Monitoring Rates of Change in Maine Rivers

Presentation not available.

Aaron Corr, Parish Geomorphic, Fredericton, New Brunswick, 506/472-8440

The rate at which the physical properties of rivers change is of particular value to the management, planning and restoration of rivers. Changes can include migration of meanders, erosion of banks, widening, development of bars, and degradation or aggradation of bed levels. Rates of change are determined from historical analysis of aerial photos and maps, as well as from yearly monitoring of the form and process at monumented locations. Rate of change information can be used to help set corridor widths for land conservation, for the development of management plans, and for establishing appropriate restoration priorities and goals. A summary of historical analyses and monitoring data for 10 Maine rivers is presented and compared to other regional relations and models of rates of change. Interpretation of the data and implications to management and restoration of Maine rivers will be presented. Sincerely, Aaron Corr Parish Geomorphoc, Ltd.
