accumulation issue

Thanks @rogerzzl, my guess is that if you are using D8, the flats did not resolve properly. Try the fix listed here by using a smaller epsilon value: #224 (comment)

I tried to use small epsilon value like resolve_flats(flooded_dem, eps=1e-7), but the acc result is still the same as the previous output

oops, I tried to look back the codes in sgrid.py, the param max_iter might cause this issue, so once I tentatively added resolve_flats(flooded_dem,eps=1e-7, max_iter=5000), the right result is there!!

Thank you Dr. Matthew Bartos for your useful suggestions and efforts with the awesome tool Pysheds, I'll close this issue then.

All the best!
