cumulative_sediment(d, time.col = "Time", grain.col = "GrainClass",
  over.time = TRUE, longitudinal = TRUE, direction = c("upstream",
  "downstream"))

`d`	A wide-format table containing values to accumulate.
`time.col`	The time column name.
`grain.col`	the grain class column name.
`over.time`	If `TRUE`, accumulate data across time steps. This is generally valid only for data output at the computation time step.
`longitudinal`	If `TRUE`, accumulate data along the reach. This is generally only valid when all cross sections are included in `d`.
`direction`	Accumulate data in the downstream (descending order of cross section IDs) or upstream (ascending order) direction. Ignored if `longitudinal` is `FALSE`.

A data frame containing the accumulated data from d. Note that d may be reordered in time and by cross-section and grain class.
