Characterizing The Hydrodynamics Of A Meandering River Neck Cutoff, Christopher Turnipseed

LSU Master's Theses

Meandering river systems often experience a geomorphic phenomenon known as a neck cutoff. The White River of Arkansas has recently undergone several neck cut offs, which have provided a unique opportunity to collect field measurements of the first two years after the opening of the cutoff. In this study the field data was complemented with hydrodynamic simulations to assess the significance of different flow conditions. The findings suggest that flood events play a substantial role in the geomorphic adjustment of the river to the cutoff.
