Sub-Event Properties Dialog

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

Level, depth, flow and velocity data

Field

Description

Event Reference Number

Reference number for the event

Start Date

The start date of the sub-event

Start Time

The start time of the sub-event

Timestep

This is the interval between each reading. This is constant throughout the sub-event.

The Time Step is entered in the format <n>[<u>], where <n> is an integer greater than zero and <u> is an optional unit specifier (representing seconds, minutes, hours and days respectively), e.g. 10m = 10 minutes.

If <u> is not specified, a unit of seconds is assumed.

No. of hydrographs

Number of profiles

The number of rain-gauges for which data is given in the event. This must be constant throughout the event

UCWI

Urban Catchment Wetness Index for use with the UK Urban Catchment Runoff Model. Local UCWI can be defined for each profile in the Profile Properties Dialog.

Antecedent rainfall depth

The rainfall depth that has fallen in the hour immediately prior to the storm. Local antecedent rainfall depth can be defined for each profile in the Profile Properties Dialog.

Evaporation

Rate of Evaporation for sub-event. Local rate of evaporation can be defined for each profile in the  Profile Properties Dialog.
