1928Geogr. Rev. XVIII. 590 The less weathered clays..show opposite properties, with respect to erosivity, to the tropic-like or highly-weathered clays. 1961N. W. Hudson in Proc. & Trans. Rhodesia Sci. Assoc. XLIX. 16 We may divide our study into two parts, firstly the ability of the rain to cause erosion (and this we call the erosivity of rain) and secondly the susceptibility of the soil to erosion (called the erodibility of the soil). 1985Earth Surface Processes & Landforms X. 70 The influence of drop shape on erosivity was tested by relating detachment and transport of sand particles with erosivity parameters. |
