Sediment transport output is classified into two groups referred to as Output Blocks: (1) Sediment Transport and (2) Sediment Bed. The main reason for this classification is to be able to easily control the output interval of variables which vary at similar time scales. Generally, "transport variables" which are usually within the water column (e.g. concentrations, transport rates, etc.) vary at time scales similar to the hydraulics, while sediment variables on the bed (e.g. bed elevations and gradations) vary at longer time scales. Allowing the user to specify different output intervals for these two output groups helps reduce the size of the HDF5 Output File by allowing the user to specify a larger output interval for variables which change slowly, compared to the hydraulics. The variables which correspond to the Sediment Bed are the bed roughness's, bed elevations, bed changes, bed change rate, bed slopes, bed layer fractions, bed layer thicknesses, bed layer percentile diameters, bed layer dry densities. All other variables correspond to the Sediment Transport group. The precise Output Block for each output variable is noted in the captions of Tables 26 through 214.
