Manual Forecast Display
The Manual Forecast display (see below) in the Operator Client allows for the running of single or a manually scheduled forecast.
The Manual Forecast display (see below) in a Standalone system is slightly different from the one in the Operator Client and allows for running of a single forecast or a batch of forecasts.

description
A forecast description can be entered in this field. Entering of a description is not obligatory.
Please note that the forecast name is generated automatically by the system and consists of the (i) start time of a forecast, (ii) the selected workflow and (iii) the selected What-if Scenario.
Scheduler options (only in Operator Client)
Two types of manual forecasts can be defined:
...
In case for example scheduled manual forecasts should always be made at 8:00 AM but the forecast itself should start at 12:00 PM the previous day, the Shift T~0~ should be set at 8 hours while the Start time is set at 08:00.
Batch Forecast options (only in standalone)
Two types of manual forecasts can be defined:
...
All runs will be submitted at the same time but will be run with different T0's as defined by the user.
Automatically approving forecasts
Ticking the approve box will set the status of the forecast automatically to current after it has been completed. In case you want to cancel this action or suspend it, please use the Scheduled Forecast tab in the System Monitor.
State Selection
Leaving Select initial state unchecked, the default state- as has been configured by the system manager- will be used to start the historic run preceding a forecast simulation (see also Running Modules ). For statefull simulation models- like hydrodynamic models- this means that the state selection for a model will follow the state selection rules as configured in the General Adapter Module Instances.
...
In case no Warm state can be found within the defined Search interval , the system will automatically run as if Select initial state was unchecked. This means that in that case the default state will be used for starting the historic run.
Priority
The user can give a forecast run either a High or a Normal priority. The Master Controller will give precedence to high priority tasks above normal priority tasks.
Please note that setting the priority to 'high' does not mean that the task will be directly carried out. In case other high priority tasks are waiting for execution, the new task will be added to the queue. When another task with normal priority is already being executed, it will not be cancelled when a new high priority task is submitted, but will be completed first.
Forecast length
A default forecast length is configured when setting up the forecasting system. Please note that within an area different forecasts lengths may have been configured depending on for example the hydrological (sub-) system and/or the forecasting models used.
