Characteristics of groundwater and urban emergency water sources optimazation in Luoyang, China
-
Abstract: The construction of emergency water sources is the material basis for ensuring urban water safety, and it is also an inherent requirement for maintaining social stability and development. The hydrogeological characteristics of groundwater in Luoyang City from the aspects of the division of groundwater aquifer groups, water yield property and groundwater dynamics were described in this paper. Two emergency water sources were selected on basis of comprehensively considering groundwater resources and ecological environmental effects, groundwater quality and exploitation technology, etc. Then it further analysed the aquifer types, water yield properties and groundwater recharge, runoff and discharge conditions of the two emergency water sources, and evaluate the groundwater resources quantity of the water sources. The results are that the shallow underground aquifer in Luoyang City is thick, coarse, and stable in lithology and thickness. The two water sources enjoy good exploitation potential and can be used as backup water sources to supply water in the event of a water source crisis.
