I have a generated raster map containing different flood levels. Is there a grass script to determine the percentage of values in a raster map? I'm thinking of using r.mapcalc to solve this, but I'm not yet sure how to do it.

I think the function you need is r.stats

If your data is floating point, you will need to play around with the bucketing/quantization parameters such as nsteps
