Abstract Details

2010, Master of Arts, Miami University, Geography.
Channel morphology is affected by land use change nationwide. In Southwest Ohio, streams are influenced by agricultural and urban landscapes. The purpose of this study was to determine how agricultural and urban landscapes alter the modern bankfull hydraulic geometry within five watersheds: Upper Four Mile Creek, Indian Creek, Harkers Run, Marshalls Branch and Bull Run. A combination of field and LiDAR data were used to determine the bankfull channel geometry. Recurrence intervals of bankfull hydrology were determined from Log-Pearson Type III distribution of peak annual discharges for two streams. Analysis shows that four out of the five streams have bankfull channels larger than expected based on hydrologic and regional indicators. However, Upper Four Mile Creek does not appear to have an enlarged channel, most likely a result of base level rise from downstream dam construction. Accurate identification of bankfull hydraulic geometry is essential for effective stream restoration and management projects.
