Identifying the dominant physical processes for mixing in full-scale raceway tanks
… It is proposed that the promotion of cellular, secondary currents by introduction of longitudinal ridges along the bed of the reactor can both promote vertical mixing and enhance gas transfer across the free surface of the growth medium. Experiments are performed in a full-scale open RWT at the …

Channel Processes and form Near the Tidal Limit
… influence along a river channel, freshwater currents transition from fully unidirectional to fully bi-directional. The goal of this study is to investigate channel conditions near the upstream tidal limit of the Santee River, SC. I measured velocity profiles, bathymetry, channel geometry, and …

Mineralogy, Chemistry & Flux of Suspended Sediments in Himalayan Rivers
… with depth, likely from the the highly turbulent secondary currents. Sediments have statistically higher Na/Al ratios and marginally lower K/Al ratios downstream at the Himalayan Front compared to those in the Himalayan Range. This downstream variation occurs from a greater abundance of …
