The appositive is usually a group of words related to a noun, usually a subject, and describes it in more detail. The appositive here is a river that flows through Egypt. Another way of easily spotting an appositive is by looking for commas - if it is separated from the rest of the sentence by commas, it is likely to be an appositive.
