	This setup demonstrates that water will flow from a location with a higher water level to a location with a lower water level, if there is a path the water can take. If a construction allows water to flow through and the water level is high enough to reach it, water can and will flow through. When that is no longer true, the flow of water stops.

	What you'll notice specifically is that the calculation's results is composed of 10 timeframes. Each of the timeframes represents a snapshot of the process of water flowing into the deeper hole. However, the water flows so quickly that even at the first timeframe most water has already flowed into the lower hole. This means the timescale of the simulation should be tweaked as well.

	Knowing how large our project area is, and how much water is actually placed in the project area, we can calculate the amount of cells the project area is divided into, and the amount of cells which are actually used.

	To calculate the amount of cells in the project area, we can take the size of the map (500 meters by 500 meters) and divide it by the grid cell size (which is 10 meters by 10 meters, by default). This tells us the project area is divided into 50 by 50 = 250 cells.
