Turbulence

Want to start with turbulence ? Start first with fluid dynamics:
  • George Batchelor [Old, but classics]
    • An Introduction to Fluid Dynamics ( I have the feeling to be able to do better in some parts - but without trying it how one can say ?)
Some freely available resources:

Regarding Turbulence itself, I would start from on-line resources, and the first reading could easily be:
which could continue continue with some selected topics by

If I have to choose just other three references, I would select (in brackets [ ] Shalizi's -see below-comments, in  ( ) my comments) :
  • George Batchelor [Old, but classics]
  • Uriel FrischTurbulence: The Legacy of A. N. Kolmogorov [An excellent introduction, very strong on defending Kolmogorov's work from misunderstandings and invalid criticisms.] One paper that summarizes Frisch view is here
and a different, but, in my opinion in the long-term the winning perspective:
Of the latter this paper by David Ruelle can be a complement.

Also the old classic book by Tennekes and Lumley  is available, legally or not, on-line, here.

Other stuff  which is intriguing me, are random cascades (and turbulence), a topic that I came to know through the work of Ed Waymire, and that you can come close by reading:
Also interesting is the works on rinormalization group and turbulences of which this is a google synthesis.

Finally, you can look at the Cosma Shalizi's bibliography. Huge and overwhelming indeed, it was the starting point of this my own post.

Snowflakes (is Christmas time after all, and I live in a boreal place)

Christmas time remembered me to give a look to snow crystal formation literature and models. To my surprise, a definitive (thermodynamic) theory of their formation does not exist. This is what can be deduced form the review paper by the K.G. Libbrecht (2005).  Even if in two subsequent papers (2012 and 2013) he tries to delineate a possible path towards a comprehensive theory. Actually the attention to Libbrecht paper was brought to me by a paper on a three-dimensional model of snow-fakes (fakes ;-), not flakes) by Gravner and Griffeath. For a classification of snow crystal, Magono paper, would be fine. I am looking forward to read them all (starting from the Libbrecht review and his two most recent papers, which seem to add something) and complete this post more appropriately eventually. For the moment, be happy with the bibliography.

Some of the  references could look strange (e.g. Fu et al., 2006). In that case, I was looking for literature in the area of fractal surfaces. Something else should be available.  In particular, I was looking for a papers by J. Nittman and  Eugene Stanley (a "star" among the "fractalists"). In any case, growth of this type of forms is pretty general and ubiquitous (as shown in many papers, and in particular, in Ben Jacob's ones).

I also indulged in adding some papers about snow crystal methamorphism. This is not the topic of the post, but for the moment I keep trace of them in here. Other papers were just added for getting some general reference to crystal growth (e.g. the Krug's one, and those looking to micro-meteorological aspects of the growth).

Interesting readings are also addressed in this older post.

USGS r-packages for hydrology

As I learn AGU Fall meeting, USGS is committed to develop various R Packages to help analysis of hydrological data.

These packages include:
  • GLRItcl
  • usgs-r.github.com: Splash page for USGS-R organization
  • EflowStats: Calculates Hydrologic Indicator stats and fundamental properties of daily streamflow for a given set of data
  • EGRET: An R-package for the analysis of long-term changes in water quality and streamflow, including the water-quality method Weighted Regressions on Time, Discharge, and Season (WRTDS)
  • EflowStats: Calculates Hydrologic Indicator stats and fundamental properties of daily streamflow for a given set of data. A related poster, presented at AGU Fall meeting 2013, can be found here.
  • USGSwsBase: Base USGS water science R functions.
  • surragateRegression
  • dataRetrieval: This R package is designed to obtain its water quality sample data, streamflow data, and metadata directly from either the USGS NWIS (National Water Information System), but it allows for user-supplied text files as inputs. The program is designed to ingest the data directly into R and structure them into file structures suited for EGRET analysis.
  • USGSwsQW: Water quality USGS water science R functions.
  • USGSwsStats:Statistic USGS water science R functions.
  • USGSwsData: Data sets as data.frames and as text files for examples in the USGS core pacakges
  • USGSwsGraphs: Graphical USGS water science R functions
  • restrend
  • rloadest
  • DVstats
  • NWCCompare
  • rGDP
  • functionCollection
All of them can be retrieved from the USGS-R Github repository. Link to other R packages useful for hydrology can be found at the main R post.

The Abouthydrology mailing list (at googlegroups)

Tired of keeping your own (and often outdated) list of colleagues to advertise your conference session, Ph.D. and postdoc positions, or other research opportunities?
Do you have a free software program or textbook of interest to the hydrologic community?
Wish you could just send one email and have it reach hundreds of your colleagues?

  Welcome to the About Hydrology mailing list! This acts the very same way the Gilbert Club list does for geomorphologists in being used to send announces about events, Ph.D. and post-doc positions, new books, open source software, AGU and EGU sessions and so on. All about hydrology, obviously.

