Line 96: =Showing Face Elevation in HR_Z Check File = When modelling breaklines in TUFLOW, thin breaklines modify the cell face elevations but do not modify the cell storages (see Section 7.2.6.2). When outputting the high-resolution outputs, the user can set whether the cell face elevations are included using the following .tcf command. The default is ON, to use face elevations to indicate whether water can flow through the face or not. 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 Grid Output Use Face Elevations == {ON} \| OFF {{Tips Navigation
