Rivers can threaten riverside communities through bank erosion, deposition, and flooding, necessitating a thorough understanding of the response of river channels to natural and anthropogenic forces. Therefore, spatial and temporal changes in channel geometry and migration of the Susquehanna River in the Binghamton (NY) region, from 1937 to 2002, were examined, and their possible causes were assessed. Channel migration was measured in a Geographic Information System (GIS) from aerial photographs taken nearly every decade since 1937. Additional information about the ages of depositional surfaces was gained by measuring the age of trees on these surfaces. At-a-station hydraulic geometry at the USGS gaging station at Conklin, NY, was analyzed for the years 1985 to the present using USGS records of channel geometry and flow. Changes in the channel cross-sectional geometry from 1971 to 1998 at the Conklin and Vestal USGS gaging stations were also analyzed. The results of a previously published analysis of hydraulic geometry changes at Conklin and Vestal for the years 1938 to 1985 were also considered.all errors at independent test points from each photo series, are also shown in Table 5. ... Also shown in Table 5 is the RMSE, and ground resolution for the same images used to create the cumulative frequency plots in Appendix 4. RMSE foranbsp;...
