    I actually set an initial condition hydrograph. Completely forgot about the logic of the floodwave that there WILL be water in the downstream channel due to the initial hydrograph. Man, this was giving me heartburn until I took a step back and thought things through. Thanks for the reply! Hope all is well.

    George:
    Thank you for the reply. The error is as follows:

    the SA 2D connection has a culvert lower than the cell it is connected to. Culvert! elev 488.9, Cell 3955 cell elev 452.64 between face points 4216 4217 for 2D area.

    How do I only make grid size in that location smaller? Can you provide direction or a video?

    Can you provide further direction on using ras mapper to make small terrain mods? Can you provide a video? THANK YOU.
