Modeling dam and levee breach and the impact of hydraulic structures on channel routing and flood inundation

Objective:

Develop a state-of-the-art hydraulic model describing breach evolution in earth dams and levees

Abstract:

Flood prediction is a critical aspect of disaster management, necessitating a deep understanding
of complex phenomena such as dam and levee breaches. One-dimensional and two-
dimensional unsteady computer models are instrumental in simulating river and stream
dynamics, as well as the interaction with hydraulic structures. However, the unique challenges
posed by levee breaches, especially due to lateral flow, require tailored analysis. This project
embarks on a systematic journey, commencing with the development and rigorous validation of
detailed computer models for the temporal and spatial evolution of dam and levee breaches. A
particular focus is placed on breaches initiated by overtopping, given their substantial influence
on the flooding dynamics both upstream and downstream. The approach capitalizes on a vast
wealth of knowledge, combining insights from existing literature with data obtained from our
team's ongoing and prior laboratory experiments. The goal is to refine and validate the models
to ensure their robustness and accuracy. Furthermore, large-scale tests will provide a final layer
of verification before the models are employed in real-world scenarios. Upon the project's
completion, we anticipate having data-driven models for dam and levee breaches that can cater
to typical structural configurations. To maximize the utility of our research, we will disseminate
our findings through peer-reviewed publications, presentations at national and international
conferences, and engagement with college students and the public through outreach events. By
uniting computational and data-driven models, this endeavor seeks to enhance our ability to
predict and mitigate the devastating impact of flood events.
