The study bolsters the idea that Mars once had a warmer climate and active hydrologic cycle, with water evaporating from an ancient ocean, returning to the surface as rainfall and eroding the planet's extensive network of valleys.

While the illustrative example focuses on the flooding hazard, the methodology can be applied to other extreme hydrologic events, such as hurricanes and tsunamis.

This study highlights the key role of vegetation in controlling future terrestrial hydrologic response and emphasizes that the continental carbon and water cycles are intimately coupled over land and must be studied as an interconnected system.

It is commonly thought that hydrologic change is driven by precipitation and radiation changes caused by climate change, and that as the land surface adjusts, rising temperatures and lower precipitation will make the planet drier.
