A decision maker (the end user of the system) wants to evaluate changes in vegetation in some geographical region over a long time period caused by some short term disturbances such as a fire or human's activities. |
One of the critical parameters of the vegetation model (EDYS) is soil condition at the time of the disturbance. |
This in turn is dominated by rainfalls that possibly occur at that time (CASC2D simulation) |
Input data for the simulations are available from the Internet, such as Data Elevation Models (DEM) from USGS web site or from custom databases (spieces characteristics) |
