Conceptual Metaphor
NATURE CLEANSING/CARVING THE LAND (The landscape is a surface being cleaned or sculpted by rain).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'ливневая канализация' (storm drain). The correct conceptual translations are 'смыв (почвы) дождём' or 'дождевой смыв'.
Common Mistakes
- Using it as a verb (to rainwash) is non-standard. Using it in non-scientific contexts where 'erosion' or 'runoff' would be clearer.

FAQ
Frequently Asked Questions
No, it is a very low-frequency technical term used almost exclusively in geology and physical geography.
No, it is not standard. Use 'washed away by rain' or 'eroded by rainfall' instead.
Rainwash is a specific *type* of erosion caused directly by the impact and flow of rainwater, as opposed to erosion by wind, rivers, or glaciers.
In non-technical contexts, 'soil wash' or simply 'erosion from rain' are more understandable alternatives.
