Transcript – Coevolution of River-Channel Geomorphology and Riparian Vegetation on The Lower Brazos River, Texas

The goal of the study is to advance understanding on how scroll bars on Neander Bends perform and coevolved with riparian woody vegetation on the Grass River in Texas. Scrollbar is composed of ridges, eyes. Swails both encapsulate the evolutionary history of a low land meandering river by encoding the outcomes of the governing physical processes into the landscape. Scrollbar, formation and evolution are dominated by large magnitude floods, where the river flow overtops the banks and erodes the scrollbar as water rushes over the landscape. This is referred to as Skrull activation for the meander been presented. Our findings show that Skrull activation occurs within the range of the 80th to eighty fifth percentile flow as senior figure three. We also find that it is not until the 90th percentile flow where water overtopped the ridges. That woody vegetation mitigates erosion by decelerating water flow, thus maintaining rich morphology. Taken together, these findings suggest that as the more frequent erosive flow is contained within the swails, persistent woody vegetation is allowed the time to develop atop the ridges. In short, woody vegetation and patterns of hydrological flows play a role in preserving the ecosystem. All this considered how the interactions among river hydrology, geomorphology and vegetation contribute to unique patterns of scrollbar. Morphologies and woody vegetation on the Andersons is not fully understood. Future work will establish timescales associated with hydrological sediment, geological, geo, morphological and ecological processes within our study site and put them in context with other bands on the river. This knowledge is fundamental to determining how climate manifested through hydrological flow patterns and vegetation. Health influences the habitat viability within the lowland meandering system, thus is vital to successful management of river ecosystems and ecosystem services.
