Mathematical Modeling and Visualization of Large-Scale Flooding in the Flood Plain of Naryn River Using OpenFOAM

This paper presents the results of mathematical modeling, forecasting and three-dimensional visualization of large-scale hydrodynamic flows in areas with complex topographic terrain within the framework of the open application package OpenFOAM7 and the scientific visualization package Paraview5.6. The basis of three-dimensional non-stationary modeling is the Reynolds-averaged Navier-Stokes equations. New hydrodynamic and computer models are proposed to analyze the dynamics of breakout waves progress in areas with complex terrain. The effectiveness of the modeling technology used was illustrated by the example of a possible flooding in the flood plain of Naryn River, Kyrgyzstan. #CSOC1120.
