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.
