Flood risk in past and future: A case study for the Pawtuxet River's record-breaking March 2010 flood event. [PDF]
J Flood Risk Manag, 2020 Abstract In March 2010, a sequence of three major rainfall events in New England (United States) led to a record‐breaking flooding event in the Pawtuxet River Watershed with a peak flow discharge of about 500‐year return period. After development of hydrological and hydraulic models, a number of factors that played important roles in the impact of this

Application of Surrogate Modeling in Stochastic Analysis of an Ogee Spillway Structure
International Journal of Mechanical System DynamicsABSTRACT 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 ...
