A Tracer-Based Method for Classifying Groundwater Dependence in Boreal Headwater Streams
TLDR
In this paper, a classification method for the groundwater dependence of headwater streams was devised based on the fact that GW affects discharge, thermal regime, and water quality, which can serve as a water management tool, especially for streams of exceptional ecological importance or in places where anthropogenic activities are expected to change local hydrology and ecology.About:

Assessing the role of location and scale of Nature Based Solutions for the enhancement of low flows
TL;DR: In this article , Runoff Attenuation Features (RAFs) are used to intercept and attenuate flow pathways during wet periods, increasing infiltration opportunity and thus water availability for use later.

Abstract: Water flows in peatland margins is an under-researched topic. This study examines recharge from a peatland to an esker aquifer in an aapa mire complex of northern Finland. Our objective was to study how the aapa mire margin is hydrogeologically connected to the riverside aquifer and spatial and temporal variations in the recharge of peatland water to groundwater (GW). Following geophysical studies and monitoring of the saturated zone, a GWmodel (MODFLOW) was used in combination with stable isotopes to quantify GW flow volumes and directions. Peatland water recharge to the sandy aquifer indicated a strong connection at the peatland–aquifer boundary. Recharge volumes from peatland to esker were high and rather constant (873 m d ) and dominated esker recharge at the study site. The peat water recharging the esker boundary was rich in dissolved organic carbon (DOC). Stable isotope studies on water (δO, δH, and d-excess) from GW wells verified the recharge of DOC-rich water from peatlands to mineral soil esker. Biogeochemical analysis revealed changes from DOC to dissolved inorganic carbon in the flow pathway from peatland margin to the river Kitinen. This study highlights the importance of careful investigation of aapa mire margin areas and their potential role in regional GW recharge patterns.

Stream water age distributions controlled by storage dynamics and nonlinear hydrologic connectivity: Modeling with high-resolution isotope data.
TL;DR: A new long‐term record of daily isotope measurements in precipitation and streamflow was used to calibrate and test a parsimonious tracer‐aided runoff model, well suited for constraining process‐based modeling in a range of northern temperate and boreal environments.

The Role of Ground Water in Generating Streamflow in Headwater Areas and in Maintaining Base Flow
TL;DR: The volume and sustainability of streamflow from headwaters to downstream reaches commonly depend on contributions from ground water as mentioned in this paper, and nearly all streams need to have some contribution from groundwater in order to provide reliable habitat for aquatic organisms.
Climate Change Effects
TL;DR: A fact sheet that contains key scientific facts that support EPA's determination that greenhouse gases in the atmosphere endanger public health and the welfare of current and future generations is presented in this paper.

Accounting for groundwater in stream fish thermal habitat responses to climate change.
TL;DR: Air-water temperature regression models can provide a powerful and cost-effective approach for predicting future stream temperatures while accounting for effects of groundwater and Habitat fragmentation due to thermal barriers may have an increasingly important role for trout population viability in headwater streams.

Advancing tracer-aided rainfall–runoff modelling: a review of progress, problems and unrealised potential
TL;DR: Tracer data have been invaluable in providing rich insights into runoff sources, flow paths and water age that cannot be established by simple rainfall-runoff dynamics alone as mentioned in this paper, and this has provided a focus for fertile dialogue between field hydrologists and modellers in joint efforts to understand catchment function and incorporate this in runoff models.
