Summary

The USGS in cooperation with the Trinity River Restoration Program, a multi-agency tasked with implementing federally mandated restoration, completed a geomorphic change assessment to inform the planning process for future restoration work. The ARCMAP geodatabase (v.10.0) contains geomorphic features digitized from six rectified orthophotographs (1980, 1997, 2001, 2006, 2009, and 2011). The structure of the geodatabase and methods used to delineate individual geomorphic features are described in Curtis, J.A., and Guerrero, T.M., 2015, Geomorphic mapping to support river restoration on the Trinity River downstream from Lewiston Dam, California, 1980–2011: U.S. Geological Survey Open-File Report 2015-5046, x p
