Abstract

Geomorphology, the study of classifying landforms, is the backbone of this project. This project addresses the geomorphological changes and the effect thereof on the Ashuelot River and the surrounding Keene area. The study focuses on three locations: East Surry Rd (south of Surry Dam), the old stone arch bridge on Court Street, and Gilsum Road (east of Shaw’s Corner, near the logging road crossing). The depth, velocity, and discharge of water were measured and calculated in addition to being mapped. In order to determine whether the Ashuelot River was eroding or depositing, the area was mapped, and the cutbanks and pointbars labeled. The maps revealed that the Ashuelot River is greatly affecting the Keene area and changing the geomorphology around it. This presentation will address the Ashuelot River’s migration to the west, the flooding history and erosion of the river, and the exposed historical artifacts in the river’s cutbanks.
