Geology incision floods fluvial geomorphology modeling basin hydrology hydraulic geometry The effects of basin hydrology on channel incision and hydraulic adjustments in mountain streams were studied using field data and models of watershed hydrology and channel hydraulics. Conventional theories predict similar channel geometries and hydraulics in the Cherry and Cranberry Rivers because they are adjacent and have similar geologies, climates, and hillslope processes. Unlike the Cherry River, the Cranberry does not conform to traditional ideas about bedrock river incision, which may be explained by its unusual trellis-like, highly elongated watershed morphology. Abrasion is the rate-limiting incision mechanism in the Cranberry because its trellis-like channel network geometry (CNG) causes hydrograph attenuation and comparatively low peak discharges; whereas, the dendritic Cherry River CNG favors plucking due to peaked hydrographs. Restricted flows in the Cranberry River cause downstream fining atop highly resistant sandstones, which maximizes abrasion potentials at the expense of competence. 2009-08-14 English text Ohio University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=ohiou1243871371 http://rave.ohiolink.edu/etdc/view?acc_num=ohiou1243871371 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
