  Phenomenological aspects of flavor changing processes are considered in the
context of the supergravity model.Various flavor changing neutral current
processes in B and K decays are calculated in such models. For lepton flavor
violating processes the $\mu^+ \to e \gamma$ branching ratio and the T odd
triple vector correlation for the $\mu^+ \to e^+ e^+ e^-$ process are
investigated in the SU(5) SUSY GUT. Possibility to find SUSY effects through
these Flavor changing processes in future experiments are also discussed.
