Paper Summary

The way sediment is supplied in river models affects how dunes and bars form. When sediment is recirculated from the downstream end, dunes become taller and more dynamic. Bars stay similar in size but change shape over time. Using a specific sediment equation matches real-world observations better than using standard equations.
