Figure 2- "Merge Catchments..." option from the Tools menu
In the “Merge Catchment” window, the name of the source scenario is specified, and it is possible to select the target scenario from the drop-down menu (if the catchment project consists of more than 2 scenarios). Also, in this window, it is possible to choose a prefix for the name of all the sub-catchments, nodes, and links that are going to be transferred from the source scenario to the target scenario, the default prefix is “copied”. If two merged scenarios have nodes or links with the same name, this prefix helps to identify which one is related to the source scenario (name with the prefix “copied”) and which one is related to the target scenario. Finally, by clicking on the “Merge Catchments” option, the merging process is done (Figure 3). A list of all transferred elements with their previous and new names, including the names of nodes, links, sub-catchments, elements related to the constituent model, and functional units which are added to the target scenario, will be presented in this window. Finally, the message “Merge Complete” indicates the end of the process and this window can be closed (Figure 3).
