Occam’s razor is the preference for simple explanations over excessively complex ones. As obvious as this seems, there is resistance to trusting an explanation as simple as a recession constant for modelling streamflow, despite the complexity of the catchments. I like this explanation for why the simplest linear behaviour is reliable based on dissipation of potential energy at the minimum possible rate. This is a valuable concept for hydrographers to grasp, particularly for estimating periods of winter streamflow under ice conditions when other methods of producing discharge data fail.
