Book Review: Handbook of beach and shoreface morphodynamics
Abstract
coordinated pattern as the system opens up later in the summer. In Chapter 16, Richards and others present an integrated overview of the Arolla glaciology project during the early 1990s. Here, the authors (representing eight institutions) combine discharge quantity and quality variations with dye tracer studies and computer-based models of surface energy-balance and meltwater flow routing to summarize variations in the meltwater supplied by the glacier. Significantly, this chapter contains the first published account of Nienow's ground-breaking repeat dye-tracer experiment indicating that the channelized basal drainage system grows upglacier through the summer melt season, and that that growth closely follows the retreat of the surface snow- pack. Readers interested in the full version of this research experiment will find it in Nienow et al. (1998). The modeling sections of Chapter 16 are presented by Arnold in more detail in the penultimate Chapter 17, where model output is compared with field data from Haut Glacier d'Arolla. Finally, Alley (Chapter 18) presents noteworthy output from a computer model of water-pressure and sliding-velocity variations as water is forced into and out from a major subglacial channel. This paper represents a feasible (and to some extent subsequently overlooked) attempt to integrate a
