“…This ‘stepping’ has been observed in the adjacent River North Tyne by Sear (), in which individual higher magnitude flood events resulted in an order of magnitude increase in sediment accumulation compared to smaller flood events. The step‐like nature of the accumulation (Figure a) is in accordance with observations from continuous recording fine sediment traps (Fletcher and McLean, ).…”

Dissolved oxygen (DO) plays a critical role in the development of the juvenile stages of benthic spawning fish and salmonids in particular. Factors influencing the DO regime within spawning gravels include the accumulation of fine sediment, penetration of groundwater or surface water into the gravels, thermal regime, and the consumption of oxygen by sediment and its associated organic fractions. In this field study, we quantify the DO regime within an artificial salmon redd at high temporal resolution. The environment within the redd is shown to be complex, with large variations in DO. Application of a numerical model (SIDO‐UK) enables for the first time, the quantification of the relative contributions to DO consumption from thermal regime, sediment accumulation and sediment oxygen demand. Sediment accumulation is shown to have a minor impact on DO in the redd whereas upwelling groundwater is identified as the most likely cause of the major changes in DO. Bed mobility has a minor impact on DO regime of the redd. The effects of fine sediment and oxygen supply on salmon embryo survival are estimated. Implications for river catchment management and prospects for future research are discussed. Copyright © 2012 John Wiley & Sons, Ltd.

“…Although several methods have been used to monitor embryo survival (Harris, 1973;Gustafson-Marjanen and Moring, 1984;Lacroix, 1985;Mackenzie and Moring, 1988;Scrivener, 1988;Rubin, 1995;Donaghy and Verspoor, 1997) or fine sediment infiltration (Lisle, 1989;Wesche et al, 1989;Lisle and Eads, 1991;Lisle and Lewis, 1992;Fletcher et al, 1995;Clarke andScruton, 1997, Acornley andSear, 1999;Soulsby et al, 2001;Bond, 2002), none of them allows concurrent field measurements of embryo survival and fine sediment content in an environment reproducing a natural salmonid redd. A natural redd has a surface morphology and grain size composition which is distinct from the adjacent undisturbed gravel (Kondolf et al, 1993).…”

The infiltration cube method presented in this paper allows concurrent field measurement of fine sediment content and embryo survival in an incubating environment reproducing, as closely as possible, the morphology and grain size composition of a natural salmonid redd. An infiltration cube is made up of a rectangular (30 cm square and 20 cm high) steel frame with no walls, which has a folded plastic bag attached to its base. Each infiltration cube is buried in the substrate using a procedure aimed at reproducing, as closely as possible, the construction and morpho-sedimentological structure of a natural salmonid redd. Using a tripod installed on the river bed or at the surface of the ice, the infiltration cube method provides a quick, easy and robust way to pull relatively large samples (approximately 65 kg) out of underwater substrate even during tough winter field conditions. The absence of walls on the cube also precludes bias in infiltration rates by both allowing lateral sediment transport within substrate and preventing loss of fine particles during retrieval from underwater.
