Abstract |
The SCREEN Model estimates the maximum ground-level concentration for sources in simple flat or elevated terrain, accepts user-specified distances, performs inversion break-up and shoreline fumigation estimates, includes building downwash effects in the wake region and performs calculations for the cavity region, and includes an optional complex terrain screening procedure based on the VALLEY Model 240 hour screening technique. SCREEN operates on IBM-PC compatible systems with at least 256K of RAM. Software Description: The program is written in FORTRAN for implementation on IBM-PC compatible systems, using DOS operating system. Minimum of 256K of RAM. |
