Sediment Sources Associated with the Delaware and O’Shaughnessy Reservoirs, Ohio

Abstract Details

2008, Master of Arts, Miami University, Geography.
This study focuses on two Ohio reservoirs. The Delaware, with large increases in sedimentation rates in recent years and the O’Shaughnessy, with decreases. The questions I sought to answer were 1) what are the watersheds’ landscape/land use characteristics and have they changed, 2) is there evidence of recent channel enlargement, and 3) what are the sources of reservoir sediment? I examined impervious surfaces, developed area change, topography, soils, ditched streams, precipitation, and flooding. I found the watersheds are similar in most characteristics, but differ in flooding and channelized stream distribution. Channels are deeper and channel material is the dominant sediment source in the Delaware, while surface material is the dominant source in the O’Shaughnessy. Decreases in O’Shaughnessy sedimentation rates are likely due to improvement in agricultural practices and increased sedimentation in the Delaware is attributable to subtle differences in the watersheds; likely channelization plays an important role.
