What is the difference between PRMS Storm and Daily modes?

Watershed response can be simulated at both a daily and a storm time scale. In the daily mode, hydrologic components are simulated as daily average or total values. Streamflow is computed as a mean daily flow. In the storm mode, selected hydrologic components are simulated at time intervals that can range from less than one to 60 minutes. The time step must be constant within a storm but could be different for each storm. Continuity of mass is maintained as the model moves from daily mode to storm mode and back to daily mode. Storm hydrographs and sediment yields for selected rainstorms can be simulated in storm mode. Sediment modeling capabilities are provided only in the storm mode.
