“…Temperature buffering observed in the hyporheos ( Fig 4 ) depends on the water exchanges between the stream and the aquifer through the streambed [ 31 – 37 ]. Streambed exchanges qualitatively differ between sites, with various buffering across them.…”

“…Streambed exchanges qualitatively differ between sites, with various buffering across them. These differences along the Soultzbach stream are probably due to contrasting hydrodynamic and thermal properties of the encountered substrates [ 37 ]. More advanced modeling with an appropriate model [ 16 , 38 ] (DOI: 10.5281/zenodo.4058821 ) needs to be carried out to decipher these complex thermal exchanges.…”

The thermal regime of streams is a relevant driver of their ecological functioning. As this regime is presently submitted to numerous alterations (among others, impoundments, and climate change), it seems important to study both their effects and potential recovery from the latter. Thus, we investigated the surface and hyporheic water temperature along a small headwater stream with contrasting environmental contexts: forest landscape, open grassland landscape without riparian vegetation, several artificial run-of-the-river impoundments and one discharge point of a by-pass impoundment. The main objectives were to study the influence of these contrasting contexts on surface and subsurface water temperature at a local scale. Contrasting contexts were supposed to create effects on both surface and hyporheic thermal regimes at a local scale. Differences of thermal regimes between surface and hyporheos were expected, as well as between geological contexts. Sensors located at multiple stations allowed monitoring of stream and hyporheos temperature along the stream, while comparison with adjacent reference stream allowed for surface water thermal regime benchmark. Impoundments and landscapes significantly influenced stream thermal regime at a local scale (impoundments created up to +3.7°C temperature increase in average). Their effect on hyporheos thermal regime was less marked than the ones generated by solar radiation or geological features. Hyporheos thermal regime varies from stream one by temperature dynamics delay (up to 18h) and decrease (up to -7°C between surface and hyporheos temperature in average). These coupled effects create a mosaic of thermal habitats, which could be used for river biodiversity preservation and restoration.

“…It is enabled by the relative stability of groundwater temperatures, whereas stream temperatures exhibit strong diurnal and annual cycles. The propagation of daily river temperature signals in the hyporheic is particularly sensitive to flow variations because thermal properties are much less variable than hydraulic properties: thermal conductivity ranges between 1.5 and 6 W m −1 • C −1 for unconsolidated water saturated porous materials while hydraulic conductivity can vary over 6 orders of magnitude (e.g., Lapham, 1989;Constantz et al, 2002;Rivière et al, 2020). Various analytical and numerical methods based on the heat transfer equation have emerged (e.g., Stallman, 1965;Hatch et al, 2006;Rau et al, 2014;Irvine et al, 2020).…”

“…Section 2 introduces an application of the Bayesian framework for estimating statistical distributions of HZ hydrogeological and thermal properties from LOMOS-mini measurements. In line with Rivière et al (2020), section 3 applies the framework on a synthetic case study, investigating parameter identifiability for various hydrological and thermal forcings (exfiltration/infiltration, advective/conductive), as well as for a range of lithofacies. Section 4 applies the framework to in situ measurements collected in the Avenelles basin, France.…”

Located in the critical zone at the intersection between surface water and groundwater, hyporheic zones (HZ) host a variety of hydrological, biological and biogeochemical processes regulating water availability and quality and sustaining riverine ecosystems. However, difficulty in quantifying water fluxes along this interface has limited our understanding of these processes, in particular under dynamic flow conditions where rapid variations can impact large-scale HZ biogeochemical function. In this study, we introduce an innovative measurement assimilation chain for determining uncertainty-quantified hydraulic and thermal HZ properties, as well as associated uncertainty-quantified high-frequency water fluxes. The chain consists in the assimilation of data collected with the LOMOS-mini geophysical device with a process-based, Bayesian approach. The application of this approach on a synthetic case study shows that hydraulic and thermal HZ properties can be estimated from LOMOS-mini measurements, their identifiability depending on the Peclet number – summarizing the hydrological and thermal regime. Hydraulic conductivity values can be estimated with precision when greater than ~10−5m · s−1 when other HZ properties are unknown, with decreasing uncertainty when other HZ properties are known prior to starting the LOMOS-mini measurement assimilation procedure. Water fluxes can be estimated in all regimes with varying accuracy, highest accuracy is reached for fluxes greater than ~10−6m · s−1, except under highly conductive exfiltration regimes. We apply the methodology on in situ datasets by deriving uncertainty-quantified HZ properties and water fluxes for 2 data points collected during field campaigns. This study demonstrates that the LOMOS-mini monitoring technology can be used as complete and stand-alone sampling solution for quantifying water and heat exchanges under dynamic exchange conditions (time resolution < 15 min).
