Popis: |
Three kinds of underground aquifers are observed in Guangzhou with universal shallow water level. The water content is abundant in the strata along the coastal area of Pearl River and Liuxi River, in Guang-hua alluvial plain, carbonates rock karst area and fault fracture zones. The specific yield of the carbonate rock fissure cavern and paleo-channels reaches 1539–2131 m3/d and 1054–4680 m3/d, respectively. The water yield property gradually decreases with the increasing distance from the rivers. On the other hand, the underground water exploitation and running water system have negligible effects on the underground water level, and the construction in the underground space also has no long-term influences on the underground water level due to the abundant recharge resources. It is concluded that the determination of anti-floating water level has strong regional characteristics since the distribution of underground water level is similar to the topography. Some practical advices for determination of the anti-floating water level in Guangzhou are proposed. |
