Detailed Description

simulates the water cycle on a ResourceUnit.

The WaterCycle is simulated with a daily time step on the spatial level of a ResourceUnit. Related are the snow module (SnowPack), and Canopy module that simulates the interception (and evaporation) of precipitation and the transpiration from the canopy. The WaterCycle covers the "soil water bucket". Main entry function is run().
