Data

In the case of Zero Condition the accumulated coastline change and trans­port rates are set to zero at simulation start.

In the case of Accumulated coastline you have to prepare a profile file (dfs1) with the accumulated coastline change. The file must have the same number of grid steps as the coastline file. In this case the accumulated transport rates are set to zero at simulation start and the resulting coastline position from the previous simulation should be entered into the Coastline dialog.

In the case of Accumulated coastline and transport you have to prepare a profile file (dfs1) with the accumulated coastline change, and start values of net and gross drift rates. The file must have the same number of grid steps as the coastline file. The resulting coastline position from the previous simulation should be entered into the Coastline dialog.

NOTE: A profile file with the necessary information for initial conditions can be obtained from the previous simulation by saving the results from the last time step in a separate output file of type coastline.
