Effect of Surface Water Stage Fluctuation on Mixing‐Dependent Hyporheic Denitrification in Riverbed Dunes

open access: yesWater Resources Research, 2019
The hyporheic zone, where surface water (SW) and groundwater (GW) interact in shallow sediments beneath rivers, is uniquely reactive and attenuates pollutants.

The hyporheic zone and its functions: revision and research status in Neotropical regions

open access: yesBrazilian Journal of Biology
The hyporheic zone (HZ), as the connecting ecotone between surface- and groundwater, is functionally part of both fluvial and groundwater ecosystems. Its hydrological, chemical, biological and metabolic features are specific of this zone, not belonging ...

Numerical analysis of the impacts of bedform on hyporheic exchange

open access: yesShui kexue jinzhan, 2012
The impacts of irregular bedform in cross section on hyporheic exchange are studied by means of numerical simulation computations.The computation of the hyporheic exchange rate is done using the modular finite-difference ground-water flow model(MODFLOW ...

Colloid transport and distribution in the hyporheic zone

open access: yesHydrological Processes, 2019
AbstractColloids moving from the stream into the hyporheic zone may have a negative impact on aquatic ecosystems as they are potential contaminants or carriers of contaminants. Moreover, retained colloids in the hyporheic zone could not only reduce the exchange flux between the stream and streambed but also change the conditions of the bed, affecting ...

Modeling the impacts of streambed sediment heterogeneity on hyporheic exchange

open access: yesShui kexue jinzhan, 2019
The hyporheic exchange plays a crucial role in maintaining fluvial ecological processes. In order to examine the influence of streambed heterogeneity on the hyporheic exchange,a surface water-groundwater coupling model is constructed for solving flow ...

Influence of point bar on solute transportation in hyporheic zone within riparian zone with stratified structure

open access: yesShui kexue jinzhan
This study investigated the effect of point bar on solute transport in the hyporheic zone within a riparian zone (HZRZ) which had a stratified structure. Using a two-way flow riparian zone model,ten experimental groups were analysed.

The fate of polar trace organic compounds in the hyporheic zone

open access: yesWater Research, 2018
The hyporheic zone (HZ) is often considered to efficiently remove polar trace organic compounds (TrOCs) from lotic systems, mitigating potential adverse effects of TrOCs on ecosystem functioning and drinking water production. Predicting the fate of TrOCs in the hyporheic zone (HZ) is difficult as the in-situ removal rate constants are not known and the
