Numerical solutions of electromagnetic field problems is an area of paramount interest in academia, industry and government. This book provides a compendium of solution techniques dealing with integral equations arising in electromagnetic field problems in time and frequency domains. Written by leading researchers in the field, it documents the authors' unique space/time separation approach using Laguerre polynomials. Numerous examples that illustrate the various methodologies and user-friendly computer codes make this volume highly accessible for engineers, researchers, and scientists.

This book demonstrates, through concrete examples, the potential of isotope techniques in the development and management of water resources. It commences with a description of the characteristics of isotopes and their utility as tracers in studies pertaining to various stages of the hydrological cycle. The book delves into the usage of both environmental isotopes and injected tracers in surface water and groundwater bodies, as well as the relationships between them. Special emphasis is placed on the application of isotopes in identifying groundwater recharge and the processes associated with it, given its significance. The role of isotopes in understanding groundwater contamination caused by natural pollutants such as inland salinity, arsenic, and nitrate is also discussed with the aid of examples.
