Reduced-Complexity Model of Delta Formation
CSDMS awarded the 2011 Student Modeler Award to Man Liang, of St Anthony Falls Laboratory, University of Minnesota. She developed a reduced-complexity model for delta formation, which mimics channel migration, bifurcation and avulsion. The model combines a more detailed hydro-dynamics solver with a cellular model that routes water and sediment packages over a river and delta plain. Simulated delta evolution and geometry compare well with mappings of natural deltas. More...

Elwha River restoration, the largest dam removal project in North America
In the 20 years since the U.S. Congress passed a law ordering its removal to allow salmon restoration, scientists have conducted intensive studies of the river and coastal system in its current sediment starved state. They have tried to predict the impact of sediment releases during and after dam removal. Gelfenbaum et al., 2009 used Delft-3D to estimate how sediment releases from the dams will impact coastal sediment dynamics and supply to the river’s delta and nearby beaches.More...
