MODELING OF OPERATIONAL CONTROL OF THE OXYGEN REGIME OF THE AQUATIC ECOSYSTEM IN THE CONDITIONS OF THE DNIEPER BASIN

The article investigates the adequacy of the mathematical model of oxygen regime prediction in the Dnieper basin, based on the classic Streiter-Phelps
model. Retrospective analysis of the Dnieper oxygen parameters with further verification of the Streeter- Phelps model adequacy for the Dnieper basin conditions was used. The mathematical model of the dynamics of the integral indices of the ecological state of the reservoir (the Streeter-Phelps model) has been improved by supplementing the corrective coefficients, which allows predicting with sufficient accuracy the change of the Dnieper ecological state.
