Laboratory Testing Of Capillary Rise In Fine-Grained Sands And Silts, Rachel Salim
Laboratory Testing Of Capillary Rise In Fine-Grained Sands And Silts, Rachel Salim
Research and Creative Activities Poster Day
Data for the height of capillary rise in fine-grained sands, silts, and clays is inconclusive. The literature gives a wide range of values and equations. Once source (Applied Hydrogeology, 3rd ed., C.W. Fetter, p. 182) claimed that the height of capillary rise varies from 100 cm in fine-grained sand up to 750 cm in fine silt. We found these numbers unbelievable, and asked the late C.W. Fetter to put better numbers in his 4th ed. Instead, he deleted the table in the 4th ed. The equation which generated his numbers was used by Adamski et al. (2005)* to explain free …
