The article is devoted to the development and research of methods for accelerating calculations and processing input data for mathematical modeling of hydrodynamic processes in reservoirs with complex bottom geometry. The mathematical model of hydrodynamics considers: microturbulent diffusion; the influence of salinity and temperature. To increase the speed of calculations, it is proposed to transfer part of the computational load to reconfigurable computing systems (RVS). The paper also proposes an algorithm for adding input data by analyzing the existing database of environmental data, which was successfully verified analytically. The practical significance of the work is that a hardware implementation of the IP core was proposed, which allows solving systems of linear algebraic equations that arise when sampling the model of hydrodynamics of the Caspian Sea. It is experimentally established that the resulting implementation is characterized by low power consumption and is capable of processing large-dimensional matrices. The prospects of using the proposed algorithm are determined.
