4.4 Case 4: Spatially Uniform to Top-heavy
In this final case, we the model the catchment response to a change in
rainfall pattern from spatially uniform 1.5 m/yr to a gradient that
increases upstream from 0.25 to 2.25 m/yr, which also results in a
complex transient response. Mean rainfall decreases by 33% and fluvial
relief also decreases by 10% (Figure 3; Movie S4), which contrasts with
the 22% increase in fluvial relief expected for a spatially uniform
decrease in rainfall of the same magnitude.
