Even though the watershed may cover a large area, what happens in one part of the watershed may have both direct and indirect effects on other portions. For example, installation of an irrigation diversion in the upper portion of the watershed may result in a reduction in the amount of water which moves through the channel further downstream. This could change the type of vegetation that can grow in riparian areas in lower portions of the watershed.

Another example: a timber harvest in the upper part of the watershed may result in more water flowing into the channel over a shorter period of time because less is being used by large, deep-rooted woody vegetation. The result could be higher overbank flooding in some years or increased lateral or vertical cutting because the increased volume of flow places additional pressure on streambanks and the channel bottom.
