The AA. monitored fine sediment mobilization on a slope segment hydrologically connected to a stream in the ice-free Hoophorn Valley, New Zealand. Gerlach traps were installed in ephemeral slope channels to trap surficial material mobilized during rainfall events. Analyses of sediment-discharge hysteresis patterns were used to show if fine sediment connectivity was occuring between the monitored slope segment and the stream channel , and to permit identification of sediment sources within the catchment as a whole. Although the data set covers a relatively short-time period, this systematic approach enabled overall assessment of current controls on slope-to-channel fine sediment connectivity, and its implications for how the sediment transfer system in a formerly glacierized landscape may change over time
