A mathematical morphology contributions to study some aspects of hydrogeological systems

Abstract:

In order to study groundwater flow and contaminant transport it is important to model the aquifer heterogeneities in terms of the spatial distribution of its hydrostratigraphic units. These units can vary strongly in thickness and can also be geometrically anisotropic and present different features concerning their neighbourhood relationships. In this paper a contribution of mathematical morphology is presented to study several aspects of hydrogeological systems, namely to create regular bodies, to identify flow paths in media and to establish a graph of vicinity relationships between hydrostratigraphic units. The developed methodologies are tested on a real case study in the aquifer system of Tejo river. © 2001 Published by Elsevier Science Ltd.
