Groundwater flow induced collapse and flooding in Noctis Labyrinthus, Mars

Catastrophic floods of enormous proportions are thought to have played a major role in the excavation of some of the Solar System s largest channels; the circum-Chryse outflow channels. The generation of the floods has been attributed to both the evacuation of regional highland aquifers and ancient paleo-lakes. Numerous investigators indicate that these source regions were likely recharged and pressurized by eastward groundwater flow via conduits extending thousands of kilometers from an elevated groundwater table in the ...
