The Church has authority over the Sacraments, even to the extent of changing the form, permitting one form and not another. So Baptism can be permitted to occur with pouring, rather than immersion. However, Bl. Emmerich tells us that the Apostles, under Jesus' immediate supervision and instruction, baptized by pouring.
Also, the book The Teaching of the Church Fathers (Willis) has numerous quotes showing that the early Church Baptized by pouring as well as immersion.
