The interbasin water transfer is a remedy to mitigate the negative issues of water shortage in arid and semi-arid regions. In  a water transfer project  the receiving basin always  benefits while, the sending basin may suffer. In this study, the project of interbasin water transfer from Dez water resources system in south-west of Iran to the central part of the contrary is  investigated during...

  Abstract Given the importance of water resources in sustainable development, it is necessary to investigate the direct and indirect impacts of inter-basin water transfer projects. The present research analyzed the status of the water resources in the south of Kerman province and the challenges of inter-basin water transfer that will result from transferring water from the upstream Halilroo...

The interbasin water transfer project is an alternative to balance the nonuniform temporal and spatial distribution of water resources and water demands, especially in arid and semi arid regions. A water transfer project can be executed if it is environmentally and economically justified. In this study, the feasibility of two interbasin water transfer projects from Karoon River in the western p...
