Best Way to Create Slider for Topo Contours?

Hello. I’m a newbie and landscape architecture student. My project involves altering topographic elements to modify sound. I currently have all of the contours as curves in a Rhino file. What would be the best elements to use which would allow specific areas of the topography to be raised on a slider? I’d like to experiment with different heights of topo. Thank you so much for your help.
