Data Requirements

Data Requirements

Data requirements for running MDFATE are much the same as those for

STFATE (Appendix D) and LTFATE (Appendix F). As described previously,

the user must specify ODMDS corner coordinates and interval size for grid

generation. Bathymetric data (including datum) must be provided from an

external source or automatically generated. Site locations must be identified to

specify necessary constituents for the tidal constituent program and to create the

wave time series from the WIS location of interest. Other data needs include

volume of material to be dredged, dredged material properties (i.e., composition,

voids, density, etc.), characteristics of disposal equipment, disposal duration,

water column data (density, currents), and method of disposal vessel control.

Four options exist for simulating disposal vessel control:

a. Disposal within a given radial distance of a specific geographic location

(i.e., disposal within a certain radius of a buoy). Dumps are randomly

placed with a bias applied toward the direction of approach of the

disposal vessel.

b. Disposals along transect lines identified by starting and ending

coordinates.

c. User-specified coordinates for each disposal load.

d. Prerecorded coordinates for each disposal load.

System Requirements

Recommended minimum system requirements for running MDFATE are as

follows:

a. IBM compatible 486.

b. DOS version 5.0 or greater.

c. 592 KB RAM.

d. 8 MB available hard disk space.

e. Printer capable of printing graphics (recommended).
