Precipitation

Precipitation is the measured rainfall. You can specify the precipitation as a rate, for example in [mm/hr], or as an amount, for example in [mm]. If you use the amount method, MIKE SHE will automatically convert this to a rate during the simulation.

If you use a rate, then the EUM Data Units (V1 p. 135) must be “Precipitation” and the time series must be Mean Step Accumulated (V1 p. 150).

If you use an amount, then the EUM Data Units must be “Rainfall” and the time series must be Step Accumulated (V1 p. 149).

The Precipitation Rate item comprises both a distribution and a value. The distribution can be either uniform, station-based or fully distributed. If the data is station-based then for each station a sub-item will appear where you can enter the time series of values for the station.
