Input data can be edited either using the HYDRUS graphical user interface (this modifies directly the project_name.h3d3 file) or the input data can be modified manually. In the latter case, HYDRUS input files must be stored in an external working directory (sent there by the command File->Export->Export Data for HYDRUS Solver), but then can be imported back into the HYDRUS project_name.h3d3 file using the command File->Import->Import Input Data from *.In Files.
