There is much evidence that liquid water once flowed on the surface of early Mars. Preserved ancient landscapes altered by water provide valuable insight into the past processes on Mars, the presence of water, past environmental conditions, and habitability. To better understand the fluvial geomorphology on Mars, we use knowledge from systems on Earth. However, is it fair to do so when gravity is much lower? How does gravity affect sediment transport? And how does this, in turn, influence the morphology and stratigraphy on Mars? In this talk, I will clarify the effect of gravity on fluvial sediment transport with analytical modelling and use numerical modelling to show the effect of gravity on delta morphology.
