Simulation of the evolution of maze caves.

Abstract:
The development of cave systems in carbonate rocks depends on a variety of boundary and initial conditions. Among the cave systems, two main types of geometries can be distinguished: the dendritic and maze pattern. A numerical model has been developed capable of modeling the genesis of karst systems in complex geological environments. It is applied to simulate the development of the above mentioned two different types of cave geometries. The results confirm that a prerequisite for the development of maze caves is evenly distributed recharge (White 1969). However more important for the development of maze caves is that flow through the system is restricted by an overlying less conductive horizon, e.g. a sandstone caprock. Thus the feed back mechanism of higher flow rates leading to higher dissolution rates and therefore the preferential development of a small number of tubes does not dominate the evolution of the karst aquifer. This hydraulic restriction furthers the development of other conduits also to achieve a significant diameter.
