Field Investigation On Point Bar Dynamics And Planform Evolution In Meandering Rivers, Taylor Rowley

LSU Doctoral Dissertations

Point bars are prominent features in meandering rivers, yet our understanding of the complex interactions among channel morphology, three-dimensional flow structure, and depositional processes associated with modern and active point bars remains incomplete. Thus, the goal of this research is to characterize the morphology, three-dimensional flow structure, and depositional packages associated with point bars along a series of bends with different curvature and channel planform through detailed field measurements and relate to previous literature and current conceptual models.

Chapter 3 investigates the morphology of point bars by comparing estimates of channel curvature to channel and point bar characteristics including width, …
