Best thing to do would be to call the manufacturer to get their opinion. With it on the back you will have more erosion with water spilling over the top and falling down. That could could be fixed with mounting the riser on a concrete base and placing rock all around the base so that the water doesnt fall on to dirt.


If it was set up this way, I would think a disadvantage would be the amount of water flow. Instead of the typical situation where the pipe gets full from a rain event and the elevation drop helps increase the pull of water thru the pipe, in this scenario the water is having to push itself back up to the same level as the pond. Perhaps someone who knows real physics/water pressures will chime in on this thought to confirm or deny it.
