23 5.1 INTRODUCTION A large number of geographic features and geomorphic planform characteristics used in the evaluation of meander migration are readily discernible on aerial photographs and topographic maps. Thus, a comparison of many of these features and characteristics over time can be made to determine the rate and extent of historic changes and assess potential future changes.

in the record and provide a better basis for predicting meander migration by extrapolation. Abrupt changes in migration rate and major position shifts can be accounted for by analyzing maps and photos for land use changes, and nearby stream gauge records can be examined for extreme flow events.

25 GIS-based software (such as ArcView and ArcInfo) can be used in conjunction with a flatbed scanner and digitizing tablet to perform the photo comparisons with greater precision and accuracy, especially when the maps and photos are georeferenced.
