Abstract: | In order to prevent the catastrophic events such as extreme drought, continuous drought and source-water quality pollution, 15 groundwater emergency water sources are to be selected in 11 important cities in Hebei, and the evaluation of allowable emergency exploitation quantity is 180.19×104 m3/d. Under the current conditions, the water supply quantity of emergency water sources and the total emergency water supply quantity will meet the emergency water demand with the guarantee rate of 65.79% to 377.78% and 90.35% to 270.51% respectively. By 2020, the water supply quantity of emergency water source places and the total emergency water supply quantity will meet the emergency water demand with the guarantee rate of 22.08% to 74.49% and 82.65% to 144.08% in the benefited areas of South-to-North water diversion (SNWDP); and for non-SNWDP areas, the guarantee rate will be 74.64% to 337.78% and 74.64% to 377.78%. |
