That's a bit complicated:

You go to the %Appdata/Roaming/.minecraft/saves/ /MiddleEarth/region folder.

There you find a lot of files called e.g. r.2.-4.mca or so. These are the world region files as far as they are already generated. In these is stored which block is on which position. A chunk consists of 16x16x256 blocks. It is only 16 blocks long and wide, but 256 heigh. I don't know how many chunks a region holds. Let's asume also 16x16 chunks. So a region would hold 256x256 blocks.

The numbers behind the "r" are the x and z coordinates. So the r.2.-4.mca holds the blocks from x = 2*256 = 512 to x = 3*256 = 768 and y = -4*256 = -1024 to y = -3*256 = -768 (asuming that I am right with the 16 x 16 chunks per region).

When you remove this file (make a backup in advance!) and reenter this region, the landscape will be generated there again - with roads, perhaps different heights or whatever Mevans has updated in the mod. When you have something built in that region, this will disappear. Buildings at the edge of the region will be cut in half. Sometimes this looks quite weird. Therefore backup your world before deleting a single file!
