The Sediment Grading object is used when carrying out sediment modelling in River Reaches.

The sediment grading allows bed material distribution to be defined by specifying the proportion of each sediment fraction that is present.

The sediment grading is associated with a River Reach or Bridge by referencing the grading object using the river reach/bridge grading data fields.
