=Water Level Interpolation Method=
The corner water level interpolation methods for the standard output (Map Output Corner Interpolation ==) applies a minimum corner water level of “corner elevation + cell wet/dry depth” if all the surrounding 4 cells are wet. However, this may produce “bumpy” water level outputs along narrow streams in a direct rainfall SGS model between sheet flow cells and fully wet cells when using the new high resolution output. This is caused by applying a linear water level interpolation between SGS cells that have a non-linear minimum SGS elevation as illustrated below.
interpolated from the surrounding SGS sampled elevations.
