Analytical Solutions of Geohydrological Problems

This book has been divided into two parts, A and B.
Part A comprises analytical solutions of about 1100 geohydrological problems in the saturated zone. Classification of the problems according to certain characteristics.
Part B consists of three chapters, describing the basic principles for saturated ground water flow, analytical solution methods and mathematical functions respectively.
