There are various settings available on the Settings tab. The Settings can be saved for use as future defaults using the 'Save Default Settings' button.
Most settings are self explanatory, however, the more important ones are:
Some of the important general settings are:
|•||Very Short Duration Events|
No temporal patterns are included in the ARR Data Hub for durations of 5 mins or shorter. If this checkbox is selected then Storm Injector will create storms with 1 time step equal to the duration and deposit 100% of the rainfall depth in that timestep.
|•||Pause between model runs|
For hydraulic models that require hardware dongles to run (particularly network dongles), it may be necessary to insert a pause between model runs.
|•||Downloading from Web|
The top two checkbox indicate that the user has accepted the BoM conditions and caveat for automatically downloading IFD data. The Show Browser checkbox determines if the web browser will wait for the user to click Ingest Data before processing the data or if it will process automatically. The loading time governs how long the program should wait before trying to read the data. If downloading data is causing errors or you have a slow connection, you should try entering a larger loading time.
Users will need to enter the path of the hydrologic engine they would like to use.
In the case of XP-RAFTS, this file is called 'raftsEngW.exe'.
Also ensure that the Job Control and individual nodes are setup to export total hydrograph files (*.tot) to allow plotting of hydrographs in the software.
In the case of WBNM, it is suggested that the new slim engine is utilised. This file may be called: file wbnm_eng_w64.exe
Also ensure that WBNM is setup to export metafiles to allow hydrograph export (out_metafile=.TRUE. to allow hydrographs)
In the case of RORB, please select the command line version of the engine. This may be called RORB_CMD.exe
There are numerous methods available to calculate the initial loss for a storm. These include using the global initial loss from the ARR Data Hub or subtracting the corresponding preburst depth.
The initial and continuing loss rates can also be overridden if required. Pre-burst subtractions are still made to the Override Initial Loss if selected.
The initial loss (before any pre-burst adjustment) can also be reduced by a given percentage. This is designed to allow implementation of reduced initial loss for urban catchments as per Book 5 Section 126.96.36.199.1.
Impervious loss rates are also assigned in these settings.
Users may choose how a adopted temporal pattern for a given duration and subcatchment is selected. The options include the first exceeding the median (or median if odd number of patterns), first exceeding mean or the closest to the mean with a preference to those above the mean. For example, a bias factor of 2 would mean that a temporal pattern yielding a peak flow less than the mean would need to be half the 'distance' to the mean that the nearest result exceeding the mean before it would be selected.
For storm of durations of 1-5min, users may elect to have single timestep storms added or not using the 'Add single timestep events for 1 - 5 min checkbox.
Various utilities can be linked via the Settings to help integrate Storm Injector with other products these include:
|•||convert_to_ts1.exe - This utility is used to convert hydrograph output files to ts1 format for TUFLOW|
