Validating Geoclaw For Simulating Teton Dam Failure By Comparison With Hec-Ras Results And Historical Observations, Hannah R. Spero

Geosciences Undergraduate Theses

The combination of dams degrading with age and other factors like climate change, technical errors, and human errors lead to dams breaching and failing worldwide. In the United States, over 40,000 dams pose a threat to downstream inhabited areas and constitute a widespread hazard if they were to breach. Therefore, it is critical to accurately predict the resultant floods’ downstream flow behavior to create a more resilient community. By improving research, we can concurrently develop and improve mitigation strategies for downstream communities. This study benchmarks the GeoClaw numerical modeling software with the well-documented 1976 Teton Dam failure. A vital tool …
