The veligers were allowed to settle in the Imhoff cone for a minimum of 24 h.
Imhoff Cone determination of sediment in irrigated runoff.
Sediment loss from each furrow was measured frequently throughout the irrigation event using Imhoff cones.
The water in the Imhoff cone was poured into a 1-L beaker and the water was siphoned gently through a flat funnel measuring 5 cm in diameter with a mesh of 50-[micro]m.
The present work shows that by using the Imhoff cones, it is possible to carry out protein and carbohydrate analyses with the appropriate number of replicas without having to false huge amounts of larvae.
The software requires a calibration function, which converts settled sediment volume observed in one-liter Imhoff cone samples to weight of sediment per liter of runoff (12).
FRWSED can compute separate Imhoff cone calibration equations for different furrow groups, or treatments, and use them to compute erosion losses.
The spreadsheet, unlike FRWSED, does not calculate Imhoff cone calibrations.
78-L (1-gal) bucket, a one-liter Imhoff cone, and a flume.
Outflow" fields describe runoff monitoring/sampling times, runoff rate at the time monitored, and the Imhoff cone sediment volume for each runoff sample collected.
Inputs include sampling/monitoring time, outflow depth and flow rate and Imhoff cone settling volume.
