=Interpolation near Thin Breaklines =
Thin breaklines are often used to define hydraulic controls, such as levees and road embankments. These controls often experience upstream controlled weir flow, where the water levels on the two sides of the breakline can be considerably different. Retaining just one water level (upstream, downstream or average) at output points along the breakline may result in unsatisfactory water level map output as illustrated in the two figures below. This issue becomes more profound the larger the 2D cell size.

'''HR Thin Z Line Output Adjustment == ON CELL SIDES (left) and ON ALIGNMENT (right)'''
▲Note: this feature (at present) only works for thin breaklines in Z Shape (2d_zsh) layers. Thick/wide breaklines raise more than 1 row of cell centres and 2 rows of cell faces, and thus do not experience this HR interpolation issue.
