As much as culverts and drainage structures have changed over the past 100 years, the next millennium should see even more rapid change and improvement. The materials, products, and construction techniques will result in more durable, better-performing structures. Design will become totally computer aided, with location and sizing based on satellite imaging and Global Position System data. This paper comments further on materials, installation, and the future outlook in culverts and drainage structures. |
