TUFLOW HR Output: Difference between revisions

For the HR output, the water level at each HR output location is interpolated from the computed 2D water levels. The depth is the difference between the interpolated water level and the sub-grid elevation. This differs from the standard depth output which calculates the depths at cell centres and corners first, then interpolates the depths to the standard output grid locations (default is half the cell size). The difference between the standard (left) and HR (right) depth interpolation processes is illustrated below.
