I garden a little like this in that I have permanent paths. The beds are raised just by cultivation, burying "compostables" in them, and keeping the paths cleared. I level the top of my beds so that they are not rounded. Since the compostables decompose thru the season, the ground settles in the middle of the beds even further.
If water was being poured on the beds, that "waffling" technique would be a good idea to hold the water around individual plants or groups of plants. With the sprinklers and level ground, water doesn't move around to quite that extent in my garden, however.
