As a resolution of the well-known hierarchy problem,like supersymmetry the model of extra spatialdimension(s) proposed by N.~Arkani-Hamed,S.~Dimopoulos and G.~Dvali(ADD) in 1998, and byL.~Randall and R.~Sundrum(RS) in 1999, have generatedconsiderable enthusiasm among the physics community. In this thesis, we have made a phenomenologicalstudy of both of these models. After a briefintroduction of the ADD model and the RS modelin chapter 1 and chapter 2 and a brief review of theexisting phenomenlogical studies in chapter 3, wehave derived the order $kappa^2$ Feynman rules inthe context of ADD model. In chapter 5, we haveinvestigated theeffect of gravity in the DIS (i.e. the process $e^+ +p rightarrow e^+ X$) and compare our result withthat at HERA to constrain the parameters of the RSmodel. In chapter 6 and chapter 7, we haveinvestigated several phenomenologicalconsequences of the radion (which appears naturallyin the RS model in order to stabilize thesize of the fifth spatial...
