Dear R and hydrological/environmental community,

I would like to draw your attention to hydroPSO, a newly developed R package for the calibration/optimisation of (complex) environmental models.

hydroPSO implements a state-of-the-art Particle Swarm Optimisation (PSO) algorithm, which is a global optimisation technique with a surge of attention given its flexibility, ease of implementation and efficiency.

Key features of hydroPSO are:

  1. Model-independent calibration engine
  2. Minimal user intervention to define I/O functions for interfacing hydroPSO with the model code
  3. Several fine-tuning options to customise the calibration engine (for advanced PSO users)
  4. Sensitivity analysis included, using the Latin Hypercube One-factor-At-a-Time (LH-OAT)
  5. Several functions for post-processing of the calibration results

hydroPSO is already available on CRAN:

http://cran.r-project.org/web/packages/hydroPSO/

you can install it with:

> install.packages("hydroPSO")

This package includes a vignette (tutorial) showing how to calibrate SWAT-2005 (http://swatmodel.tamu.edu/software/swat-model/) and MODFLOW-2005
(http://water.usgs.gov/nrp/gwsoftware/modflow2005/modflow2005.html) for real-world case studies.

You can download the vignette and all the files required to follow the two case studies from:

For assistance/bugs report/comments contact/collaboration do not hesitate to contact the authors:

Kind regards,

Mauricio Zambrano-Bigiarini, PhD
