Modeling of water use and river basin environmental rehabilitation

The ecosystem model of surface water quality in the river basin was formalized on the basis of the theory of neural networks. The neural network is trained based on the observation data. Upon that the methods of environmental assessment and suitability of water for irrigation as well as for drinking needs can be used for the neural networking. The developed ecosystem model enables to improve significantly the water use and decision making for the purposes of the environmental rehabilitation of the river basin compared to the existing approaches. As an example we considered the Inhulets River. The ecosystem assessment of water quality for irrigation needs along the river bed was made. Using the neural network model a system model for the complex control of the river bed flushing was developed. The model performs a feedback based on the observations data at the water intake point. It enables to evaluate and select better scenarios compared to the existing operational procedure of flushing.
