Summary

These data include geospatial files (shapefiles and orthorectified raster images) and an input hydrograph (csv) for a 1-dimensional unsteady hydrologic model. Shapefiles consist of active channel boundarys and channel centerlines of six reaches of the LCR beginning ~4.5 km above Grand Falls, AZ, and ending ~12.8 km downstream from Cameron, AZ. These reaches are (1) the ~4.5 km above Grand Falls reach, (2) the 1.5km below Grand Falls reach, (3) the ~18.8 km Black Falls reach, (4) the ~16.5 km above Cameron reach, (5) the ~4.7 km Cameron to Moenkopi reach, and (6) the ~8.1 km below Moenkopi reach. Raster images consist of orthorectified aerial photograph mosaics between 1933/34 and 1992. Scans of the images were acquired from either [...]

Purpose

Aerial imagery was orthorectified and mosaicked by Pinnacle Mapping Technologies in Flagstaff, AZ such that active channel boundaries and channel centerlines could be delineated. Shapefiles of active channel boundaries and channel centerlines were used to calculate changes in active channel width over time. The input hydrograph for the hydrologic modeling was used to investigate how flood travel time and hydrograph shape changed over time as channel narrowing and vegetation colonization of floodplains occurred.
