[RegCNET] Erasing topography....Help Please!

[Highland Boy]

Dear all

I am trying to study the effect of topogrphy on rainfall by using RegCM. For
this I want to run the model with  and without topography. But I have no
idea as to how I will erase the topogrphy. It is said that we have to reduce
the elevation to sea level to do it, but I don't know how....Please advise
and Help.

Thank you all in advance...
