In the work for the passive impurity transfer model, the construction of an optimal measurement plan for the implementation of a variational algorithm for identifying the power of pollution sources is considered. The Jacobi information matrix is constructed using solutions to a series of related problems. It is known that measurements of the concentration field, which are performed at the points of maximum values, lead to increased conditionality of the problem being solved and faster convergence of the iterative process. The algorithm for constructing the Fischer information matrix is presented for the case of a three-dimensional model of passive impurity transport in the Sea of Azov. The effect of an instantaneous and permanent point source of pollution is considered. The results can be used to solve various environmental problems in studying the effects of anthropogenic pollution sources in the waters of the Azov and Black Seas.
