The prepositional phrase is "by the river" and the object of the preposition is the river.
The chronology described in the excerpt would be:
Idian Ocean Tsunami (2004) - Founding of World Bicycle Relief (2005) - 24,000 new bicycles for a recovering Sri Lanka (2005-2006) - The WBR moves to Africa to work with at-risk groups (2006).
Chronological arrangement of the facts in a piece of writing like the one you're presented with, serves as a way of organizing the unfolding of a process in a linear fashion. That way, the cause-and-effect relationship of each event can be more clearly understood. In this case, we get a really good picture of why the WBR was created, what did it do in the beginning, and how their work evolved.
Hope this helps!
