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