The neutrino oscillation parameters and mass hierarchy are nowadays under considerable investigation and a motivation for the conception of new neutrino detectors. This seminar will present three experiments under construction that will be able to determine the mass hierarchy exploring different oscillation parameters: KM3NeT-ORCA, a Mediterranean deep-sea neutrino detector will explore oscillation of atmospheric muon neutrinos; JUNO, an underground scintillator neutrino detector, will explore the oscillation of electron anti-neutrino from medium baseline reactors; in case of Majorana neutrino, SuperNEMO will be sensitive to the effective neutrino mass by measuring the neutrinoless double beta decay, and consequently to the mass hierarchy.

After a presentation of these three experiments the measurement methods and expected results will be discussed, highlighting their complementary for the determination of neutrino mass hierarchy.
