Rainfall events, also referred to as storms, are the most common inputs that you add to your models.
00:09
There are two main types of rainfall data that can be used in InfoWorks ICM: Observed and Design.
00:17
Observed (or recorded) rainfall data represents actual rainfall events.
00:22
These events can cover a single storm or multiple storms over a long period of time.
00:28
Recorded rainfall data is normally used to calibrate the model
00:32
and verify its correct operation against data collected during flow surveys or against flood records for large historical storms.
00:40
Design rainfall storms represent the statistical characteristics of rainfall.
00:45
They are derived from the analysis of many years of actual rainfall records.
00:49
They are simpler to use than observed rainfall and can approximate a region's rainfall in just a few storms.
00:56
In this tutorial, you create or import both types of rainfall events in the model, starting with Design Rainfall.
01:04
Before importing an inflow event, it is a good idea to create a new model group to store all your event data.
01:12
Right-click your existing Model Group and select New InfoWorks > Model Group.
01:17
In the New Name – Model Group popup, name the group “Ancillary Files” and then click OK.
01:26
From the Model Group, right-click the Ancillary Files group and select New InfoWorks > Rainfall Event.
01:35
In the New Name - Rainfall event popup, enable Generate Design Rainfall, and add a name of “M5-60”.
01:40
Click OK.
01:45
In the Select an Event Generator popup, select United Kingdom Rainfall for the purposes of this tutorial.
01:53
In the Rain Event Generator Parameters dialog box, in the Event group,
01:57
set the Return period to 5 for 5 years, and the Duration to 60 for 60 minutes.
02:04
Then, expand the Profile drop-down and select Summer.
02:08
Click OK to save your changes.
02:11
In the Ancillary Files group, right-click M5-60, and select Open As.
02:17
From the Select Format popup, select Grid Editor, and then click OK.
02:22
The Rainfall event for the M5-60 storm appears in a grid format.
02:28
You can see there are tabs for setting the antecedent conditions.
02:32
These supersede any settings in the model or sub-event properties.
02:36
When you are finished reviewing the data, click Close.
02:40
You can also view the design rainfall data in a graph format.
02:44
Right-click M5-60 again and select Open As.
02:49
From the Select Format popup, select Graph, and then click OK.
02:54
You can resize the graph window to better read the results.
02:59
Close the graph window.
03:01
The other type of rainfall is observed rainfall.
03:05
Frequently, rainfall data is contained in a spreadsheet.
03:09
Right-click Ancillary Files and select Import InfoWorks > Rainfall event > from Infoworks format CSV file.
03:18
Navigate to the folder with the downloaded files for this tutorial and select 2001 Typical Year_Evap.csv.
03:28
Click Open.
03:30
Again, you can view the rainfall in graph form by right clicking the event and selecting Open as > Graph.
03:39
You can also right-click the event and select Open as > Editor.
03:46
The Rainfall Event profile has a column header of 1 (mm/hr).
03:51
This means the rainfall will be applied to those subcatchments with a Rainfall Profile of 1.
03:57
Note the tabs at the bottom of the window such as Evaporation Data.
04:01
These can be used to set additional parameters such as time-varying evaporation profiles that will be used during the event
04:08
or to set individual starting conditions for individual surfaces.

Rainfall events, also referred to as storms, are the most common inputs that are added to ICM models. There are two main types of rainfall data that can be used in InfoWorks ICM: Observed and Design.
Observed—or recorded—rainfall data represents actual rainfall events. These events can cover a single storm or multiple storms over a long period of time. Recorded rainfall data is normally used to calibrate the model and verify its correct operation against data collected during flow surveys, or against flood records for large historical storms.
Design rainfall storms represent the statistical characteristics of rainfall. They are derived from the analysis of many years of actual rainfall records. They are simpler to use than observed rainfall and can approximate the rainfall of a region in just a few storms.
In this tutorial, both types of rainfall events are created or imported in the model.
Before importing event files, it is a good idea to create a new model group to store all event data.
To create a design rainfall event:
The Rainfall event for the M5-60 storm appears in a grid format. Note the tabs for setting the antecedent conditions. These supersede any settings in the model or sub-event properties.
The design rainfall data can also be viewed in a graph format.
To import an observed rainfall event, which is frequently contained in a spreadsheet:
The Rainfall Event profile has a column header of 1 (mm/hr). This means the rainfall is applied to subcatchments with a Rainfall Profile of 1. Note the tabs at the bottom of the window, such as Evaporation Data. These can be used to set additional parameters such as time-varying evaporation profiles for use during the event, or to set individual starting conditions for individual surfaces.
