A map layer shows all catchments, which can be clicked to show a popup including a hyperlink to the full details.
Opening details of a catchment will show you the number of sub-catchments, the length and associated roads, for example. In addition, all entities, such as floods or spills etc, associated with the catchment can be seen, along with an audit log of edits to catchment details.
All catchments can be viewed in a summary grid, accessed from the Main Menu > Drainage Catchment Model > Catchments Summary
