Processes in Karst Systems - Dreybrodt, Wolfgang

. .

Résumé :
Karst Systems deal with the question of how the subsurface drainage system, typical of Karst areas develops from its initial state to maturity. Equal attention is given to physical, chemical and geological conditions which determine karstification. The reader will find discussions of mass transport, chemical kinetics, hydrodynamics of fluxes, and the role of dissolution and precipitation of Calcite as they occur in experiments and natural environments. It offers a wealth of information on a complex natural system to hydrologists, hydrochemists, geologists and geographers.
