A long-term study of the geomorphic history of the lower Rio Puerco arroyo in north-central New Mexico included the collection of high-precision (Real-time kinematic) GPS survey data, registration and rectification of historical aerial photographs, an aerial LiDAR survey, and acquisition of post-flood satellite imagery. Mapping of geomorphic features from the aerial photographs and satellite imagery began in 2002 and included channel banks, channel centerline, tops and bottoms of the arroyo walls, and shrub canopy cover. These data were used to determine spatial and temporal geomorphic change within the arroyo from 1935 2014 (Vincent et al., 2009; Perignon et al., 2013; Griffin et al., 2014; and Friedman et al., 2015) and to quantify the effects of woody vegetation on channel and floodplain flow and sediment transport (Griffin et al., 2005; Griffin et al., 2010; and Griffin et al., 2014). This GIS data collection includes: 1) shapefiles containing GPS survey data (April 2002, January 2007, April 2010, and April 2014) and geomorphic features mapped from imagery (1935, 1950s, 1970s, 1996, 2005, and 2006); 2) georeferenced aerial photographs (1935, 1950s, 1970s, 1996, and 2005); and 3) 2005 aerial LiDAR survey data and derived Digital Terrain Models (DTMs). High-resolution November and December 2006 Quickbird II satellite imagery (DigitalGlobe, Inc.), used for mapping post-2006 flood geomorphic features, is proprietary and, therefore, cannot be served here.
