Implementation of hopeful of Yellow River water supply is accurate and online me
From;  Author:Stand originally

Understood from bureau of water supply of committee of Yellow River irrigation works recently, online and the accurate, real time that leaves yellow water supply to come true, metric, committee of Yellow River irrigation works already approved water supply of Yellow River number to run a system pilot project implements plan, at present branch of Yellow River water supply is clutching carry out " digital water supply " , pilot undertaking in insecurity.

As we have learned, downstream number water supply manages construction Yellow River the system is to result from pair of Yellow River water supply " two moisture are offerred, two cost are divided plan " requirement. "Two water " those who point to is agriculture uses water with water and blame agriculture, "Cent is offerred " it is to point to in same in bringing Huang Qu to fasten, agriculture uses moisture period of time to be supplied centrally alone with water and blame agriculture; "Two cost are divided plan " it is to point to the contemporary and metric method that uses advanced, science, limit agriculture well and truly, clearly to use the dividing line of water with water and blame agriculture, execute accurate and apart, metric, distinction collects fees. But, in bringing tradition of yellow water supply to manage, agriculture and blame agriculture were not distinguished all the time with water, blame agriculture uses water not alone and metric, use water by cheap agriculture however meterage, abet on certain level the happening that is not agriculture to waste a phenomenon with water. Add the Yellow River to bring yellow water supply to still use conventional artificial observation means at present downstream, automation degree low, error is big.

"Annual bureau of each water supply supplied how many water after all, blame agriculture used how many water after all, it is a muddleheaded Zhang all the time. Below market economy condition, the Yellow River water that is in short supply increasingly originally serves as commodity, must undertake accurate and metric, ability protects water natural resources better, protect the interest of unit of Yellow River water supply. " Wang Xiwen of engineer of bureau of water supply of Yellow River committee was participated in " digital water supply " of the project carry out. He thinks, undertake gage to Yellow River water supply, those who be helpful for Yellow River water is managing and efficient use, build harmonious water supply new order.

According to Introduction Wang Xiwen, come for years, in Yellow River water supply metric respect, adopt for a long time come back artificially oar type is metric establishment undertakes actual measurement. Below normal flow condition, by hydrology the personnel that monitor was mixed at 8 o'clock every morning undertook actual measurement respectively at 4 o'clock afternoon, the discharge that day regards as the value after the data that gets two is average. Because measure the effect that suffers a variety of elements such as spatio-temporal, climate artificially, and cannot realize real time online monitor, the accuracy of metric respect is hard to hold, offer, the contradictory controversy that arouses metric respect easily with both sides.
