Grain size distribution of suspended sediment during rainfall and snowmelt floods in small lowland river

This paper present information on particle size variation during rainfall and snowmelt flood from the small agricultural catchment. The grain size distribution during two rainfall, three snowmelt and one rainfall-snowmelt flood was compared. The average percentage of clays size material (<4 µm) for all samples was 2.7%, silt size material (> 4 µm and <62 µm) was 42.8% and sand (>62 µm) was 54.5%. The average median (d50) for floods ranged between 49.8 microns and 98.3 microns depend on the flood.
