TL;DR: In this paper, the authors define biogeochemical hot spots as patches that show disproportionately high reaction rates relative to the surrounding matrix, whereas hot moments occur when episodic hydrological flowpaths reactivate and/or mobilize accumulated reactants.

TL;DR: A numerical hydrological simulation suggested that water exchange between stream channels and adjacent aquifers is enhanced by convexities and concavities in streambed topography.

TL;DR: In this paper, a review summarizes results from modeling studies and field observations about flow and transport processes in the hyporheic zone and describes the theories proposed in hydrology and fluid dynamics developed to quantitatively model and predict the hypheic transport of water, heat, and dissolved and suspended compounds from sediment grain scale up to watershed scale.

TL;DR: In this article, the authors evaluated the reliability of the stream tracer approach to characterize hyporheic exchange in St. Kevin Gulch, a Rocky Mountain stream in Colorado contaminated by acid mine drainage.
