An improved solution to capillary rise of water in soils

A comprehensive improved solution for the capillary rise of water in soils is presented. Salient features of the formulation, including; consideration of initial soil suction (if any) prior to capillary rising, and determination of water content variation in the capillary region are elaborately discussed. The solution is verified, and compared with existing models, by means of experimental results available in the literature. The improved formulation is more accurate and versatile than previous solutions for capillary rise.
