In China water resources are unevenly distributed.In general, water resources are abundant in the south but deficient in the north.With the increase of population and rapid economic development, the problem of water shortage in the north is getting more and more serious.One solution is to divert water from one drainage area to another, also known as the South-to-North Water Diversion Project.There are three routes.The eastern route will transfer water from the lower reaches of the Yangtze River to north along the Beijing-Hangzhou Grand Canal and through a tunnel under the Yellow River, from where it can flow downhill to reservoirs near Tianjin.The central route is from Danjiangkou Reservoir on the Han river, a branch of the Yangtze River, to Beijing.The western route, also called the Big Western Line, aims at diverting water from the headwaters of the Yangtze River into the headwaters of the Yellow River.
