Arsenic (As), chromium (Cr), and vanadium (V) are naturally occurring, redox-active
elements that can become human health hazards when they are released from aquifer …

Quantifying the impact of hyporheic exchange is crucial for understanding the transport and
fate of microplastics in streams. In this study, we conducted several Computational Fluid …

As floodplains are inundated during floods in a compound channel, solutes in the surface
water column reach the hyporheic zone and react with solutes upwelled from the …

Existing models for estimating hyporheic solute mass flux often require numerous
parameters related to flow, bed, and channel characteristics, which are frequently …

Pore-resolved direct numerical simulations have been performed to investigate the turbulent
open-channel flow over a rough and permeable sediment bed, represented by a mono …

This dissertation presents new insights into the interactions between surface water and
groundwater and their impact on various environmental processes. The study covers …
