It is now possible again to select a specific column from a timeseries file, like it used to (Ticket #635)
This release improves the reliability of PCRaster applications relating to large data sets, includes functional enhancements for the Modflow extension, and fixes several bugs.
This is a bug fix release for 4.0.
We discovered a documentation error for the operations dynwavestate, dynwaveflux and dynamicwave. The manual stated that the Chezy algorithm was the default algorithm to calculate the dynamic flow equation. In fact, it was calculated by the Manning algorithm by default.
If you did not use any global option, your results were calculated by the Manning equation. From now on, without specifying global options, results will be calculated by the Manning equation as well.
If you used either chezy or manning as global option, the corresponding algorithms were used. This behaviour remains unchanged.
To obtain values calculated with the Chezy algorithm, you now need to specify explicitly either --chezy on the command line, #! --chezy in PCRcalc scripts, or setglobaloption("chezy") in Python scripts.
We discovered and fixed a bug in the dynamicwave operation while using the Manning algorithm (Ticket #609). As the Manning algorithm was used as default (see the remarks above) it is expected that your model results will change.
