Preface – Elementary Engineering Hydrology


I am very happy to present this book for the benefit of students and practising engineers.

I taught this subject for over 35 years and sincerely felt the necessity of a good textbook explaining the subject in a simple language making the fundamentals clear and also indicating its practical application. I have, therefore, made the text comprehensive and covered almost the entire gamut of related topics.

The sequence of the chapters followed in the book is similar to the processes of the hydrological cycle. Each chapter is divided into sub-topics, which will help to bring clarity to the subject matter and make it easy for students to grasp the concepts. A number of appendices are added to provide all the necessary allied information. The text includes a number of numerical problems with solutions to help clarify the concepts and demonstrate their practical utility. At the end of each chapter ‘multiple choice questions’ are given to help students prepare for competitive examinations.

A number of my students have helped me in writing this book. It is not possible for me to mention all the names here but I thank them all. The help and guidance extended by Professor P. R. Bhave, Dr C. D. Thatte, Professor S. Y. Kute and Professor R. D. Mahadeokar for checking the text and numerical problems is thankfully acknowledged. I also thank Vasant Vaze, my business partner, for all the help extended by him.

I have made a sincere attempt to make this book a valuable reference book. Any suggestions to enhance the quality of this book are welcome.
