The spatial distribution of fluvial and limnic sediments data provided new insights into the evolution of these conflu- ences expanding into the Salzburg Basin, Bad Reichenhall and Piding basins after the Last Glacial Maximum._________________ The two rivers deposited their coarse sediments in the basin, producing delta fans that subsequently progressed towards the basin center, leaving behind beds of coarse-grained sediments in the otherwise fine-grained lake deposits.
