The initial conditions for a NAM simulation may be loaded from an existing rainfall-runoff result file by enabling ‘Use hotstart files’ and clicking on the ‘Append’ button. This will add a new row to the list of Hotstart files. Click on the ‘Browse’ button and select the required hotstart file.
Important: Initial conditions are read in the additional result files having the extension _AddNAM.res1d. Therefore, only this type of file can be selected here. The file has to be created using the ‘Create runoff hotstart files’ in the Standard results menu.
Note: It is possible to define multiple hotstart files covering different or overlapping areas. If some catchments are covered by more than one hotstart file the first hotstart file will be used. The ‘Move up’ and ‘Move down’ arrows may be used to modify the order of the hotstart files. If a catchment is not covered by any of the specified hotstart files, the initial conditions are those specified in the Catchment definitions menu.
If ‘Use simulation start time’ is enabled, the initial condition will automatically be extracted from the Hotstart file using the simulation start date and time as specified in the Simulation period page.
The date and time at which the initial conditions are loaded from the hotstart file. If ‘Use simulation start time’ is enabled the hotstart date and time will be taken as the simulation start.
