FAQ

Why does water sometimes stop and then resume flowing across the terrain?

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. In the case of a flooding, by far the greatest factor is the elevation, and the impulse of the water. For a more detailed insight into the how water behaves in any particular location, especially where the flow speed varies, the measuring tool can be of help. Use the line mode of the measuring tool and create a measuring line across the location where water flow stops and later resumes. It's very likely that you will find that the water is blocked by an elevation of the terrain, until the water level has increased to the point where it can flow over the barrier.

Are there more options for mitigating the effects of a flooding?

Currently, only 1 simple option to affect the calculation is available. In reality (and in the Tygron Platform), more spatial actions exist such as the creation of canals or retention ponds, or changing the configuration of hydraulic structures allowing more or less water to flow through.

How does any particular setting affect calculation time?

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.
