Characteristic parameters

Explanation of characteristic parameters

This table provides the user with a direct link to the explanation of the module that extracts the characteristic parameter from the coastal profile. Thus, it provides an explanation of the precise method used to derive each characteristic parameter.

Variable names and dependencies of characteristic parameters

This table shows the variable name of each characteristic parameter that is used in the jarkus.yml file to indicate which characteristic parameters should be extracted. Additionally, the corresponding variable names of the output that is produced for each characteristic parameter is given. The last column provides on which variable the extraction of the characteristic parameters depends. For instance, the mean sea level can only be extracted when the dune top location had already been extracted because the cross-shore location of the primary dune top is necessary. These dependencies are also indicated in the Functionalities with the See also sections.
