The water cycle is governed by the thermodynamic laws. Therefore Thermodynamics and more specifically Exergoecology, that is the application of the exergy analysis in the evaluation of natural fluxes and resources on Earth, could help to build a solid cost structure based strictly on Physics and...

The Georgescu-Roegen’s statements about the connexion between the Economy and the Thermodynamics, together with the Eco-integrator approach introduced by Naredo and its relation with the water cost definitions given in the European Water Framework Directive (WFD), are the outline backgrounds...
