Of, or referring to, a river, including the organisms within a river or the landforms produced by river action. Fluvial deposition dumps material worked or deposited by rivers; ‘at current sea levels, the locus of fluvial deposition is not necessarily the ocean, estuary, or delta, but floodplains in and upstream of the fluvial-estuarine transition zone’ (Phillips and Slattery (2006) PPG30, 4). Fluvial erosion is the destruction of bedrock on the sides and bottom of the river; the erosion of channel banks; and the breaking down of rock fragments into smaller fragments; see Powell et al. (2001) Water Resources Res. 37 and Wijdenes et al. (2001) ESPL26. Fluvial processes include erosion, flow processes, and sediment and solute transport in rivers; see Pitty, ed. (1979) Geoabstracts 127–47 and Reid et al. in A. Brown and T. Quine, eds (1999).
