Short summary
This paper simulates river basin water markets under two licensing regimes: fixed volumetric allowances and scalable licensing with dynamic environmental minimum flow requirements. The model is applied to the Great Ouse River basin in eastern England, with each water user from four main sectors represented individually. The results suggest that the scalable licensing system is more effective in protecting environmental flows, at the opportunity cost of 10-15% of economic benefits to water users.
