A Flash Flood Numerical Modeling and Forecasting Tool in Mountainous Small Catchments Based on a 2‐D Hydrodynamic Model

open access: yesEarth and Space Science, Volume 12, Issue 7, July 2025.
Abstract The forecasting and early warning of flash floods in mountainous areas are extremely challenging. Here, we establish an integrated model of Baseflow‐Rainfall‐Interception‐Flood (BRIF) to support efficient numerical modeling and potential forecasting of flash flood in future.

A spectral FC solver for the compressible Navier–Stokes equations in general domains I: Explicit time-stepping [PDF]

open access: possibleJournal of Computational Physics, 2011
We present a Fourier continuation (FC) algorithm for the solution of the fully nonlinear compressible Navier-Stokes equations in general spatial domains. The new scheme is based on the recently introduced accelerated FC method, which enables use of highly accurate Fourier expansions as the main building block of general-domain PDE solvers.

Efficient representation of exact coherent states of the Navier–Stokes equations using resolvent analysis

Fluid Dynamics Research, 2019
A resolvent analysis of exact coherent states (ECS) of the Navier–Stokes equations (NSE) in a low Reynolds number channel is performed. The resolvent framework recasts the NSE into an input/output form in which the nonlinear term is treated as an internal forcing that drives the linear dynamics of the system.
