Profile Properties Dialog

The Profile Properties dialog is displayed by right-clicking on a profile in the Event Editor and selecting Profile properties from the popup menu. The fields in the dialog define various aspects of an event profile.

The properties in the dialog vary depending on event type.

Used by InfoWorks and SWMM networks.

The local parameters for the profile override values set for the sub-event. Different local values can be defined in the profile for each sub-event.

Leave these values blank to use the sub-event values.

Evaporation properties defined in the rainfall profile properties will be overridden if an Evaporation profile is entered in the Evaporation Page of the Rainfall Event Editor.

The order of precedence for values for local parameters is as follows. If a value exists, and the other conditions are met, InfoWorks ICM will use the first available value from the following list:

  • from the Evaporation Page of the Rainfall Event Editor (evaporation only)
  • from the rainfall profile properties
  • for InfoWorks networks only - from the current rainfall sub-event (if this is a second or subsequent sub-event), as long as the Read Subevent UCWI & evaporation check-box is checked on the Schedule Hydraulic Run dialog.
  • from the first rainfall sub-event

Values must be defined in the first sub-event, otherwise values of zero are assumed.

Calibration / areal reduction

This field has two uses depending on whether the storm is a design storm or observed.

Design

Field shows the areal reduction factor appropriate for the catchment area and storm duration. This is calculated automatically by the rainfall generator program, but can be altered by the user if required

Observed

Field shows the calibration factor to allow for errors in the gauge calibration. All rainfall intensities for the gauge are multiplied by this factor

In most urban drainage catchments, the areal reduction factor will be greater than 0.9 and the variation will not be large between different catchments.

Local antecedent depth

This is the rainfall depth in mm that has fallen in the hour immediately prior to the storm. The software uses this figure to calculate how much of the depression storage has been taken up before the storm begins.
Local evaporation

Rate of evaporation.

This value will be overridden if an Evaporation profile has been defined on the Evaporation Data Page of the Rainfall Event Editor.

Local UCWI

InfoWorks networks only.

This defines the antecedent wetness of the catchment for the Wallingford runoff model.

Local New PR API30

InfoWorks networks only.

API30 for use with the New PR (New UK) runoff model.
Local Horton SMS The Soil Moisture Store representing the initial wetness of the catchment for use with the Horton runoff model.
Local Green-Ampt SMD The soil (initial) moisture deficit is the fraction difference between the soil porosity and actual moisture content, expressed as a percentage. For use with the Green-Ampt runoff model.

Local SCS index

InfoWorks networks only.

This defines the catchment wetness for use with the SCS, CN and CNSWMM runoff volume models. The default value is 2.

Value Description

1

Dry Catchment

2

Average Catchment

3

Wet Catchment
Local ReFH soil moisture

InfoWorks networks only.

Initial soil moisture content, Cini, for use with the ReFH runoff model.
Catchment ReFH baseflow BF0

InfoWorks networks only.

Initial baseflow, BF0, for use with the ReFH runoff model.

When calculating the initial baseflow in a subcatchment during a simulation, the BF0 value specified in this field will be scaled by the ratio of a subcatchment area to the catchment area, i.e the initial baseflow is proportional to subcatchment area.
Catchment area The size of the catchment area. Note that the size of the catchment area is defined in the Rainfall Generator dialog.

Profile title

 Name of the Rainfall Profile.

Profile description

A descriptive title for the profile. This is just for information. The Profile title is used when using rainfall with a simulation.

Gauge data

Contains boundary data if a rainfall area is applied to the profile.

Avoid attempting to edit this data by hand.

See Spatially Varying Rainfall for more information.
ReFH ACF ReFH adjustment coefficient calculated by the rainfall generator for selected season and return period.
Snowmelt SCF

Snow Catch Factor (SCF) . When temperature falls below the Dividing temperature between snow and rain (defined in the User Defined Defaults), the values on the rainfall TVD tab are assumed to be snow fall.

Enter a Snow Catch Factor to be used as a multiplying factor to account for snowfall that may not be captured by rain gauges. If an SCF is not defined, an SCF of 1.0 will be assumed.

Used by InfoWorks and SWMM networks.

Evaporation Profiles defined in the Evaporation Data Page of the Rainfall Event Editor, will override evaporation values set in the Rainfall sub-event and profile data.

If there are no evaporation profiles defined, the evaporation values on the sub-event and profile data will be used.

Note

If an evaporation profile starts after the Rainfall Event start time, evaporation of 0 mm/day will be assumed until the evaporation profile start time. If the Rainfall Event lasts longer than the evaporation data, the evaporation will drop to 0 mm/day one evaporation timestep after the end of the evaporation data.

Profile ID

Name of the Evaporation Profile.

  • If the evaporation data consists of one profile only, the evaporation rate on that profile is applied to all rainfall gauges in the event.
  • If the evaporation data consists of more than one profile, the evaporation Profile IDs must match the Rainfall Profile IDs. The number of profiles must equal the number of rainfall profiles in the event.

Profile title

Object Reference

Object reference at which the inflow enters the system. A value must be given.

Inflow hydrographs can be applied to:

  • Nodes - inflow is applied at the referenced node. If the referenced node is an outfall, inflow will be ignored.
  • Links - inflow is applied laterally to the link. If the object referenced is a control, the inflow will be assigned to the upstream node of the control, unless that node is an outfall, in which case the inflow will be ignored. If the object referenced is a bridge link, inflow is applied laterally to the contraction reach. (InfoWorks networks only)
  • 2D Point Sources (InfoWorks networks only)
  • 2D Line Sources (InfoWorks networks only)
  • 2D Boundaries
Note

If a 2D Boundary Condition has the same ID as a node in the network, the inflow hydrograph will be applied to the node.

