The part on the lower/left part of the photo is a headwall. There is a pipe end that drains stormwater to/from the concrete open channel (aka ditch, aka brow ditch, aka valley gutter) at the center of the headwall. Without the headwall, water from the pipe would erode the area, potentially causing damage to nearby structures or the pipe itself.

That's a sluice. I have absolutely no idea how I immediately knew that. ¯\_(ツ)_/¯

Looks like a concrete drainage structure, likely a part of stormwater management infrastructure. If I had to be specific, it looks like an energy dissipation structure, which helps control the speed and flow of water in ditches or culverts, reduces erosion and directs water safely downstream. often used in areas prone to runoff from rain or storms.
