Across Scales: An Examination of the Impacts of Turbulence and Mobile Bedforms on Hyporheic Exchange

Description:

In this dissertation, advances are made in understanding both the way hyporheic exchange impacts riverbed morphodynamics and the physical processes that lead to turbulent momentum transfer in the first few grains of riverbed sediments. In terms of physical advances in understanding the interplay between bedform movement and hyporheic exchange, we...

Modeling of Elastic Wave Propagation and Viscoelastic Characterization of Biofilms and Soft Materials

Description:

The viscoelastic properties of microbial biofilms have attracted great interests in recent years due to the ubiquity of biofilms and their wide range of industrial and municipal applications causing tremendous societal impacts. Biofilms are predominantly architected by extracellular polymeric substances (EPS) matrices composed of bacterial cells and biopolymers secreted by...
