Dr. A.K. Rastogi’s book on Numerical Groundwater Hydrology is prepared upon his teaching experience over the past twenty-four years of subjects related to groundwater hydraulics. This book provides an accurate and deep understanding of the numerical aspect of groundwater hydrology and helps the students to solve the numerical problems. Numerical problems test the understanding of concepts much better than theoretical problems. This book adeptly fill the vacant space of a standard book focusing on numerical problems of groundwater hydraulics (also referred to as fluid dynamics)
