PhD Student Aaron Zettler-Mann has received a Doctoral Dissertation Improvement Grant from the National Science Foundation. Aaron’s dissertation is entitled “Lateral Channel Confinement and its Impact on Channel Morphology”, and this grant (for $15,912) will allow Aaron to conduct fieldwork and analysis of the Rogue River and the influence of lateral sediment supply on channel morphology. Aaron has extensive experience on extracting 3D data and orthophotographs from imagery, and these skills will allow him to produce sediment maps throughout the river system through automated feature extraction from imagery techniques. Aaron hopes to test the applicability of the sediment links theory concept to the Rogue River and extend the concept to sediment sources from hillslopes in addition to the traditional tributary sources. Aaron’s advisor is Mark Fonstad.
