hydrolakes
This now-completed project is about constructing good subglacial hydrology models for ice sheets and glaciers, implementing and testing them in PISM, supporting actual modeling of a tidewater glacier (Nordenskioldbreen in Svalbard) and an ice sheet (Greenland), and writing a thesis and paper about that.
This paper has been published in Geoscientific Model Development, an EGU journal:
- E. Bueler and W. van Pelt (2015) Mass-conserving subglacial hydrology in the Parallel Ice Sheet Model version 0.6. Geoscientific Model Development 8 (6) pp. 1613–1635, doi:10.5194/gmd-8-1613-2015
Using the model within PISM
The model is part of PISM. It first appeared in the stable0.6 release (February 2014) and will be supported, and possibly improved, in future versions.
The main model described in the paper, which has both till and a linked cavity network, is run in PISM using the -hydrology distributed option; this is the Distributed derived class of the Hydrology class in the PISM source code. The model has an understandable relationship to several other models, but it lacks conduits.
A further simplification removes the linked cavities and instead uses overburden pressure as the modeled water pressure; in PISM runs this is option -hydrology routing, and based on derived class Routing.
The model has a successful verification case. Running the model gives reasonable results for Nordenskioldbreen, shown in Ward's thesis van Pelt (2013).
For Greenland the results are shown in the GMD paper above. They are generated by scripts which live in the PISM source code repo, in directory examples/std-greenland/hydro/.
Build the PDF
To build gmd-hydro.pdf, which requires LaTeX and the Copernicus LaTeX class, do
$ mkdir Copernicus
$ cd Copernicus
$ wget http://www.geoscientific-model-development.net/Copernicus_LaTeX_Package_v_2_7.zip
$ unzip Copernicus_LaTeX_Package_v_2_7.zip
$ cd ..
$ ln -s Copernicus/copernicus.cls
$ ln -s Copernicus/copernicus.bst
$ make
History
The current model evolved from a series of more or less flawed, but mostly serious, attempts to improve the hydrology in PISM. Note that work started in summer 2012.
An old version is in phoenix/ in this repo. The simpler -hydrology routing model is observed to be suitable for locating subglacial lakes in the bueler-igs2012/ subdirectory in this repo. Another out-of-date version is in dampnotes/ in this repo; for some of the history of our attempts to build a better model see dampnotes/README.md. Until July 2013 the latest version was subenhydro.tex, and that was the model used in the last chapter of Ward's thesis. Then the actual englacial part was removed and the name became subhydro.tex. Then Andy changed it to gmd-hydro.tex in an attempt to get things going toward submission to Geoscientific Model Development.
An analysis of the pressure equation implicit in (Bartholomaus et al.~2011) was stripped out of the main paper in April 2014, and published in the Journal of Glaciology. See subdirectory barthextend/.
