“…These layers show a characteristic succession of sedimentary features such as variable laminae thickness, organic carbon content or grain size distribution. The varved sediments can be dated by counting, thus sediment yield from the catchment can be deduced with a potentially high or even annual resolution ( [Zolitschka, 1998] and [Slaymaker et al, 2003]). There are problems and frequently the chronology has to be left floating within a time-frame established by another method such as 14 C. However, long chronologies such as that of Lake Suigetsu are now, as previously described, being used to provide improved radiocarbon chronologies ( [Kitagawa and von der Plicht, 1998] and [Kitagawa and von der Plicht, 2000]).…”

This paper reviews the traditional approach to sediment budget studies in geomorphology, new approaches and more specifically the potential impact of new methodological advances. Each component of the budget is discussed including the spatial and volumetric estimations of erosion, deposition and storage and the precision and accuracy of flux rate estimation. Examples are used from recent work in Germany, The Netherlands and the UK and include the pedogenic approach to erosion estimation, remote sensing (LiDAR), geophysics and sediment-based dating techniques for flux rate estimation. The precision and accuracy of catchment sediment flux estimates based upon sediment storage is not only dependant upon volumetric accuracy but also on the precision and accuracy of sediment dating. In this area there has been a revolution with direct sediment dating techniques (TL, OSL, ESR) freeing budget studies from the constraints and biases of radiocarbon. Of particular importance is the use of cosmogenic nuclides for dating but which can also be used to derive long-term erosion rates but only using a steady state assumption. Finally a tentative initial application of the sediment budget approach to Pleistocene terrace staircase in unglaciated basins is discussed. It is argued that only now do we have the techniques available to be able to produce accurate sediment budget estimations at spatial scales greater than that of zero order basins and over time periods greater than that covered by direct observations.

“…Few studies have attempted to reconstruct soil genesis using the geochemistry of lake or peat bog sediments (Mackereth, 1966;Engstrom and Hansen, 1985;Ford, 1990;Hu et al, 1993;Willis et al, 1997;Ewing and Nater, 2002;Slaymaker et al, 2003). Lacustrine sediment records yield a better temporal resolution of significant events in soil formation than the chronosequence approach based on substituting space for time (Ewing and Nater, 2002).…”

“…To help open the conceptual black box of erosional processes contributing sediment to a glacier we focus on periglacial processes within the context of a glacial sediment budget (Warburton, 1990;Harbor and Warburton, 1993;Slaymaker et al, 2003;Delmas et al, 2009). A simplifi ed conceptual schematic of the Matanuska Glacier basin's sediment budget over Holocene timescales identifi es the fl uxes we have attempted to quantify, as well as the fl uxes that we have not quantifi ed (Figure 2).…”

Glacial erosion rates are estimated to be among the highest in the world. Few studies have attempted, however, to quantify the fl ux of sediment from the periglacial landscape to a glacier. Here, erosion rates from the nonglacial landscape above the Matanuska Glacier, Alaska are presented and compare with an 8-yr record of proglacial suspended sediment yield. Non-glacial lowering rates range from 1·8 ± 0·5 mm yr −1 to 8·5 ± 3·4 mm yr −1 from estimates of rock fall and debris-fl ow fan volumes. An average erosion rate of 0·08 ± 0·04 mm yr −1 from eight convex-up ridge crests was determined using in situ produced cosmogenic 10 Be. Extrapolating these rates, based on landscape morphometry, to the Matanuska basin (58% ice-cover), it was found that nonglacial processes account for an annual sediment fl ux of 2·3 ± 1·0 × 10 6 t. Suspended sediment data for 8 years and an assumed bedload to estimate the annual sediment yield at the Matanuska terminus to be 2·9 ± 1·0 × 10 6 t, corresponding to an erosion rate of 1·8 ± 0·6 mm yr −1 : nonglacial sources therefore account for 80 ± 45% of the proglacial yield. A similar set of analyses were used for a small tributary sub-basin (32% ice-cover) to determine an erosion rate of 12·1 ± 6·9 mm yr −1 , based on proglacial sediment yield, with the nonglacial sediment fl ux equal to 10 ± 7% of the proglacial yield. It is suggested that erosion rates by nonglacial processes are similar to inferred subglacial rates, such that the ice-free regions of a glaciated landscape contribute signifi cantly to the glacial sediment budget. The similar magnitude of nonglacial and glacial rates implies that partially glaciated landscapes will respond rapidly to changes in climate and base level through a rapid nonglacial response to glacially driven incision.
