    Create another raster from polygons with an elevation set to something reasonable and merge it with this one. I’m not a GIS expert though. You might try https://gis.stackexchange.com for answers.

    You would need to find another terrain source to merge in HEC-RAS. If you use GIS, you could have it interpolate over the missing area or merge it with other terrain.
