“…HW, high waters, LW, low waters, DRW, dam release waters the dam. Such a process can result in DO depletion and anaerobic hyporheic conditions (Mestrov and Lattinger-Penko, 1981;Sprent, 1987). Contrary to station C, station A may be less influenced by water releases because it was richer in sand and more oxygenated because of SW richer in DO.…”

Nitrogen retention was measured along the Tafna wadi downstream of a heavily polluted reservoir in North-West Algeria to understand the role of the hyporheic zone (HZ) in nitrogen dynamics. Nutrient concentrations were measured monthly for 2 years within the bed sediments of a 300 m reach located 20 km downstream from the dam. Due to strong hydrological fluctuations hyporheic water was analysed during natural low and high water (HW) periods, and during water reservoir releases. Nutrient concentrations in surface water (SW) increased during water releases and in the HZ during the low water (LW) periods. Surface/hyporheic water interactions were characterized by determining the vertical hydraulic gradient (VHG) and the chemical signature of the ground water (GW). The latter was obtained from regional GW monitoring. Hyporheic chemistry was strongly influenced by patterns of surface flow. Hyporheic and SWs had similar chloride concentrations during high flow when they were significantly lower than those of the regional GW. GW was generally richer in nitrates and nitrites, but was lower in ammonium concentrations than interstitial and river waters. Nitrates decreased significantly from upstream to downstream within the HZ throughout the hydrological period even though temporal fluctuations were high. Ammonium concentrations in interstitial water (IW) were significantly higher than in SW and generally increased from upstream to downstream. This study demonstrates the importance of the HZ in altering the dissolved inorganic nitrogen composition and concentrations of heavily polluted arid streams. The study is of interest because it documents a large 'natural experiment' that being the effect of periodic water release from a reservoir with serious water quality problems on the water quality dynamics (particularly nitrogen) of subsurface and SWs downstream.

“…The saturated interstitial space below the river bed and within the banks that holds a proportion of surface water is referred to as the hyporheic zone (White, 1993). It has great ecological significance as a hatchery for salmonid and invertebrate eggs (Hynes, 1983;Shepherd, 1984), as a refuge for invertebrates and larval fish during spates (Hynes et al, 1976;Poole & Stewart, 1976), low flows and pollution events (Williams, 1977;Mestrov & Lattinger-Penko, 1981); and constitutes a prominent area of stream metabolism (Grimm & Fisher, 1984;Valett et al, 1990). Temperature is a fundamental biological variable (Hynes, 1970).…”

This paper outlines the results of a pilot study using data at 12 min intervals from 20 miniature temperature dataloggers to establish vertical and longitudinal temperature patterns within a river bed. Data are presented from two adjacent riffles immediately below the Blithfield Reservoir on the River Blithe, Staffordshire, UK, for a five day period in July 1994. Hyporheic temperatures were warmer than those of groundwater, colder than those of surface water and decreased with depth into the river bed. At the heads of the riffles shallow sites (20 cm depth) mirrored surface temperature patterns but were on average 1.53°C cooler while deeper sites (40 cm depth) were 2.60°C cooler on average. Hyporheic temperatures lagged behind the surface water pattern and lag times increased with depth. Sites at the riffle tails generally displayed temperature patterns similar to those of the groundwater system: on average, temperatures were 4.32°C cooler than surface water temperatures and showed no significant variation. Hyporheic temperature patterns at the heads of the riffles suggested downwelling surface water, while the tails appeared to be influenced by upwelling groundwater. Both riffles displayed similar hyporheic temperature patterns but riffle 1 was on average 1.22°C warmer per site than riffle 2. Temperature differences between the riffles are attributed to bed form and substratum composition. These factors may have significant ecological implications including rates of organic matter decomposition, invertebrate life cycles and salmonid egg hatching times.

“…Invertebrate assemblages varied with depth in both channels: SB were most abundant in deep zones (D3), and the benthic taxa (SX, TH) were mostly distributed in the top layer (D1, Figure a,b, Figure a,b). Variation with depth is a very common and dominant feature of the distribution and composition of the hyporheos (e.g., Danielopol, ; Dole & Chessel, ; Dole‐Olivier, Marmonier, & Creuzé des Châtelliers, ; Gibbins, Grant, Malcolm, & Soulsby, ; Mestrov & Lattinger‐Penko, ; Williams, ). In the present study, this effect was particularly strong.…”

Do benthic invertebrates use hyporheic refuges during streambed drying? A manipulative field experiment in nested hyporheic flowpaths

et al. 2017

The existence of resilience mechanisms related to a disturbance, such as invertebrate migrations into the hyporheic zone (HZ, saturated subsurface interstices), promotes persistence of benthic communities in river ecosystems. Water exchanges through the HZ, which influence the distribution of biota, are heterogeneous at different scales, determining nested hyporheic flowpaths. The effect of these nested exchanges on the use of the hyporheic refuges by benthic invertebrates is still unknown. We simulated streambed drying in a stream section where hydrological exchanges were considered at riffle (upstream or downstream of riffles) and floodplain (downstream end of a floodplain) scales. Physicochemical indicators determined that local hyporheic flowpaths (up-and downwelling zones) were nested in a large-scale downwelling section of the river. In this situation, the effect of 24 h of experimental drying on the distribution of invertebrates was examined at three sediment depths to follow their migrations into the HZ. Whereas invertebrate assemblages did not change in the control channel, abundance of benthic invertebrate increased in the HZ of the impact channel (up to seven-fold). Changes occurred rapidly (15-24 h) and only upstream of riffle where surface water down-welled. The migration was taxon-specific and concerned the most abundant benthic taxa that temporarily colonize the HZ ("temporary hyporheos," e.g., Leuctra cf. fusca, Baetis sp., Caenis sp., Orthocladiinae, Tanypodinae). In the context of climate change, hyporheic refuge use will promote persistence of communities facing the increasing frequency of extreme hydrological events. Improved knowledge about the distribution and function of these refuges is becoming crucial for river managers. to induce physical and hydrological modifications in rivers and streams (Rolls, Leigh, & Sheldon, 2012). Flow regimes are especially affected with more extended low flows and higher frequencies of extreme events, such as floods and droughts (Dai, 2011;Lehner, Döll, Alcamo, Henrichs, & Kaspar, 2006). During severe events, threats to the aquatic environment are likely to increase, with resistance and resilience becoming crucial properties of communities. Resilience, that is, the return time to a stable state following a perturbation (Gunderson, 2000), may be enhanced by the use of in-stream refuges by benthic invertebrates (Lake, 2003). Refuges are places where the negative effects of disturbance are weaker than in the surrounding area (Lancaster & Belyea, 1997). Refuges that facilitate post-drying resilience include the use of microhabitats available in the streambed (Stubbington, 2012) or within the alluvia. In permeable streambeds, the hyporheic zone (HZ) may offer preferable living conditions for invertebrates during hydrological disturbance (Angelier, 1953;Dole-Olivier & Marmonier, 1992a;Marmonier & Dole, 1986). The hyporheic refuge hypothesis (HRH, Palmer, Bely, & Berg, 1992) proposes that benthic invertebrates increase their survival of adverse condition...
