The Evolutionary Concepts and Practical Utilization of the Tóthian Theory of Regional Groundwater Flow

Abstract

An attempt is made here to summarize the history and to highlight the major constituting concepts, properties and applications of the Tóthian Theory of Regional Groundwater Flow from its conception [1,2] to the mid 2010s. Regional, or basinal, groundwater flow is defined here as “the gravity-driven cross-formational motion of groundwater at spatial and temporal scales that are commensurate with dimensions of the natural topographic relief and with the human and geologic time spans, respectively. The general “umbrella” theory is made up of two component sub-theories, namely: 1)
