In this model I add another simple water pump by simply copying the code for the existing water pump and changing the X coordinate.
This is a model of a simple water pumping model, which has the ability to track the amount of groundwater and atmospheric water. There is a small chance that the rain drops will evaporate (get smaller) as they fall through the sky.
The user is able to change the amount of initial water.
Possible Extensions-
adding a slider to change the amount of evaporation.
