Understanding the role of stream hydrologic and morphologic variables on the selection of spawning sites by salmonid fishes at high resolution across broad scales is needed for effective habitat restoration and protection. Here we used remotely sensed meter‐scale channel bathymetry for a 13.5 km reach of Chinook salmon spawning stream in central Idaho to describe habitat quality and set boundary conditions for a two‐dimensional surface water model coupled with a three‐dimensional hyporheic flux model. Metrics describing ambient hyporheic flow intensity and habitat quality, which is quantified as a function of stream hydraulics and morphology, were compared to the locations of nests built by female salmon. Nest locations were predicted most accurately by habitat quality followed by channel morphology (i.e., riffles location). As a lesser degree than habitat quality, water surface curvature was also a good indicator of spawning location because its intensity can identify riffle morphology. The ambient hyporheic flow predicted at meter‐scale resolution was not a strong predictor of redd site selection. Furthermore, the study suggests direct morphological measurements obtained from easily measured channel bathymetry data could enable effective and rapid assessments of salmon spawning channels across broad areas.

“…The APM solution was seminal to several studies that expanded the original solution to account for bedform geometry, bed thickness, heterogeneities of the porous medium, physicochemical properties of the transported substances, e.g., colloids and metals, surface chemographs, unsteady flow conditions, and groundwater discharge [ Packman et al ., , ; Packman and Brooks , ; Marion et al ., , , ; Zaramella et al ., , ; Cardenas et al ., ; Salehin et al ., ; Boano et al ., , ; Wörman et al ., , ; Cardenas and Wilson , , , ; Sawyer and Cardenas , ]. The effect of flow unsteadiness is particularly important as temporal variations of stream discharge are extremely frequent, and the consequent unsteady hyporheic exchange influences subsurface oxygen saturation [ O ' Connor et al ., ], temperature and reactive loads [ Marzadri et al ., , ], nitrogen transformation rates [ Wondzell and Swanson , ; Lautz and Fanelli , ], and mass exchange [ Malcolm et al ., ], thereby controlling the survival of salmonid embryos and the development of microbial biofilms [e.g., Duff and Triska , ; Greig et al ., ; Battin , ; Battin et al ., ; Wood et al ., , and references therein]. Temporal variations of streamflow properties influence the distribution of hydraulic head on the streambed surface.…”

Fifty years of hyporheic zone research have shown the important role played by the hyporheic zone as an interface between groundwater and surface waters. However, it is only in the last two decades that what began as an empirical science has become a mechanistic science devoted to modeling studies of the complex fluid dynamical and biogeochemical mechanisms occurring in the hyporheic zone. These efforts have led to the picture of surface-subsurface water interactions as regulators of the form and function of fluvial ecosystems. Rather than being isolated systems, surface water bodies continuously interact with the subsurface. Exploration of hyporheic zone processes has led to a new appreciation of their wide reaching consequences for water quality and stream ecology. Modern research aims toward a unified approach, in which processes occurring in the hyporheic zone are key elements for the appreciation, management, and restoration of the whole river environment. In this unifying context, this review summarizes results from modeling studies and field observations about flow and transport processes in the hyporheic zone and describes the theories proposed in hydrology and fluid dynamics developed to quantitatively model and predict the hyporheic transport of water, heat, and dissolved and suspended compounds from sediment grain scale up to the watershed scale. The implications of these processes for stream biogeochemistry and ecology are also discussed.

“…Sinusoidal oscillations have been observed to approximate the daily variations well for DO [10], temperature [11,12] and BOD [13]. Daily oscillations of DO are due to photosynthesis/respiration plant cycles, those of temperature to the day/night cycle, while BOD variations are chiefly correlated with discharge from wastewater treatment plants.…”

Hyporheic exchange carries reactive solutes, which may include biological oxygen demand (BOD), dissolved oxygen (DO) and reactive dissolved inorganic nitrogen (Nr), into the sediment, where biochemical reactions consume DO. Here, we study the impact of streambed morphology, stream-reactive solute loads and their diel oscillations on the DO benthic uptake rate (BUR) due to hyporheic processes. Our model solves the hyporheic flow field and the solute transport equations analytically, within a Lagrangian framework, considering advection, longitudinal diffusion and reactions modeled as first order kinetics. The application of the model to DO field measurements over a gravel bar-pool sequence shows a good match with measured DO concentrations with an overall agreement of 58% and a kappa index of 0.46. We apply the model to investigate the effects of daily constant and sinusoidally time varying stream BOD, DO and Nr loads and of the morphodynamic parameters on BUR. Our modeling results show that BUR varies as a function of bedform size and of nutrient loads and that the hyporheic zone may consume up to 0.06% of the stream DO at the pool-riffle bedform scale. Daily oscillations of stream BOD and DO loads have small effects on BUR, but may have an important influence on local hyporheic processes and organisms' distribution. OPEN ACCESSWater 2015, 7 399
