| NCED receives National Science Foundation renewal | | The National Center for Earth-surface Dynamics (NCED) will continue its research on the processes that sculpt Earth's surface with the renewal of its National Science Foundation grant. The Center, consisting of 10 partner institutions from around the country, begins its second five-year term on August 1, 2007. According to NCED Director Chris Paola, "If you put biology together with physical, chemical, and social processes, you can predict how Earth's surface will respond to change and evolve over time. Therefore, we're delighted that NCED will be able to continue its integrative work in support of a sustainable surface environment." |  | | Left photo: NCED principal investigators and staff on a Mississippi Delta field trip.

| NCED transport and sorting models incorporated into HEC-RAS | | The US Army Corps of Engineers released version 4.0 of the Hydrologic Engineering Centers River Analysis System (HEC-RAS) software system containing advanced sediment transport and sorting functionality. This system includes the Wilcock/Crowe surface-based sediment transport model and the Toro-Escobar/Cui/Parker/Paola active layer sorting model. The HEC-RAS system is comprised of four river analysis components, including sediment transport/movable boundary computations, and is the industry standard model for 1d hydraulic modeling and sediment transport calculations. | | |
