Cost surfaces combining landscape elevational connectivity, distance to the main river and local slope are used to compute current flow fields35. Current flow values are then standardised at each time step by calculating z-scores to evaluate temporal changes in landscape connectivity across the different maps. Positive z-scores (red to yellow) represent high connectivity areas acting as preferential pathways across the Sunda Shelf.
