The following is a list of common terms you'll encounter when working with simulation.
| Term | Description |
|---|---|
Simulation layer | The resultant layer added to the Contents pane after defining the area of interest. |
Area of interest | The defined area in which the simulation will run. |
Cell size | An area of interest is evenly divided into cells prior to calculating the simulation result. The size of the cell is directly proportional to the size of the area of interest and, by default, is automatically calculated for you. For example, an 8 kilometer by 8 kilometer extent will use a 2.0 meter cell size. You can choose to override this value for a layer. Tip:To use a cell size that matches your elevation DEM resolution, your must provide a cell size that is larger than the automatically calculated cell size. |
A point location in the scene where water is introduced into the simulation. | |
Drainage | A collection of channels that have been defined for a simulation. |
A two-point linear feature that permits water to flow under the elevation surface, such as out of a dam or through a stream blockage caused by an overpass captured in the surface. | |
A linear feature that blocks the normal flow through ridges in the elevation surface. | |
Rainfall rate | The amount of rain that would fall over a given interval of time if the rainfall intensity were constant over that time period. |
Transition time | The time to be used changing between two rainfall rates. |
Infiltration rate | The rate soil can absorb water. |
Maximum infiltration | The maximum allowable infiltration rate. Once reached, water is no longer able to be absorbed and instead continues to move downhill. |
