Jeffrey Keck, Erkan Istanbulluoglu, Jessica Lundquist, Christina Bandaragoda, Kristin Jaeger, Guillaume S. Mauger, Alex Horner-Devine
2022, Water Resources Research (58)
Modeled stream discharge is often used to drive sediment transport models across channel networks. Because sediment transport varies non-linearly with flow rates, discharge modeled from daily total precipitation distributed evenly over 24-hrs may significantly underestimate actual bedload transport capacity. In this study, we assume bedload transport capacity determined from a...
