长湖水电厂流域产汇流模型的研究

产汇流模型是根据TANK模型,经引入优化原理和改进模型结构并结合长湖水电厂流域自然条件特点而研制的水文模型.模型采用直列式三级串联和两列并联结构;参数直接由实测雨洪资料分析、综合求出,客观地描述了产汇流过程和流域暴雨洪水特点。该模型还具有优化计算和对预报值作实时跟踪校正的功能。

A Study on Runoff-Producing and Converging Model in the Upstream Watershed of Changhu Hydroeletric Station

In this paper a runoff-producing and converging model proposed is a hydrologic one in which the optimal theory is introduced and the model structure is improved by combining with the physical feature of the watershed of Changhu Hydroeletric Station on the basis of the TANK model. Because the model structure adopts a series of three classes and two parallel ranks and the parameters of the model are determined by analyzing and synthesizing the storm and flood obserdation data, therefore, the model can descride objectively the runoff- producing and coverging processes and the characteristics associated storm and flood with the physical features of the watershed; besibes, it has the functions of optimizingcalculation as wella3 real-time update predction, ensuring higher precision for the model.
