The primary goal of this project was to understand the relative importance of the various sediment sources distributed throughout the Root River watershed, southeastern Minnesota, in order to inform future land and water management decisions. Specifically, the hypotheses to be tested were a) that the erosional history of the Root River watershed is highly variable, b) that a large amount of previously eroded sediment remains within the watershed as readily erodible legacy sediment, and lastly, c) that the dominant source of sediment to the Root River is this (non-field) legacy sediment currently being derived from floodplains and streambanks...
