Chapter 33: Stream Erosion

The Edmonton River Valley (Larchlands)


Much can be revealed by analysing drainage patterns of a stream, specifically about the underlying geology. As an erosional force, the efficiency of the drainage system is immediately related to the drainage density, and consequently the strength of the drainage density is then directly related to the system’s erosional efficiency. Should the stream seen behind me in this photograph be analysed, its patterns would make it possible to discover the stream’s hidden geology.
