Converting MOUSE Natural Channels into InfoWorks ICM Channel
Sections
MOUSE provides a link type of 'Natural Channel'. The natural
channel is given a topography ID. The topography ID is linked to n number
of cross-sections which can be specified along the length of the link.
Cross-sections are provided at various lengths along the natural channel,
including length 0.0 and the length of the pipe.
The MOUSE cross section data for natural channels is imported into InfoWorks ICM as follows:
- InfoWorks ICM creates a channel link for each cross-section excluding the last section, with the channel links separated by break nodes.
- The Cross Section data is imported into the Channel X Coordinate and Depth arrays of the InfoWorks ICM Channel shape grid. Depths are adjusted so that there is a 0.0 value in the InfoWorks ICM cross-section data e.g. if the lowest depth is 10.0, then subtract 10.0 from all depths.
- The MOUSE topography parameters are applied to the length of the channel link (rather than being interpolated with the next cross-section as is the case in MOUSE). In MOUSE, roughness is provided for the top and the bottom of the channel, whereas in InfoWorks ICM, roughness varies across the channel. InfoWorks ICM will take the mean of the top and bottom roughness and apply this to the channel.
- The first channel link will be given the upstream headloss coefficient of the MOUSE upstream manhole, provided that the coefficient is the total headloss coefficient (see Note on Headloss Coefficient Calculations) and the last link will be given the InfoWorks ICM default downstream headloss coefficient. All upstream and downstream headloss coefficients in between will be given a headloss type of 'fixed' and a value of 0.0 as the links inbetween are purely artificial.
