Costs and Benefits of Hard Engineering: Dams and Channel Modification Case Study, Slides of Engineering

The concept of hard engineering, focusing on the costs and benefits associated with the construction of dams, reservoirs, channel straightening, embankments, and flood relief channels. Through real-world examples, such as the Hoover Dam and the 3-Gorges Dam, students will gain an understanding of the debates surrounding the implementation of hard engineering projects.

What you will learn

  • What are the benefits of constructing dams and reservoirs?
  • What is hard engineering and how does it prevent or control the flow of rivers?
  • What are the primary costs associated with hard engineering projects?
  • How does channel straightening impact the environment and local communities?
  • What role does management play in the implementation of hard engineering projects?
