Very little research has been done on the capillary rise in soil for agriculture and geotechnical engineering. The capillary rate rise of water in fine granular soil is one of the major challenges for rising experiments in vertical tubes, as the time required for the water to reach the maximum height of capillary rise can vary from 100 to 400 days. The present research aimed to validate a correlation curve for the capillary rise of a silt-clay soil of the Guabirotuba Geological Formation (Paraná, Brazil) as a function of the time of water rise. The control variables of the study were: compaction, water content, porosity, hydraulic conductivity, soil column height, and rate of capillary rise. Results were gathered by comparing the behavior of capillary rise using the analytical solutions developed by Terzaghi and Lu and Likos. On analysis of the results, it was concluded that the equation proposed by Terzaghi was the most suitable for the silt-clay soil of this study. [ABSTRACT FROM AUTHOR]
