For the case of sand and silt and the steeper foreset slope, the time to emergence is 0.35 years; however, this is probably too optimistic. The more realistic estimate is probably in the range of 5 to 15 years. This case illustrates the sensitivity of the results to sand discharge and the associated slope.
