When Hurricane Harvey hit Houston in August of 2017, the Lumpkin Road detention pond flooded and receded multiple times and performed exactly as engineered. Some areas of Houston received 40 inches (1 meter) of rain in less than 48 hours, but there are no signs of movement or distress with the walls.

Erosion Control magazine has an interesting article on MSE Walls. I think the tie-in of MSE Walls with erosion control is a little questionable (they did mention wall drainage a few times), but the article highlights several interesting projects, particularly the Seattle-Tacoma Airport or Sea-Tac Third Runway Project retaining walls. The West wall for that project is the tallest MSE Wall in North America, 130-ft at its highest point. More after the break. (Photo by Sea-Tac Airport)
