We study the determination of neutrino mass hierarchy, through neutrino experiments within the next ten years. The T2K neutrino oscillation experiment will start in 2009. In the experiment the high intensity νμ beam from JHF is directed to Super-Kamiokande (SK) detector 295 km away. The NOνA (off axies neutrino oscillation) experiment is being planned, with the νμ beam from Fermi-Lab directed to a site 610km away, which is 0,7,14 milliradian off-axies. Both the above experiments will measure νμ→νₑ oscillation probability. The double-CHOOZ experiment under construction detects νₑs emitted by nuclear reactors both through a near detector (150m) and a far detector (1.05 Km) and measure νₑ→νₑ survival probability. In this paper, we outline a procedure to determine the sign of Δ₃₁ from the simulated data of the above experiments.
