Graph Key

Nodes of different colours represent the following:

Solid arrows point from a submodule to the (sub)module which it is descended from. Dashed arrows point from a module or program unit to modules which it uses.
Where possible, edges connecting nodes are given different colours to make them easier to distinguish in large graphs.

~ ~ ~ ~ ~ ~ END SPECIFICATIONS ~ ~ ~ ~ ~ ~ If side slope is not set in .rte file then assume this default If it is main reach default side slope to 2:1 if it is a waterway default to 8:1

check if bottom width (b) is < 0 compute flow and travel time at bankfull depth compute flow and travel time at 1.2 bankfull depth compute flow and travel time at 0.1 bankfull depth
