Sediment loads and accumulation in a small riparian wetland system in northern Missouri

Sediment transport and deposition along a stream in an agricultural basin (65 km²) in northern Missouri, USA were quantified as part of a long-term study to evaluate effects of silvicultural practices on the hydrology, sediment, vegetation, and wildlife characteristics of remaining forested riparian systems. Median cumulative sediment deposition, measured using feldspar clay pads, increased from August 1995 to August 1998 at a rate of about 1 cm/yr. Median deposition amounts from single floods ranged from 0.03 cm to 0.64 cm. Floodplain and riparian maintenance flows corresponded to monitored floods with calculated recurrence intervals as low as
