Abstract

The invention relates to a hydrological model parallel calibration method and system based on graph calculation, and the method comprises the steps: decomposing a hydrological model into sub-basin models, converting a model calibration process into directed graph expression, and achieving the model calibration parallel simulation in a Spark cluster through employing a Pregel algorithm. The hydrological parallelism calibration method can quickly realize hydrological parallel calibration.

Description

technical field [0001] The invention relates to the technical field of hydrological calibration, in particular to a method and system for parallel calibration of hydrological models based on graph calculation. Background technique [0002] The hydrological model is the abstraction and generalization of the complex hydrological phenomena in nature in the computer. It is an effective means to understand the process and mechanism of the complex hydrological cycle, and it is also a powerful tool to solve many practical hydrological problems. Driven by the development of remote sensing technology and other sensor technologies, the data used to construct hydrological models is becoming more and more abundant, and the research on hydrological models is gradually developing into the era of big data. Under the effect of big data, the spatio-temporal scope of hydrological modeling continues to expand and the scale becomes finer and finer, and the improvement of human understanding of ...
