On The Inference Of The State Of Turbulence And Mixing Efficiency In Stably Stratified Flows, Amrapalli Garanaik, Subhas K. Venayagamoorthy

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Scaling arguments are presented to quantify the widely used diapycnal (irreversible) mixing coefficient Γ = ∈PE/∈ in stratified flows as a function of the turbulent Froude number Fr = ∈/Nk. Here, N is the buoyancy frequency, k is the turbulent kinetic energy, ∈ is the rate of dissipation of turbulent kinetic energy and ∈PE is the rate of dissipation of turbulent potential energy. We show that for Fr≫1, Γ ∝ Fr^-2, for Fr∼ O (1), Γ ∝ Fr^-1 and for Fr ≪ 1, Γ ∝ Fr⁰. These scaling results are tested using high-resolution direct numerical …

Detection Of Sand Boils From Images Using Machine Learning Approaches, Aditi S. Kuchi

LSU New Orleans Theses and Dissertations

Levees provide protection for vast amounts of commercial and residential properties. However, these structures degrade over time, due to the impact of severe weather, sand boils, subsidence of land, seepage, etc. In this research, we focus on detecting sand boils. Sand boils occur when water under pressure wells up to the surface through a bed of sand. These make levees especially vulnerable. Object detection is a good approach to confirm the presence of sand boils from satellite or drone imagery, which can be utilized to assist in the automated levee monitoring methodology. Since sand boils have distinct features, applying object …
