These basic allocation schemes have evolved gradually toward more complex
systems that allow for the coexistence of elements from different doctrines,depending on factors such as flow discharge, type of water source, historic

the public goods involved, and the complexity of the interrelations in these
systems, have all led to greater State involvement and influence in water
management. The current widely accepted view is that water resources – both

that the State should be responsible for controlling, regulating and allocating
