Option 1: Universal asignment for all 1D corner nodes.

Option 2: Assignment by specified 1D node.
1
N
+
Corner 1D node number
2
WIDTH(N)
+
Channel width at specified nodes (feet or meters).
3
SS1(N)
+
Left side slope at specified nodes (inverse bank slope).
4
SS2(N)
+
Right side slope at specified nodes (inverse bank slope).
5
WIDS(N)
+
Width - off channel storage (feet or meters).
6
WSCRIT(N)
+
Optional Critical water surface elevation above which off-channel
storage becomes active (feet or meters)
7
SSS(N)
+
Optional inverse bank slope of off channel storage
NOTE: Units depend upon SI card designation.
NOTE: If fields 6 and 7 are omitted, the off-channel storage is assumed to have a rectangular cross-section, with the
bottom elevation being equal to the elevation of the node.
NOTE: The inverse bank slope can be defined as follows: If the slope of a line is defined by the ratio of the vertical
displacement to the horizontal displacement (i.e. "rise over run"), the inverse bank slope is the value of the
horizontal component of the slope if the vertical component is set equal to 1. For example, a slope of 2/5 can be
expressed as 1/2.5, where 2.5 is the inverse bank slope.
