- •
Sediment source contribution was investigated in two paired agricultural catchments.
- •
Highest contribution to soil erosion were attributed to streambank and unpaved road.
- •
Streambanks contribution was higher during the rising limb of storm-events.
- •
Junctions between roads and the stream network increases unpaved road contribution.
- •
Cropland contribution was low due to sediment trapping promoted by wetlands.
