Mathematical modeling of Russian northern coastal waters in the shallow water approximation

Abstract

Abstract In this paper, the authors present a model for computing a coastal waters flow in the shallow seas. The software implementation of the model consists in coupling the global software and the local hydrodynamic computations. The authors describe the use of the joint two computational packages: the global model for the ocean dynamics NEMO (Nucleus for European Modelling of the Ocean) which provides the initial and boundary conditions and the code WRF (Weather Research and Forecasting) for predicting meteorological conditions is used to calculate the wind loads. A hydrodynamic model based on the shallow water (SW) approximation is used to compute the coastal waters flow within a local domain, typically, 1000 km in size. The software implementation of the algorithm is based on regularized SW equations. As an example, the authors have computed the flow of the coastal waters in the vicinity of the Kara Strait. The study carried out demonstrate that all three algorithms successfully combined in the framework of the local computation and give the consistent results.
