This research introduces the idea that the international legal protection of natural resources of cultural value can be developed in a way that combines International Water Law with the rules of International Law in relation to cultural heritage through an applied study on the case of the Nile River (as a natural resource). Accordingly, the research raises several questions: Does the cultural value of the Nile justify the protection of international law within the framework of the legal rules applicable to cultural heritage? If it has been, theoretically, demonstrated that the Nile has a cultural value under international law relating to cultural heritage, can this be translated in practice, and can the results be generalized to all natural resources of cultural value?
