Investigating the Capability of HEC-RAS Model for Tsunami Simulation

This study highlights the simulation of tsunami cases using HEC-RAS 6.1. The primary aim is to evaluate capability software in performing due its standalone computational framework (pre-processing, execution, and post-processing stages), making modeling process interactive. model accuracy was tested against some benchmark wave propagation, including analytical solutions, laboratory experiments, field measurements. results showed capable propagation. maximum elevation velocity magnitude were accurately computed for cases. Furthermore, sufficiently accurate obtained case, where properly computed. For cases, arrival time fluctuations water surface appropriately calculated. Root Mean Square Error values between numerical analytical/observed data relatively low below 30%, with Pearson Product Moment Correlation ranging from 52–99%. In addition eminence, a drawback found regarding graphical user interface (GUI) input boundary conditions. These findings will be beneficial coastal engineering community continuous development HEC-RAS.
