Can we modify elevation change due to Bridges and Dams in DEM with the help of ArcHydro?

I am doing Flood routing and Dam Breach modelling of the Case study of ancient times which is 1000 years old. 

I have a DEM of 30 m resolution SRTM and I want to modify its elevation so that the terrain can possibly resemble the old ancient terrain when there were no Bridges and Dams. 

Are there any possible way to do that with ArcHydro??
