Attribute	Unit	Description
EVAPORATION_M	end-time, m	An array of values, each pair indicating until what time that period of evaporation will last and what amount evaporates in that period.

A maximum of 10.000 values (5.000 pairs) can be defined.
Internally each period with amount values are converted to an evaporation rate per second at a particular time in the simulation.
The default value is set to 0.125 mm in 2 hours (0.000125 m in 7200 seconds), which corresponds to 1.5 mm per day. This value is derived from the theory described in 2.3 Gewasverdamping^[1] in the book Grondwaterzakboekje, which combines the formula of Makkink with a temperature dependent factor (which is approximately linear between 0 and 24 C). Based on the plotted lines, it was selected as an average of march, june and september, for a cloudy rainy day, which corresponds to a heavy rainfall event.
