Storm Injector Help

 

Storm Injector includes default temporal patterns for all 3 of the major PMP estimation methods for Australia.

 

Rainfall depths should be calculated outside Storm Injector and imported via IFD csv files. CatchmentSIM can be used for rainfall calculations and spatial distribution for the GSDM method, a tutorial can be found here.

 

Example IFD Location templates can be downloaded from the following links. You may need several of these (assigned to subareas based on proximity) to represent any spatial variation in the rainfall.

•GSDM

•GSAM

•GTSMR

 

PMP Storms are modeled in Storm Injector as custom events, which are entered into the Custom Events field as shown below. Multiple events can be comma separated.

 

 

Right click on the Custom Events field will bring up a pop up menu with some examples of Custom Events including PMP events.

 

An example of a custom event is:

 

CStm_GSDM_PMP(GSDM)_1% AEP_HUB DATA_0_0_1.0$PMF GSDM$

 

This can be broken down (underscore separated) as follows:

•CStm: this tag informs Storm Injector that we are applying a set of custom temporal pattern for various durations as listed in the Custom Temporal Patterns panel on the settings tab

•GSDM: this should match the first column in the Custom Temporal Patterns panel on the settings tab

• PMP(GSDM): this is the column header for the rainfall depth for the various durations for all IFD Locations (it is important that all IFD Locations selected in the IFD Location column in the Project Setup tab have a depth column with a matching header). An example CSV that can be imported can be downloaded here. CatchmentSIM can be used to automatically create PMP average weighted depth IFD Locations for each subcatchment. The latest CatchmentSIM PMP GSDM marcro script can be found here (copy this into your CST\PMP (GSDM) directory).

•1% AEP: this tag relates to the Initial Loss (pervious) that should be applied. It can be a ARR16 event name (to use the IL from the Storm Burst loss table), ARR87 to use the ARR87 initial loss from the settings tab or a specific numerical value

•HUB DATA: this tag relates to the Continuing Loss that should be applied. It can be HUB DATA to use the value from the ARR DATA HUB or ARR87 to use the ARR87 continuing loss from the settings tab or a specific numerical value

•0: Any depth adjustment, for example 20 would be a 20% increase

•0: Any IL adjustment, for example -20 would be a 20% decrease

•1.0: The ARF to apply. It can be a ARR16 Event name to use the value from the Areal Reduction Factors table or a specific value. A value of 1.0 means no ARF adjustment will be applied.

 

More specific advice for each of the 3 main PMP methods is shown below.

 

Generalised Short Duration Method (GSDM)

 

A GSDM example has been presented above.

 

A full tutorial of GSDM PMP modelling including spatial distribution using CatchmentSIM and Storm Injector can be viewed here.

 

Generalised southeast australia method (GSAM)

 

A GSAM version of the PMP can be applied similarly with a Custom Event such as:

 

CStm_GSAMInland100_PMP(GSAM)_1% AEP_HUB DATA_0_0_1.0$GSAMInland100$

 

This event can be broken into the same components as the GSDM example presented above except it is using IFD depths with a header of PMP (GSAM) and the custom temporal patterns labeled GSAMInland100 (100 km2 standard area) . Temporal patterns for Coastal areas or other standard areas can be accessed by changing these labels accordingly with reference to the Custom Temporal Patterns table.

Furthermore, if you wish to apply a GSAM Pre-Burst temporal pattern, you can setup the pre-burst injection panel in the Settings.

 

 

Generalised tropical Storm Method (GTSMR)

 

Storm Injector supports application of both the normal AVM temporal patterns of the GTSMR method as well as the historical ensembles. Example of Custom Events for both categories are shown below

 

GTSMR AVM and Historical temporal pattern ensembles can also be applied, examples include:

•AVM Pattern: CStm_GTSMRCoastalAVM40000_PMP(GTSMR)_1% AEP_HUB DATA_0_0_1.0$GTSMRCoastalAVM40000$

•Historical Ensemble: CStm_GTSMRCoastalHist40000_PMP(GTSMR)_1% AEP_HUB DATA_0_0_1.0$GTSMRCoastalHist40000$
