Abstract

Periglacial examples from Lapland and proglacial examples from Switzerland are used to illustrate the implications of investigative, particularly sampling, design for the rates and processes of sediment transfer that may be identified. By degrading 1-hourly and 2-hourly data sets it is shown that the major loss of detail in the discharge record occurs/when sampling interval increases from 12-hourly to 24-hourly, but that peaks are preferentially missed so that seasonal totals are underestimated. Suspended sediment concentration data, which are dominated by shorter duration events, display more extreme versions of the same effects
