+As mentionned earlier, most of the simulation parameters are copied from the template ``.inp`` file.

+Remaining default parameters are currently hard coded in the views within the database ``qgep_swmm`` schema. 
+The defaults parameters can be edited directly in the view (with PgAdmin).

+    The default parameters modified in the views and modified views in general will be overwritten during a datamodel update.
