the sessions in a positive and professional manner. We owe our sincere gratitude to all of these individuals. If the success of a conference is measured in terms of the quality of participants and presentations, then most people would agree that this was a very successful conference. A large number of internationally well-known people, who have long been recognized for their contributions and have long been at the forefront of hydrologic and water resources research, came to participate in the conference. More than 20 countries, covering five continents and most of the countries of the world active in research in hydrology and water resources, were represented. It is hoped that long and productive personal associations and friendships will develop as a result of this conference. V. P. Singh Conference Chairman B. Kumar Organizing Secretary
