Map view sketchSkecth showing subsidence pattern

Two map views of prototype basin. On left, the line of three transects (red, blue and green) are shown. Their position is measured as distance, in mm, to the right of the center line as seen facing downstream.

On right is same view, but shows approximate area where relative base level is always rising due to high subsidence rates, even during the slow absolute base-level fall.
