Announcement

Announcement: Note that the Hydrus-1D software package has been discontinued. While Version 4.17 of HYDRUS-1D will remain available to the public as is, any new developments will from now on be implemented only in Version 5 of HYDRUS. Note that version 4.17 of HYDRUS-1D has recently been fully updated and merged with HYDRUS (2D/3D) (version 3.04) to result in Version 5 of HYDRUS. New features of the one-dimensional part of Version 5 of HYDRUS include new modules PFAS, Cosmic, DPU, Particle Tracking, and C-Ride, as well as updated graphical capabilities, such as two-dimensional z-t graphs of selected variables. More details about Version 5 of HYDRUS.

Download the installation package (e.g. Hydrus1D_4.15.0110.exe) and run it.

Installation Instructions for version 4.14 and older:
Download a self-extracting archive (for example H1D_4_08.exe) and run it. Extract setup files to a temporary directory.

  2. Display of wetting hydraulic functions for hysteretic soils
  3. Triggered irrigation

  5. Graph for observation nodes for major ions, EC, and SAR

Fixed Errors:

  1. Porosity in the soil catalog for the Brooks and Corey model was updated based on Rawls et al (1982) (originally this value was based on the RETC report (van Genuchten et al., 1991)).
  2. Error in the Rosetta Module (Neural Network Prediction) causing breakdowns under certain circumstances.
  3. Error in calculations of the hydraulic conductivity in the Durner's (1994) model

Version 4.15 - August 4, 2012

New Features and Changes:

  1. Substantially extended help file
  2. Fully updated manual
  3. Input of sublimation constant and initial snow layer.
  4. New conversions of constants (EC, osmotic potential) for the salinity stress response function.
  5. Support for the silent (unattended) installation

Fixed Errors:

  1. Conversion of some first- and zero-order rate constants with respect to length units

Version 4.14 - December 13, 2009

New Features and Changes:

  1. Updated conversion of ECe to ECw values from the Maas [1990] database.

Fixed Errors:

  1. Calculations of LAI or Surface Cover Fraction based on Bear's Law.

Version 4.13 - October 31, 2009

New Features and Changes:

  1. Version 2.1.002 of HP1 (see HP1 page for changes)
  2. New part of GUI supporting HP1
  3. Conversions of the Mass database for the threshold-slope salinity stress model from electric conductivity to osmotic head.

Fixed Errors:

  1. Mass balance error in the dual permeability model when different Ks values were used in the matrix and fracture domain.
  2. The main window might have remained locked after closing the Profile module.

Version 4.12 - April 11, 2009

New Features and Changes:

  1. New additional output (e.g., solute fluxes for observation nodes and profiles of hydraulic conductivities (thermal and isothermal) and fluxes (liquid, vapor, and total)). Brief description is here.
  2. An option to convert projects to earlier versions has been removed.

Version 4.11 - March 21, 2009

Fixed Errors:

  1. Fixed H2D_Clci.exe file that was damaged during digital signing and unable to run in version 4.10. As a result, it was not possible to calculate inverse problems.

Version 4.10 - February 15, 2009

Fixed Errors:

  1. A minor error in initialization of a variable (Altitude for some meteorological calculations) for the new Fortran compiler was fixed.

Version 4.09 - January 16, 2009

Fixed Errors:

  1. A newly used compiler initialized several variables differently than the old one, resulting in incorrect format for several graphical outputs.

Version 4.08 - January 4, 2009

New Features and Changes:

  1. Compensated root water and solute (passive and active) uptake based on Simunek and Hopmans (2009)
  2. Executable programs are about three times faster than in the standard version due to the loop vectorization.

Fixed Errors:

  1. Initial distribution of solute mass between different phases.

Version 4.07 - December 6, 2008

New Features and Changes:

  1. Surface Energy Balance (i.e., the balance of latent, heat, and sensible fluxes) for bare soils can be considered.
  2. Daily variations of meteorological variables can be generated by the model using simple meteorological models.
  3. The Mass Balance (Inverse) Information dialog window enables to display texts larger than the capacity of the Edit window.
  4. Preliminary (at present rather simple) support of the HYDRUS package for MODFLOW.

Version 4.06 - September 11, 2008

New Features and Changes:

  1. HP1 – support of dual-porosity models, higher user friendliness for HP1
  2. The Per Moldrup’s tortuosity model was implemented as an alternative to the Millington and Quirk (1960) model.

  2. Linking of optimized parameters of different soil layers
  3. Constant mobile water content in multiple layers (in the Mobile-Immobile Water Model) when optimizing immobile water content

Fixed Errors:

  1. HP1: The command “Create default PHREEQC.tmp file” instead opened the technical manual.
  2. Disabling “Altitude” in the input dialog when Hargreaves equation to calculate potential ET is used, since it is not needed.
  3. The dual-porosity model with pressure head exchange sometime caused a crash of GUI.

Version 4.04 - May 25, 2008

New Features and Changes:

  1. Option to specify the nonequilibrium phase concentration initially at equilibrium with the equilibrium phase concentration

Fixed Errors:

  1. Fixed error – production of the second solute due to degradation of the first nonlinearly sorbed first solute
  2. Fixed error - the velocity correction due to the temperature dependence of the Henry’s law coefficient for the second and further solutes (see eq. 3.12 of the manual).

Version 4.0 - January 2008

  1. Vapor flow
  2. Coupled water, vapor, and energy transport
  3. Dual-permeability type water flow and solute transport
  4. Dual-porosity water flow with solute transport and two-site sorption in the mobile zone,
