Large diameter tunnels have been successfully deployed for flood mitigation and water conveyance in North America. More and more owners are taking a step back when it comes to large water infrastructure projects that disrupt quality of life by causing surface interruptions, and evaluating tunnels as an alternative. The costs and risks associated with tunneling has decreased over time with the development of specialized and highly effective construction equipment suitable for most ground conditions. Because tunnels are deep underground, the surface space required for construction is limited and hence the disruption to the public. Tunnels are designed for 100-150 year service life, but are known to well outperform the design life with routine inspection and maintenance. We will present case studies where successful implementation of tunnel projects has led to long term flood mitigation success in a sustainable manner. The webinar will provide an overview of the flood control tunnels, how they work and provide case studies of such tunnels in Charleston, SC and Dallas, TX.
