“…At the larger (up to several kilometre) stream reach to sub-catchment scale, exchange fluxes between groundwater and surface water can be strongly affected by larger geological heterogeneities in the alluvial aquifer and the resulting groundwater flow field (Cardenas and Wilson, 2006;Fleckenstein et al, 2006;Engdahl et al, 2010;Frei et al, 2009). At smaller, plot to stream reach scales, however, exchange fluxes over the aquifer-river interface appear to be strongly controlled by spatial patterns of streambed hydraulic conductivity (Genereux et al, 2008;Leek et al, 2009;Calver, 2001;Rosenberry, 2008;Käser et al, 2009) and streambed topography (Storey et al, 2003;Boano et al, 2006Boano et al, , 2010Cardenas, 2009;Cardenas et al, 2008;Kasahara and Hill, 2008;Tonina and Buffington, 2007).…”

Abstract. This paper investigates the patterns and controls of aquifer-river exchange in a fast-flowing lowland river by the conjunctive use of streambed temperature anomalies identified with Fibre-optic Distributed Temperature Sensing (FO-DTS) and observations of vertical hydraulic gradients (VHG).FO-DTS temperature traces along this lowland river reach reveal discrete patterns with "cold spots" indicating groundwater up-welling. In contrast to previous studies using FO-DTS for investigation of groundwater-surface water exchange, the fibre-optic cable in this study was buried in the streambed sediments, ensuring clear signals despite fast flow and high discharges. During the observed summer baseflow period, streambed temperatures in groundwater up-welling locations were found to be up to 1.5 • C lower than ambient streambed temperatures. Due to the high river flows, the cold spots were sharp and distinctly localized without measurable impact on down-stream surface water temperature.VHG patterns along the stream reach were highly variable in space, revealing strong differences even at small scales. VHG patterns alone are indicators of both, structural heterogeneity of the stream bed as well as of the spatial heterogeneity of the groundwater-surface water exchange fluxes and are thus not conclusive in their interpretation. However, in combination with the high spatial resolution FO-DTS data we were able to separate these two influences and clearly identify locations of enhanced exchange, while also obtaining information on the complex small-scale streambed transmissivity patterns responsible for the very discrete exchange patterns. The validation of the combined VHG and FO-DTS approach provides an effective strategy for analysing drivers and controls of groundwater-surface water exchange, with implications for the quantification of biogeochemical cycling and contaminant transport at aquifer-river interfaces.

“…This pattern of fine sediment deposition (typically sand-and silt-sized fractions of B2 mm; Wentworth, 1922;Jones et al, 2012) directly influences the structure and composition of invertebrate communities (Brunke & Gonser, 1999) but also the nature of vertical hydrological exchange (Leek et al, 2009;Hartwig & Borchardt, 2015;Datry et al, 2015). Consequently, the dynamic pattern of vertical hydraulic exchange exerts a strong influence on physical and chemical conditions such as temperature, oxygen concentrations and the residence time of water (Olsen & Townsend, 2003;Krause et al, 2011b).…”

Benthic and hyporheic macroinvertebrate distribution within the heads and tails of riffles during baseflow conditions

The distribution of lotic fauna is widely acknowledged to be patchy reflecting the interaction between biotic and abiotic factors. In an in situ field study, the distribution of benthic and hyporheic invertebrates in the heads (downwelling) and tails (upwelling) of riffles were examined during stable baseflow conditions. Riffle heads were found to contain a greater proportion of interstitial fine sediment than riffle tails. Significant differences in the composition of benthic communities were associated with the amount of fine sediment. Riffle tail habitats supported a greater abundance and diversity of invertebrates sensitive to fine sediment such as EPT taxa. Shredder feeding taxa were more abundant in riffle heads suggesting greater availability of organic matter. In contrast, no significant differences in the hyporheic community were recorded between riffle heads and tails. We hypothesise that clogging of hyporheic interstices with fine sediments may have resulted in the homogenisation of the invertebrate community by limiting faunal movement into the hyporheic zone at both the riffle heads and tails. The results suggest that vertical hydrological exchange significantly influences the distribution of fine sediment and macroinvertebrate communities at the riffle scale.

“…It is important to note that the direction of the vertical flow of the river is not always the same, according to Leek et al (2009). They report that the hydraulic gradient can present spatial variation in its behavior at nearby locations.…”

The interaction between groundwater and surface water occurs naturally and is dependent on the dynamics in the hyporheic zone. The hyporheic zone is the interface between the surface water source and the phreatic aquifer and it's a system that also influences the water quality. An important feature is the ability to flux in this zone. This work aimed to evaluate the vertical hydraulic gradient in the hyporheic zone at two points in Beberibe river, Olinda-PE, to understand the hyporheic environment characteristics and water flow dynamics in experimental area, in addition to identify the existence of hydraulic connection between surface water and groundwater. The experimental phase consisted of infiltration tests in riverbed with cylinder infiltrometer and vertical hydraulic gradients readings with differential piezometer, complemented with grain size information, for an assessment of the water budget between the river and the aquifer. Analyzing the behavior of the interaction over the period of 10 months, it was observed that the Beberibe river (middle course) contributes to the groundwater recharge in most of the time. The average infiltration rate was 1.02 mm/min in point 1 and 0.85 mm/min in point 2. It was concluded that there is a variability in flow direction, which often is top-down, but may undergo change in the stream showing upstream after long periods of rainfall. Another conclusion is that grain size distribution of bed sediment, that is predominantly sandy, influences hydraulic conductivity of hyporheic zone and influences consequently the vertical flow rates.Keywords: River-aquifer interaction; Infiltration; Cylinder infiltrometer; Differential piezometer; Hyporheic zone. RESUMOA interação entre águas subterrânea e superficial ocorre naturalmente e depende da dinâmica na zona hiporreica. A zona hiporreica é a interface entre o corpo hídrico superficial e o meio subterrâneo, sendo um sistema que também influencia a qualidade da água. Uma importante característica é a capacidade de fluxo nesta zona. O trabalho objetivou avaliar o fluxo vertical de água na zona hiporreica em dois pontos do rio Beberibe, Olinda -PE, para compreender as características do ambiente hiporreico e a dinâmica do fluxo de água nesta zona, além de identificar a existência de conexão hidráulica entre a água superficial e subterrânea. A fase experimental consistiu em ensaios de infiltração no leito com infiltrômetro de cilindro e leituras da diferença da carga hidráulica com piezômetro diferencial, complementadas com informações granulométricas, para uma avaliação da capacidade de transporte de volumes hídricos entre o rio e o aquífero. Analisando-se o comportamento da interação ao longo do período de 10 meses, verificou-se que o rio Beberibe no seu curso médio contribui para a recarga do lençol freático em boa parte do tempo, sendo a média da taxa de infiltração de 1,02 mm/min no ponto 1 e de 0,85 mm/min no ponto 2. Concluiu-se que há uma variabilidade no sentido do fluxo, que geralmente é de cima para baixo, mas pode so...
