How does daily groundwater table drawdown affect the diel rhythm of hyporheic exchange?
. 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 ...

Bedform characteristics and biofilm community development interact to modify hyporheic exchange [PDF]
The physical and biological attributes of riverine ecosystems interact in a complex manner which can affect the hydrodynamic behaviour of the system. This can alter the mixing characteristics of a river at the sediment-water interface.

Engineered Gravel Trench Hyporheic Exchange to Create Cold‐Water Thermal Refuges
ABSTRACT Warming rivers are driving a loss or fragmentation of cold‐water habitat and providing the impetus to develop proactive thermal management approaches to maintain suitable habitat in rivers. One innovative approach is through the creation of cold‐water thermal refuges during periods of thermal stress for aquatic species.

ABSTRACT Low‐tech process‐based stream restoration (LTPBR) is increasingly implemented following wildfire, underscoring the need to evaluate restoration outcomes in burned catchments. To help address this need, we measured abiotic and biotic characteristics of a reach that received LTPBR, an untreated reach, and a reach with relict beaver activity that

In-stream and hyporheic water quality of the River Esk, North Yorkshire: implications for Freshwater Pearl Mussel habitats [PDF]
River systems and their catchments are important for ecological, social and economic reasons. However, the increased and changing usage of these natural environments and resources for anthropogenic benefit have led to degradation in water quality, which ...

Hyporheic exchange controlled by dynamic hydrologic boundary conditions [PDF]
AbstractThe relative roles of dynamic hydrologic forcing and geomorphology as controls on the timescales and magnitudes of stream‐aquifer exchange and hyporheic flow paths are unknown but required for management of stream corridors. We developed a comprehensive framework relating diel hydrologic fluctuations to hyporheic exchange in the absence of ...

Abstract Global warming is causing rapid and profound impacts on northern ecosystems. Shifting precipitation, permafrost thaw, and rapid shrub advance into tundra environments are combining to alter stream temperature in uncertain ways. The expansion and increased abundance of shrub vegetation, termed shrubification, may moderate warming stream ...

Integrating Flow and Solute Flux Dynamics in an Adaptive LSTM Model for Stream Chemistry Predictions
Abstract High‐frequency measurements of stream solute dynamics reveal fluctuations across a multitude of time‐scales. At the storm‐event time‐scales they expose solute specific rapid mobilization or dilution effects, in addition to hysteresis. For various applications, predictions of these dynamics at measurement sites are desired to inform impending ...

Abstract Self‐potential (SP) monitoring has emerged as a valuable method for characterizing subsurface hydrogeological features and processes due to its sensitivity to fluid‐induced electrokinetic effects. Despite advancements in SP inversion, challenges remain in imaging groundwater dynamics from SP activities due to complex hydrological settings and ...

Effects of Successive Peak Flow Events on Hyporheic Exchange and Residence Times [PDF]
Hyporheic exchange is a crucial control of the type and rates of streambed biogeochemical processes, including metabolism, respiration, nutrient turnover, and the transformation of pollutants.
