Dynamically changing bottom relief modeling based on spatially inhomogeneous 3D mathematical model of wave hydrodynamics

The article is devoted to the construction and adaptation to natural and climatic conditions and geographical features of precision mathematical models of hydrodynamics of wave processes and relief formation. The incompleteness of data is characteristic of the new tasks considered in the article, the solution of this problem is carried out by involving remote sensing and cadastral survey data. It is essential to include in this complex algorithm for constructing raster models of dynamically changing bottom relief based on known cadastral survey data and remote sensing data. The software package described in this paper makes it possible to reduce the forecast time of hydrophysics processes, including dangerous and catastrophic phenomena. On the basis of the developed software package, prognostic calculations of the processes of coastal erosion and changes in the bottom relief were performed. Modeling of the state of a water body takes into account the characteristic features of natural processes, among which it is worth noting the spatial and temporal variability of relief formation
