The Replicated Section is a quick method for adding a cross-section which has exactly the same dimensions as the cross-section immediately upstream. It can be lower or higher than the upstream section.
Data
Field in Data Entry Form | Description | Name in Datafile |
|---|---|---|
Section Label | label at replicated section | label1 |
Distance to next Section | chainage downstream to next section (m) | dx |
Bed Level Drop | drop in bed level from preceding section (m) | dz |
Easting | easting coordinate of replicated section (not used in hydraulic calculations) | easting |
Northing | northing coordinate of replicated section (not used in hydraulic calculations) | northing |
First Spill | spill label (if required) | label2 |
Second Spill | spill label (if required) | label3 |
Theory and Guidance
The Replicated Section is used to copy the preceding river or conduit section at a distance dx further along the reach and at a level dz lower.
The Replicated Section is a quick method for adding a cross-section which has exactly the same dimensions as the cross-section immediately upstream. The cross-section can be lower or higher than the one upstream. Any number of Replicated Sections can be included following each other.
General
Replicated Sections must be preceded by either a River or Conduit section (not an interpolated section). A replicated section will be the last river or conduit section in a reach if the chainage dx is given as zero.
