Abstract: A method, system and device for allocating total emission reduction of a water environmental pollution load are provided. The method includes: dividing a watershed based on terrain elevation information in watershed-related data to generate a plurality of watershed control units; with a watershed control unit as a basic unit, estimating a pollution load output in each watershed control unit by using an output coefficient method; acquiring GDP of each watershed control unit, and combined with the pollution load output, calculating relative environmental efficiency of each watershed control unit by using a data envelopment method; quantifying a contribution rate of a pollution load produced by each watershed control unit to a pollution load of a section of river entering the sea one by one based on a constructed watershed water environmental model; and formulating a pollutant emission reduction scheme according to the relative environmental efficiency and the contribution rate.

Abstract: A forecast operation method for lowering the reservoir flood limited water level considering forecast uncertainty is disclosed. The flood forecast feasibility of a reservoir controlled basin is analyzed, and the principle of maximum entropy is adopted to identify forecast error distribution; A framework of operation rules for lowering the flood limited water level at the flood rising stage is formulated by using an idea of pre-release, and the forecast operation framework is optimized to obtain forecast operation solution optimization point sets; All optimization point sets that achieve the upstream and downstream flood control safety in case of maximum forecast errors are screened out from the forecast operation solution optimization point sets; and finally, in comprehensive consideration of forecast errors and different preferences of decision makers, the optimal forecast operation solution points are evaluated by using a binary comparison method and a fuzzy optimization model.

Abstract: The present disclosure provides a reservoir scheduling method considering power generation, an ecological flow, and a surface water temperature. A plurality of optimization objectives of power generation, an ecological flow, and a surface water temperature of a reservoir are determined through analysis, and a multi-objective optimization model is constructed. A non-dominated sorting genetic algorithm III (NSGAII) algorithm is used to obtain an optimal value of a to-be-optimized parameter through solving. Scheduling control is performed on the reservoir based on the optimal value of the to-be-optimized parameter. The present disclosure quantifies a competitive and cooperative relationship among the power generation, the ecological flow, and the surface water temperature of the reservoir by using a multi-objective optimization method, and a reservoir scheduling rule that can balance the power generation, the ecological flow, and the surface water temperature of the reservoir is selected through analysis.

Abstract: The present disclosure refers to a method and a system of sudden water pollutant source detection by forward-inverse coupling, including: building an one-dimensional forward water quality simulation model of a river way according to acquired mechanical parameters and water quality parameters; according to the one-dimensional forward water quality simulation model of the river way, measuring and calculating each monitoring index by using an inverse optimization source-detection model; by constructing the one-dimensional forward water quality simulation model of the river way, using the inverse optimization source-detection model for measurement and calculation; and performing the Bayesian updating, in order to realize multi-information fusion. The present disclosure may reasonably control and use different observation information, and combine the redundancy or complementarity of multi-sourced information in space or in time to obtain consistent interpretation of the measured object, thus overcoming the uncertainty of the water environment, improving the accuracy of water pollutant source detection.
