The Fluid & Sediment Dynamics research group conducts studies in the area of environmental hydraulics and sediment transport. It is led by Dr. Kyle Strom and is part of the Department of Civil and Environmental Engineering at Virginia Tech.
We study the movement of water, sediment, and other substances in a range of aquatic environments (e.g., rivers, lakes, estuaries, and the ocean). A broad topic of interest for us within this theme is how the interaction between the flow and sediment forms and sculpts our waterways and landscapes. We study such processes at small spatial and temporal scales where turbulent motion and the interaction of individual sediment particles in the bed or water column influence the dynamics at play. We also study these processes at larger scales where drivers such as climate, manmade alterations to rivers, or the installation of infrastructure influence rivers and deltas over time scales of years to centuries. In all of our work, we are interested in understanding basic processes, developing new experimental methods, and creating quantitative tools for forward and backward modeling. Improving our understanding and ability to model natural systems aids responsible management of river and coastal resources, and helps to give a more accurate understanding of earth’s history and its future trajectory.
We are excited to be a part of the research team studying controls on the physical conditions within mounded nests built by the Bluehead Chub. The effort is led by Emmanuel Frimpong from the Virginia Tech College of Natural Resources…
How is silt size in a deposit related to current velocity and other flow and sediment characteristics?
This is a question we tackled experimentally with Brian Romans and Andrew Parent for systems dominated by advective dispersal of sediment. Results of the study are presented in Culp et al. (2021). The figure below summarizes some of the main…
This is a question Duc Tran tackled in a recent paper (Tran and Strom 2019). Overview: Cohesive mud flocs in coastal waterways can go through repeated cycles of deposition and erosion before being sequestered in a final deposit. Unlike sand…
