In this book, there is a departure from empiricism and the emphasis is on the collection of data and analysis of the hydrological factors involved and promote hydrological design on sound principles and understanding of the science, for conservation and utilisation of water resources. Hydrological designs may be made by deterministic, probabilistic and stochastic approaches but what is more important is a matured judgement to understand and avoid what is termed as unusual meteorological combination.

This book introduces to the reader all aspects of ground water i.e., its assessment, development, utilisation and management. Practical application of different formulate for field conditions, data collection and processing, test procedures and principles of design are worked out to illustrate the theory and design procedure. It includes case studies of pump test data in the country. Methods of irrigation and complete design and layout of sprinkler and drip irrigation projects are given.
