This paper covers the principles of conjunctive use of groundwater and surface water
Conjunctive use of water is the coordinated management of both surface water and groundwater for water supply. This Thematic Paper describes the principles of conjunctive use of groundwater and surface water and highlights some of the misconceptions related to conjunctive use, which can result in unsustainable use of water resources. Conjunctive use of surface and groundwater consists of harmoniously combining the use of both sources of water in order to minimize the undesirable physical, environmental and economical effects of each solution and to optimize the water demand/supply balance.
The paper provides examples from international as well as from Chinese experience, and concepts are elaborated on using a variety of illustrations.
The Thematic Paper covers the following topics:
- rationale for using conjunctive use
- surface water schemes
- roundwater schemes
- conjunctive use schemes
- managing conjunctive use schemes
- establishment of scheme
- overview of risk
- policy and issues
- both international and Chinese examples