The list has so far  (January 2017) more than 2000 active subscribers, and therefore sending around information through it is pretty effective, and save you the weight to maintain your own list of email addresses. Besides any message is also sent to the [hydrosci-l] mailing list that counts another 200 or so subscribers.
To subscribe go to the page: https://groups.google.com/forum/#!forum/abouthydrology  or Search “AboutHydrology Google Group”. Maintaners of the group are me, Stacey Archfield, and Giuseppe Formetta.

GEOtop 2.0 at AGU 2013 - II - The Cryosphere

In this marathon I am doing at this Fall AGU Meeting, I am also giving a second talk about GEOtop 2.0. But this time I talk about the simulations of the snow modelling and the soil freezing.
The presentation is mainly based on the work initiated with Stefano Endrizzi and Matteo Dall'Amico thesis, and subsequently pursed together with Stephan Gruber of Zurich University, now at Carleton University. The two reference papers are Dall'Amico et al. 2011 and Endrizzi et al., 2013, cited in the talk, but also the work in Gubler et al. 2013 is extremely relevant for all the testing it performed on the models
.
So clicking on the image, as usual, you will gain access to the presentation. While, in the first post I took the occasion for adding the References of GEOtop, in this case I just collect the main presentations on the topic that you can find below.

GEOtop 2.0 at AGU 2013

I was invited to talk at a Fall AGU Meeting section about High Resolution Hydrological modelling. This is the topic of the H21M session of the meeting.  The following, below (clicking on) the figure is my interpretation of the topic.

I describe GEOtop 2.0, present a few case studies, and took the occasion to do some synthesis of this work. All the merits go to my co-authors, that in the last years strongly believed and pushed GEOtop beyond what it was. The presentation does not cover the cryospheric part of the models, which will be the focus of the second presentation.

This other posts covers my second presentation at AGU, talking about how the cryosphere is modeled in GEOtop 2.0.

The Presentation at the Mountain Research Initiative Key Contact Workshop held in Berkeley Dec 8, 2013

After a few years, I am back to San Francisco AGU meeting. It is  a place where I grew up, since I participated ten times in 22 years.  For the very same reason that the fall meeting is crowded with more than twenty thousands of geophysicists coming from all around the World, many side meetings are organized. The MRI side meeting is one of these, and I participated.
The meeting involved a small group of people (around twenty) but was really interesting and productive. One can find all the contribution to discussion on the MRI website. At the moment, you can see my contribution by clicking on the image above.

MeteoIO

MeteoIO is a library that provides various interpolation methods for 1D and 2D data. It has been used for the SnowPack and Alpine3D models, and recently we started also to use it for GEOtop. GEOtop has its own interpolation routines but MeteoIO is supported by a larger community of developers, and therefore, why reinvent the well again and again ?

For this reason in  GEOtop 2.0 MeteoIo was added. Models uniforming to MeteoIO conventions can also use the INIShell Java program that provides a graphic user interface "for free".

On october 23th a small seminar was held in Eurac, Bolzano,  to illustrate the use of MeteoIO. The presentation by Mathias Bavey can be found here.

Mathematics for the Fluid Earth

"The fluid Earth is an excellent example of a forced, dissipative non-equilibrium system dominated by nonlinear processes and featuring multi-scale interactions, so that its understanding can be approached using the tools of dynamical systems theory and non-equilibrium statistical mechanics. The understanding of the statistical properties of a system under consideration is crucial per se and in a variety of applications, especially when considering large fluctuations which may result into extreme events of relevant impact. The differential equations that describe mathematically the fluid components, in particular the Navier-Stokes equations and their many variants and reductions, are at the core of the work of any analyst working in nonlinear PDEs. The many fundamental questions still open are often precisely the questions at the heart of the link between analysts and geophysicists."

A Java Implementation of R !

Since I am becoming a Java programmer, and an R evangelist,  I found very interesting the FastR project whose scope is to provide a Java implementation of the R language. This would be really interesting, especially thinking to a possible integration among OMS and R, which would be very helpful for data management and I/O for model components.

Jan Vitek, one of the authors of the code, gave a nice presentation about, that can be found below the image.

Any comment is left to the readings and to the trial of the software. Eventually,  other material and  code itself, can be found at github

Process based models of landslides' triggering. My talk at Cosenza on November the 7th

Last November the 7th, I was invited to give a talk about process-based models of landslides triggering.  My talk (you can find it here) was mainly about the key elements for describing hillslope hydrology and stability, and inherits a lot on my previous talk at the Praia a Mare Summer School.
However there is some new material, and especially I mentioned the work made for embedding GEOtop into OMS, and the recent work we made for the IWL Round Robin.
At the seminar there were other three interesting topics by Giovanna Capparelli, Fausto Guzzetti (see also the website of his group) and Roberto Greco. The latter, one of the author of the IWL organisers and designer of the IWL3  "round robin". At the round robin (we did not arrive in time for presenting our work) some Spanish guys won (with the best predictions of the suctions of the experiment) by running a model that solves the coupled Richards and Stress equations.  As it will result for giving a look to the slides, our trial was not successful: but because we tried to reproduce contemporarily both suction and water content. We fail. This can only means that the soil water retention curves used were not appropriate. We do not know however if the case is that the vanGenuchten parameterisation is failing (and/or Mualem that gives hydraulic conductivity) or if the parameterisation is actually time-dependent, as the strategy used by the Spanish guys seems to suggest. 
In my opinion, it is reasonable that soil water retention curves vary after soil starts to move, but I  am not sure that a dynamical parameterisation would be required before the failure time.

