A scientific evaluation of groundwater resources in Asia can be secured using water balance method and runoff modulus method through water circulating analysis and feature study of groundwater system on the basis of groundwater system division of Asia. With natural recharge(runoff) modulus(10~4m^3/km^2·a), the total amount of water resources and those available for exploitation of primary groundwater system can be evaluated-continuous aquifers in plains and basins contain 242.465× 10~9 m^3/a of water, 169.725× 10~9 m^3/a of which is recoverable; discrete aquifers contain 186.695× 10~9 m^3/a, 130.686× 10~9 m^3/a of which is available for exploitation; other scattered aquifers contain 38.614× 10~9 m^3/a, 27.029× 10~9 m^3/a of which could be exploited. In total, there is 467.774× 10~9 m^3/a of groundwater with 327.440× 10~9 m^3/a recoverable. The groundwater map of Asia is compiled according to groundwater system division, evaluation of the total amount and aquifer types to reflect the macro features of groundwater resources in Asia, laying a scientific foundation for exploitation and management of water resources here and for avoiding disputes over groundwater resources and environment among Asian countries.展开更多

This forms part of the work of the groundwater series map of Asia, which is compiled according to groundwater system division and evaluation of the total amount and types of aquifer, reflecting the large-scale features of groundwater resources in Asia. Systematic profiling of groundwater in this way provides a scientific basis for groundwater exploitation planning and management in Asia, and avoiding disputes over groundwater resources and the environment among Asian countries.展开更多
