Overview of the generated maps used for the erosion–accumulation simulation. The visualized area is the same as in Figure 2 and Figure 3 (18.48°N; 77.37°E). Note that the crater rim runs from top right toward lower left as a curved feature, while the delta structure is located at the middle of the four images. Inset (a): sediment size map (m); inset (b): flow width map (m); inset (c): flow velocity map (m/s); inset (d): calculated flow depth map (m). Please note that the calculated depth is only a model-based approach that should be further improved in the future. The coarse sand fraction grains are primarily located in the riverbed that flows into the Jezero Crater.
