Application of Surrogate Modeling in Stochastic Analysis of an Ogee Spillway Structure

International Journal of Mechanical System Dynamics, Volume 5, Issue 2, Page 290-311, June 2025.
ABSTRACT This study investigates the hydraulic performance of an Ogee spillway under varying flow rate conditions, gate opening heights, and spillway widths. Numerical simulations using Flow‐3D, incorporating the (k‐ε) turbulence model and Large Eddy Simulation (LES), were employed alongside surrogate models using MATLAB codes and LP‐TAU to predict ...

Evidence of strong long-period ground motions of engineering importance for Nankai Trough plate boundary earthquakes: comparison of ground motions of two moderate-magnitude earthquakes

Earth, Planets and Space, 2018
We analyzed strong-motion and broadband recordings of two moderate-magnitude earthquakes that occurred in the Nankai Trough. The first event was the 2004 Mw 6.5 southeast off-Kii peninsula earthquake, an aftershock event inside the Philippine Sea Plate ...

Taxonomy of κ: A review of definitions and estimation approaches targeted to applications [PDF]

, 2014
In a way perhaps not dissimilar to stress drop (Atkinson and Beresnev, 1997), the high-frequency attenuation parameter κ (kappa), introduced by Anderson and Hough (1984), is one of the most used yet least understood or agreed-upon parameters in ...

Probabilistic earthquake-tsunami multi-hazard analysis:application to the Tohoku region, Japan [PDF]

, 2016
This study develops a novel simulation-based procedure for the estimation of the likelihood that seismic intensity (in terms of spectral acceleration) and tsunami inundation (in terms of wave height), at a particular location, will exceed given hazard ...

Support Vector Machines to Propose a Ground Motion Prediction Equation for the Particular Case of the Bojorquez Intensity Measure I_Np

AI
This study proposes the first ground motion prediction equation (GMPE) for the parameter INp, an intensity measure based on the spectral shape. A Machine Learning Algorithm based on Support Vector Machines (SVMs) was employed due to its robustness ...

Earthquake Stress Drops From Dynamic Rupture Simulations Constrained by Observed Ground Motions

Geophysical Research Letters, 2020
Stress drop characterizing dynamics of earthquake rupture propagation has various definitions and measures with a yet unclear mutual relationship. We aim to reconcile this discrepancy by analyzing synthetic dynamic rupture models generated by random ...
