A city has asked me to design a culvert to replace one that they say is in "bad shape". I look at the culvert and it is a cm arch culvert with concrete walls for footings and a concrete bottom. Its diameter is equivalent to 8' and is under a busy road, in a flowing stream. The problem seems to be, not the pipe, but severe erosion at the outlet. The stream has undermined the wing walls and there is a fall of about 4' from the pipe to the stream. There seems to be a better solution of fixing the outlet situation instead of replacing the culvert. Am I missing something? I don't want to tell the city that we can just fix the outlet situation and they tell me why it would need replacing, thus I look like the idiot!

Lidar has been around for quite some time, but to date, it’s been custom—and expensive. Right now, there isn’t a clear-cut solution that’s suitable for all applications, such as lidar in autonomous vehicles. As they explore options, optical and mechanical engineers are forced to make choices and tradeoffs during the design process. Download Now
