Estimating Water Retention and Infiltration Model Parameters using Experimental Data R package HydroMe version 2.1.2 Estimates the parameters of infiltration and water retention models using the curve-fitting methods as shown in Omuto and Gumbe (2009) <doi:10.1016/j.cageo.2008.08.011>. The models considered are those that are commonly used in soil science. Version 2 of the package has new models for water retention characteristic curves.
