南水北调中线渠道控制计算模型

南水北调中线总干渠线路长、供水范围广，沿线分光口门多，做好总干渠的运行控制十人刀要。闸前常水位和控制容量方式是中线最合适的控制方式。根据中线工程总体设计成果，分别为这两种运行方式研制渠道控制计算模型。由用水户的分水流量和计算模型可以出渠道节制闸的最终闸门开度，供调度使用。

Computation model for channel flow control of the Middle Route Project for S-to-N Water Transfer

The main trunk channel of the Middle Route Project for South-to-North Water Transfer has a long route,a vast water supply district and numerous water-diverting outlets along the channel,so it is necessary to well operate and control the main trunk channel.Maintaining constant water levels at sluices and controlling water storage capacities of all channel reaches are the most suitable control modes.Based on the general design results,two computation models for controlling the channel flow by means of maintaining constant water levels at sluices and controlling water storage capacities of channel reaches are developed.The gate opening of a regulating sluice can be determined by the computation model and according to diversion discharges of water users.The computation model can be used for the water supply regulation.
