Abstract:

Applications of water environment models are greatly limited by complex internal structure of the model and timeconsuming calculations, significant computation burdens arise during the process of parameter calibration, multi-scenario analysis, and decision-making optimization.How to integrate water environment model and big data technology, deeply explore the potential of model application and give full play to its application value is a research hotspot.The bottlenecks faced by the water environment model in the process of practical application were summarized, and the potential of big data technology in solving these problems was analyzed.Based on the existing big data technology, a framework for the integration of water environment model and big data technology was proposed to solve the problem of large-scale calculation, large-scale storage and application analysis of water environment model.The problems faced in the integration of model and big data technologies were described, and specific technical ways of implementation were proposed.A case study for calibration of SWAT model was used to demonstrate feasibility of the proposed framework.Finally, the future research direction of water environment modeling in the context of big data was discussed, and the conclusion was pointed out that the research on surrogate modeling of complex water environment model and on water environment simulation and optimization framework is the future development trend.
