“…Since rivers have fractal topography and interactions between river flow and boundary topography drive hyporheic exchange [Harvey and Bencala, 1993;Stonedahl et al, 2010;Tonina and Buffington, 2011;Kiel and Cardenas, 2014;Gomez-Velez and Harvey, 2014], the ubiquitous fractal properties of rivers should produce fractal patterns in hyporheic flow paths and fractal scaling in the associated residence time distributions [Worman et al, 2007;Stonedahl et al, 2012]. Other mechanisms that can produce broad travel time distributions include subsurface heterogeneity and nested flow paths in homogeneous systems [Kirchner et al, 2001;Scher et al, 2002;Cardenas, 2007].…”

River topography is famously fractal, and the fractality of the sediment bed surface can produce scaling in solute residence time distributions. Empirical evidence showing the relationship between fractal bed topography and scaling of hyporheic travel times is still lacking. We performed experiments to make high‐resolution observations of streambed topography and solute transport over naturally formed sand bedforms in a large laboratory flume. We analyzed the results using both numerical and theoretical models. We found that fractal properties of the bed topography do indeed affect solute residence time distributions. Overall, our experimental, numerical, and theoretical results provide evidence for a coupling between the sand‐bed topography and the anomalous transport scaling in rivers. Larger bedforms induced greater hyporheic exchange and faster pore water turnover relative to smaller bedforms, suggesting that the structure of legacy morphology may be more important to solute and contaminant transport in streams and rivers than previously recognized.

“…In sinuous rivers it forms along river banks (Cardenas 2009), and in the wide alluvial valleys of a long meandering river, almost all of the river water can circulate through the lateral part of this zone (Kiel & Cardenas 2014). In the low gradient reach of a sandy alluvial river the hyporheic flow can extend over hundreds of meters across the valley.…”

Abstract:The concentrations of zinc and cadmium were determined in the sediment cores sampled from the floodplain and the channel in the middle reach of the Biała Przemsza River valley (southern Poland). The results were compared to the river water and groundwater chemistry in order to reveal the average extent of the hyporheic flow. The loss of river waters through the river bed due to the natural migration modified by the drainage of the lead-zinc ore mine caused the strong pollution of the river bed sediments with heavy metals to the depth of almost three meters below the water table in the river. Moreover, the similar groundwater and river water chemistry at that depth suggests that the vertical extent of the hyporheic zone, which exceeds a depth of several meters below the channel, can be affected by the drainage of river waters by the lead-zinc mine. The lateral extent of the hyporheic flow, indicated by changes in groundwater chemistry and elevated heavy metal concentrations in the sediments, was of the order of dozen of meters. The investigation documents the large impact of the secondary in situ enrichment of sediments with heavy metals in the hyporheic zone.

“…While two recent studies have observed vertical and lateral exchange throughout the Mississippi River watershed (Kiel et al, 2014;Gomez et al, 2014), lateral exchange has been explored mostly by modelling studies, and much less field data are available on lateral hyporheic exchange than on vertical exchange. Most studies have focused on a single factor or a subset of factors, despite the fact that lateral hyporheic flows are known to be modulated by processes at at least two scales: channel planform (valley scale) and bedform morphology (channel scale) (Stonedahl et al, 2013).…”

“…Sinuosity is often used as a measure of channel complexity and has been seen to be directly correlated to lateral hyporheic exchange in meander bends, and in parafluvial zone beneath the streambanks (Holmes et al, 1996;Wroblicky et al, 1998;Boano et al, 2006;Cardenas, 2008a;Kiel and Cardenas, 2014). Sinuosity influences the amount 25 of water exchanged within a river segment (Brunke and Gonser, 1997) because changes in streambed plan form can alter the path of subsurface intra-meander ecosystem, including the HEF (Boano et al, 2006Cardenas, 2009a;Gomez et al, 2012;Han and Endreny, 2013).…”

Abstract. Rivers are not isolated systems but continuously interact with the subsurface from upstream to downstream. In the last few decades, research on the hyporheic zone (HZ) from many perspectives has increased appreciation of the hydrological importance and ecological significance of connected river and groundwater systems. Although recent reviews, 10 modelling and field studies have explored hydrological, biogeochemical and ecohydrological processes in the HZ at relatively small scales (bedforms to reaches), a comprehensive understanding of the factors driving the hyporheic exchange flows (HEF) at larger scales is still missing. To date, there is fragmentary information on how hydroclimatic, hydrogeologic, topographic, anthropogenic and ecological factors interact to drive hyporheic exchange flows at large scales. Further evidence is needed to link hyporheic exchange flows across scales. This review aims to conceptualize interacting factors at catchment, 15 valley and reach scales that control spatial and temporal variations in hyporheic exchange flows. The implications of these drivers are discussed for each scale, and co-occurrences across scale are highlighted in a case of study. By using a multi-scale perspective, this review connects field observations and modelling studies to identify broad and general patterns of HEF in different catchments. This multi-scale perspective is useful to devise approaches to interpret hyporheic exchange across multiscale heterogeneities, to infer scaling relationships, and to inform watershed management decisions. 20
