~~~~~~~~~~~~~~~~~~~~

External water use may be used for a wide range of reasons (e.g. cleaning roads, irrigating plants, fountains, washing cars).

SUEWS has two options for External Water use (if non-zero):

1) provide observed data in meteorological forcing file in the `Wuh` column with valid values by setting `WaterUseMethod` = 1 in `RunControl.nml`

2) a simple model that calculates daily water use from the mean daily air temperature, number of days since rain and fraction of irrigated area using automatic/manual irrigation. The user needs to supply coefficients (XXX) for these relations.

   a) sub-daily pattern of water use is detemined from the daily cycles specified in `SUEWS_Profiles.txt`.

   b) surface that the water can be applied to is specified by XX.

   c) water can pond.
