Hyporheic hydraulic geometry: Conceptualizing relationships among hyporheic exchange, storage, and water age. [PDF]
PLoS ONE, 2022 Hyporheic exchange is now widely acknowledged as a key driver of ecosystem processes in many streams. Yet stream ecologists have been slow to adopt nuanced hydrologic frameworks developed and applied by engineers and hydrologists to describe the ...

How daily groundwater table drawdown affects the diel rhythm of hyporheic exchange [PDF]
Hydrology and Earth System Sciences, 2021 Groundwater table dynamics extensively modify the volume of the hyporheic zone and the rate of hyporheic exchange processes. Understanding the effects of daily groundwater table fluctuations on the tightly coupled flow and heat transport within hyporheic

Research progress of the unsteady hyporheic flow exchange process
Shuiwen dizhi gongcheng dizhi, 2022 The study of hyporheic exchange involves the physical mechanism, influencing factors and biochemical effects on the interaction of a surface water-groundwater system, which is a hot research topic in recent years in the disciplines of hydrology, ecology ...

Study of heterogeneous vertical hyporheic flux via streambed temperature at different depths [PDF]
Proceedings of the International Association of Hydrological Sciences, 2015 The hyporheic flux can be characterized using the heat-tracing method. Based on the analytical solution of the one-dimensional steady-state heat transport equation under vertical groundwater discharge conditions, hyporheic flux was obtained via a curve ...

Water Resources Research, 2023 Dissolved oxygen (DO) is critical for aquatic ecosystems, however, few studies have focused on the long‐term DO dynamics in hyporheic zones, which are a function of both transport (hydrologic exchange between river and hyporheic zone) and uptake by ...

Advance in field monitoring research of hydrodynamic process of hyporheic exchange in rivers
Shui kexue jinzhan, 2021 The hyporheic zone is the key transition region between rivers and aquifers, which is highly dynamic and sensitive. Frequent water exchange can trigger the bio-geochemical reactions within the hyporheic zone easily, and consequently make a difference to ...

Hyporheic exchange due to in-stream geomorphic structures
Journal of Freshwater Ecology, 2022 In-stream structures, such as channel spanning logs and weirs, can enhance hyporheic exchange in streams. Hyporheic exchange is important for stream ecosystem function, and restoring this function is a goal of many stream restoration projects.

Deposition process and mechanism of colloidal particles in hyporheic zone
Shui kexue jinzhan, 2021 The hyporheic zone is a region where surface and subsurface water mix in rivers. It is an important area for the exchange of mass and energy and an essential habitat for aquatic organisms.