Descriptive Title

Title of the profile

Used by InfoWorks and SWMM networks.

Node Reference

The node reference at which the software applies the level hydrograph. A value must be given. For level hydrographs this must be an outfall node.

When carrying out 2D modelling, the node reference field may be used to reference a 2D Boundary.

Pipe Level or Datum

There are parameters for the profile that override values set for the sub-event. These are:

  • Initial Soil Saturation
  • Initial Groundwater Level

Different local values for these two parameters can be defined in the profile for each sub-event.

Leave these values blank to use the sub-event values.

Subcatchment/ground ID

If a Subcatchment ID (which uniquely identifies a particular subcatchment in the network) is specified, then the specified subcatchment will use the profile, specified in this dialog, to set initial soil saturation and groundwater level.

If a Ground infiltration ID (which identifies a Ground infiltration record) is specified, then all subcatchments associated with this Ground infiltration record (ie the subcatchments' Ground infiltation ID parameter is set to this ID), will use the profile specified in the Ground infiltration record to set initial soil saturation and groundwater level.

Note that the Subcatchment ID always has precedence. Therefore, if specified ID matches both a subcatchment and a ground infiltration record, the profile specified in this dialog will be used to set initial soil saturation and groundwater level for the specified subcatchment. Similarly, if you have a profile with a ground infiltration ID that is used by a subcatchment that also has a profile in the same ground infiltration event, then the subcatchment will get its initial soil saturation and groundwater level from the subcatchment profile.

Initial Soil Saturation (%)

Required value. The initial soil saturation for the subcatchment (which overrides the global initial value given in the sub-event properties).

Initial Groundwater Level

Required value. The initial groundwater level for the subcatchment relative to the model datum (which overrides the global initial value given in the sub-event properties).

Descriptive Title

A descriptive title for the profile. This is just for information. The profile number is used when using infiltration with a simulation.

Used by InfoWorks and SWMM networks.

See the Regulator Event topic for further details on the use of direct and indirect regulator profiles.

Reference

The regulator or, InfoWorks networks only, the RTC table that the profile applies to:

  • Regulator ID if Profile type is Direct.
  • RTC table name if Profile type is Indirect. The reference should take the form RegulatorID.TableName for tables defined in regulators, or TableName for tables defined in the Global section of the RTC.
Measured variable

The applicable measured variable option can be selected from the dropdown list:

  • None (default) - this must be used by SWMM networks
  • the regulated variable when Profile type is Direct
  • the RTC table output variable when Profile type is Indirect
Profile type

The applicable profile type option can be selected from the dropdown list:

Direct

Profile is used to directly control a regulator.

The values in the profile represent the measured values of the regulated variable and will replace RTC (if present).

Linear interpolation is used between subevent timesteps (except for pump state where no interpolation is applied between timesteps).
DirectStep

Profile is used to directly control a regulator.

The values in the profile represent the measured values of the regulated variable and will replace RTC (if present).

No interpolation is applied between subevent timesteps.
Indirect

InfoWorks networks only.

Profile provides indirect control of a regulator by providing a time series of measured variables used in RTC tables.
Behaviour between subevents

Used by InfoWorks networks only.

The applicable behaviour between subevents option can be selected from the dropdown list:

Extend

Before the start of the first subevent, profile values will be set to zero.

The value at the last timestep of a subevent will be applied until the first timestep of the next subevent.

The value at the last timestep of the last subevent will be applied until the end of the simulation.
Linear

Before the start of the first subevent, profile values will be set to zero.

Linear interpolation of values will be carried out between subevent timesteps.

The value of profiles one timestep after the end of the last subevent will be set to zero
Use RTC

RTC will be applied:

  • Before the first timestep of the first subevent
  • Between subevents
  • After the last timestep of the last subevent

The properties displayed on the dialog depend on whether the profile is a sediment fraction profile, dissolved pollutant profile, or an attached pollutant profile.

Object Reference

The label identifying the object at which the profile is applied. The object must have a corresponding inflow or level hydrograph. A value must be entered here.

Pollutograph profiles can be applied to:
Profile Type

Profile type can be one of the following:

  • Suspended (default) - profile defines the suspended load concentration in the boundary
  • Bed load - profile defines the bed load concentration in the boundary

If unspecified, a value of Suspended will be assumed.

(Applicable to Sediment fractions only)

Sediment Fraction Name

The name of the sediment fraction to which the pollutant is attached. Enter either SF1 or SF2

(Applicable to Dissolved Pollutants only)

Pot. Fact. of Sed. Fract.

Potency factor of sediment fraction. The mass of the pollutant for a particular sediment fraction is derived by multiplying the sediment mass by the potency factor for a particular pollutant.

(Applicable to Dissolved Pollutants only)
Sediment Fraction

The name of the sediment fraction to which the pollutant is attached. Enter either SF1 or SF2.

(Applicable to Attached Pollutants only)

Used by SWMM networks only.

Node ID

The identifier of the node that this profile is applied to.
Type

The type can be one of the following:

  • MASS
  • CONCERN (concentration)

If unspecified, a value of MASS will be assumed.

Units factor

(deprecated)

A factor for converting values into the selected units.

Default is 1.

Note

This property is now deprecated but retained for backwards compatibility. It has been replaced by the Mass units factor in a node's Pollutant inflow property.
If a Units factor and a Mass units factor are specified, and both are set to a value other than 1, then both factors will be applied to the relevant pollutant inflow value for the applicable node during a simulation or when they are exported.

Tip

Use the Mass units factor in a node's Pollutant inflow property rather than this Units factor field to specify the required factor.
