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:
