junction nodes at Junction 1, and Nodes 15, 16, and 21 are junction nodes at 

 Junction 2. Channel 1 has six nodes beginning at the sea boundary at Node 1 

 and ending at Junction 1. Channel 2 has six nodes beginning at Node 7 at 

 Junction 1 and ending at Node 12 in the bay. Channel 2 was terminated at Node 

 12 because a tide gage was located at this node, making it convenient to use 

 as an external boundary condition (a node at which data are introduced to 

 drive the model) . Node 7 becomes an internal boundary node because it defines 

 the boundary of Channel 2, but is in the interior of the inlet system. The 

 number of nodes of each channel, and their relationship to the junctions and
