Create a cube, subdivide it (smooth), cut it in half, select its middle edge, bevel it, select the bottom half, drag it down.

The direction of the curve matters; you may have to switch that.

, and scaled a bit
on z

Afterward, from the look of your reference you could probably use an array modifier to handle the copies.
