About the Book

About The Book

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 fills the vacant space of a standard book focusing on numerical problems of groundwater hydraulics (also referred to as fluid dynamics).

Water security is a major concern of the 21st century because of its direct link with food security. Apart from agricultural needs, municipal expansion and increasing industrial requirements have led to an increased demand for water. Groundwater is an important resource and to meet these growing demands, it is used in many countries today. Therefore groundwater exploration, planning, and management will play an important role in the effective utilization of this precious resource. For this reason, groundwater hydrology will continue to be an important subject in almost all technical institutions for a very long time to come.

This book is written for Undergraduate and Postgraduate students of civil engineering, water resources engineering, environmental engineering, agriculture engineering and earth sciences. Those who are pursuing a degree or diploma course in the areas of Water Resources Management, Hydro-Geology, Geo-Hydrology and various centers of Environmental Science and Engineering will also find this book useful.

The chapters on inverse modeling, numerical modeling and solute transport will be useful reading for research scholars and scientists working on various boards dealing with groundwater and centers of water resources. The chapters dealing with groundwater flow and transport modeling will give students the necessary confidence to use different types of commercial software packages available on these areas.

Features:

  • Derivations of all important equations and solutions of important equations.
  • 146 solved numerical problems some on finite difference, finite element, solute transport modelling etc.
  • 100 questions and 98 numerical problems for exam paper setters.
  • 12 chapters with 431 figures and 1093 equations