Regional Risk Assessment methodologies for water related hazards and climate change by Paolo Ronco et al.

The above was the title of the seminar held today at CUDAM of University of Trento. The speaker was Paolo Ronco  of Ca' Foscari University of Venice.
The seminar was a positive meeting of a few but qualified and interested people. The entire seminar is now visible on-line by clicking on the image above.

Climate Change Adaptation strategies - Brescia Workshop on October 10 2013 presentations

Among the duties for the Alpine Convention's Water Platform there is the organisation of workshops with the scope to share experiences of best practices among the alpine countries. Best practices, in this case for the adaptation to Climate Change with respect to Flood Risk and Water Management.

In Brescia, last month, officers of Italy, Austria, Germany, Switzerland, Slovenia met and developed an interesting conversation on these topics.

Unesco Water Glossary

Diego Avesani, one of the Ph.D students of Alberto Bellin, brought to my attention the new UNESCO  Water Glossary. You can retrieve it by clicking on the image below.

UNESCO has a lot of water related programs that you can browse at their website.

Clima Trentino (About Trentino Climate and adaptation to Climate Change)

I will use this page to collect all the material about Climate change impacts related to Water and Hydrology (and at relatively small scales) going towards the Fitfth Water Conference of the Alpine Convention (to be held in September 25-26 2014) which will cover this topic in detail.
I will start with the material (In Italian) of the meeting Clima: quale futuro per la Terra (Climate which future  form Earth) which I co-organized with Clima Trentino the recent October 21.
You will find two presentations the first a very nice introduction to climate change and adaptation by Antonio Navarra, and the second about the Italian strategy to Climate change adaptation by Sergio Castellari. Both of them of the  Center euro-Mediterranean for  Climate Change (CMCC).

The Italian National strategy was finally disclosed yesterday by the Italian Ministry of Environment,  Andrea Orlando, and can be found here.

Yesterday I also met Marcela Olmedo, an anthropologist who works on Adaptation of Climate Change and Water. She is the author of an interesting blog: http://www.environmentalanthropology.net and her woork on climate change adaptation can be found here.

The presentations and work of the Workshop on Climate Change Adaptation held in Brescia on October 10th, and organised by the Water Platform of the Alpine Convention, can instead be found here.

The seminar on the KultuRisk EU Project, held in Trento November the 5th by Paolo Ronco of University of Venice, can be accessed from here.

WorldDEM dataset

My Ph.D student Wuletawu Abera brought to my attention the WorlDEM data set. It will be a global DEM with unsurpassed precision covering all the Earth (Pole to Pole, not as SRTM from 60 degree North to 60 degree South).
The detail of this product can be found in the GISResources website. Unfirtunately, it seems you have to pay for it.

The "summer" School on Object Modelling System in Trento 2013

The "summer" school started yesterday.  All the material prepared by Olaf David, Gabriella Turek and Giuseppe Formetta is here (link no more available: but the link beow work) where you can find presentations and code.
If you are probably interested to OMS3 tools, you can probably start with the 2016 Summer School Material now.


In day one there was a general overview of OMS and what it does, through the presentations of Olaf David (presentation here), Gabriella Turek  and Giuseppe Formetta (presentations here). The lectures and the video can be found here at the LODE site by Marco Ronchetti.

Monday lectures covered mostly an overview of the system, including:


In the second day we started to approach the concept of components and see some first example of components integration.



Third day starts with the Hello World example. Then continued with Two Component and Three Component.  After the coffee break we went into First Class Object Parameters. Next class examined was Conversion SPI for connecting components through some conversion of types. Bulk connect or how to get one component output for many component input.  At Name Alias substitutes long names component with shorter alias. Component logging to have a fine control on what you want to output, for instance in different phase of a projects. Simple Iteration for knowing how to iterate more time the execution of a command.

Fourth day is dedicated to applications. Giuseppe Formetta  talks about JGrasstools, JGrass-newAGE and the calibration algorithms embedded in it.




In the afternoon we give a look at the porting of the Sparrow program made by Gabriella Turek. Whilst in FORTRAN the program allows to understand how to integrate C/C++ legacy code.

2016 Summer school is here.

Enjoy !
