Undulating Surfaces modeling

How can we reproduce the undulations shown in the picture with existing components?
For example, undulations like a golf course. I would like to create a model where some parts are raised like this.

It doesn’t have to be mesh, but something like a place specific and undulating would be nice. I’m imagining something like this photo with the colors removed.
