In a nutshell

The contourmerge plugin helps you to align the contours of areas in JOSM.

Here's a typical example: a lake with a detailled shoreline and a forest.

The contour of the forest should be aligned with the lakes shoreline.

Select the contourmege map mode in the toolbar for map modes and perform the steps below.

Step 1 - Select the "cut-nodes"

• Select the part of the contour you want to merge, in both the areas for the lake and the forest. Left-Click on the respective nodes to mark them as selected.

Step 2 - Drag the source contour

• Drag the source contour between two "cut-nodes"

• When you drag it over a possible target contour, the source contour is aligned with the target contour.

Step 3 - Align the contours

• Drop the source contour. The contours of the lake and the forest are merged.

If the merge doesn't happen as expected, reversing one of the ways helps.
