This data release presents observations of riparian vegetation, topography, sediment quality, and river corridor geomorphology in four river reaches of the Lower Virgin River extending downstream 62 river kilometers (rkm) from near the town of Littlefield (AZ) and the Arizona-Nevada border at rkm 119. Methods included field observations and analysis of remotely-sensed data before (2010) and after (2011-2012) a 40-year return period flood (December 2010, at the gaging station “Virgin River near Littlefield” (USGS gage #09415000)). The data release includes four .csv files related to field observations: UTM coordinates of field transect locations; vegetation and geomorphology; species codes; and sediment quality....

Plant composition, geomorphic conditions and sediment properties before (2010) and after (2012) a 40 year return period flood (December 2010) at multiple transects within four reaches in the lower Virgin River, Nevada. The data contains four .csv files: localization (UTM coordinates of the transects), vegetation and geomorphology, species codes and sediment quality
