Key Points
- Spatially variable rainfall complicates steady state relationships
between mean rainfall and conventional topographic and erosion
metrics.
- Transient responses to changes in rainfall pattern differ from uniform
changes in rainfall, which affects how they may be detected.
- Rainfall gradients can obscure the sensitivity of fluvial erosion to
rainfall variations and impede quantification of climate sensitivity.
