 : The project is configured with a grid size of 2m. This means the entire [[project area]] is divided up into cells of 2m by 2m. Each cell has discrete properties based on the present features, such as a single terrain height and a single water height. For most calculations, this is a high enough accuracy to calculate with, as only the effects of features smaller than 2 meters may be diminished. In timesteps of less than a second per step, calculations are performed for each cell on how much water can move to others cells. More information on grid calculations:

	: Rainfall is calculated through a series of steps across the entire project area. This makes it difficult to provide a perfect description on how to fine-tune the calculation time for arbitrary projects, although some general rules-of-thumb exist. Setting a longer simulation time, having more water in the ~~3D world~~, and a more accurate grid size to perform the calculations on, will require more time to compute. Reducing the accuracy, excluding irrelevant sections from the calculation, and limiting the amount of calculations running in parallel are common ways to speed up the computation.

	: Water is affected in subtle and less subtle ways by a large number of factors: the slope of the terrain, the roughness of the ground, the amount of water and the direction it moves in, just to name a few. It's difficult to provide a single answer to intuitively explain all ~~phenomenons~~ you may see in regards to water flow and retention. What does help is to look for signs that water is flowing towards or away from any place you wish to inspect more closely, and to take into account continued precipitation, evaporation, and infiltration (although infiltration is explicitly disabled for this demo).
