Riccardo Rigon.  


I was a Ph.D. student at the University of Trento.  I lived between Trento and Venezia (Venice) but I am from Vicenza, all in Italy. I also lived in College Station (TX, Texas A&M) and Fort Collins (CO, Colorado State University) and visited frequently Boston (well was long time ago, MIT).  Now I am pretty stable in Trento where I work as Professor.    I graduated in Physics and have a Ph.D. in Hydrodynamics.  You can see more about me at the CV pages on the AboutHydrology blog  I started the GEOframe project

Day 7 - Looking forward


We really enjoyed to work with this year students. We had an average synchronous participation of 25 but others were following asynchronously. The work is not finished until everybody who wants complete their exercise on a catchment. That will be the also the requirement to have recognized  the credits, besides the certificate of participation. The GEOframe crew will be happy to give you support for the next two months for complete the tasks required. New stuff is incoming in GEOframe that is a living a growing system. For that you will be alerted through the WinterSchool mailing list and the post in this blog. 

The first news is that we are:
  • smoothing down the process to create HRUs with the help of  the friends of Hydrologis. A preview of the tool is working under the stand-alone Horton Machine, of which you can learn in this AboutHydrology blogpost. 


The second, this is an old new)  is that GEOframe is not limited to models based on partial differential equations. We have also WHETGEO 1D (and 2D incoming) which stands for Water, HEat and Transport in GEOframe:
  • WHETGEO-1D. Developed by Niccolò Tubini for his P.h.D. e used it extensively in our class of hydrology. Therefore for the documentation in Italian, you can give a look to here.  We will provide soon documentation in English
  • Lysimeter GEO.  Being developed by Concetta D'Amato for her Ph.D. , building on the shoulders of Niccolò and dr. Michele Bottazzi's  (GS) Prospero model.  On Lysimeter Pro you can find two webinar in English that can also partially serve to introduce WHETGEO-1D. They are at this link. 
The local (uniTrento) GEOframe crew repeated indefinitely within the screens. From left: Giuseppe , a little in front, Concetta , on the back Riccardo, then Martin and Niccolò.

Next year School will be in two session. The first one in December, possibly the 15-16-17 to make installations, extracting the geomorphology of the catchments, preparing and interpolating the datasets. This will be held in remote, as this year. The second one, between 10 and 14 of January, both included, for evaporation, transpiration, rainfall-runoff, exploring alternatives, finalizing student's work.  Use GEOframe and spread it around! If you would like to become a developer, please let's us know. We will provide the appropriate training.

GWS2021 - Day 6 - Adding features to the rainfall-runoff modelling

GEOframe aims to simulate the whole hydrological cycle. About evaporation and transpiration was already talked about on Day 4 However, several other aspects can be accounted for in GEOframe for obtaining a realistic representation of the hydrological cycle. The scope of this day is to progressively introduce new aspects and features. 






GWS2021 - Day 5 - Rainfall Runoff

Finally we go to the core of the School, the modelling of the Hydrological cycle. However treating the geomorphology and the inputs was hydrological modelling too. According to the rule garbage in - garbage out, whatever the core models are, their result cannot be any good if the inputs are wasted.

Day 4 - Evaporation and Transpiration

Evapotranspiration accounts for most of fifty percent of the terrestrial hydrological cycle. We illustrate here some ways to estimate it with the tools offered by the GEOframe system

Next day

Day 3 - Exercises by Students

 Participants to the GEOframe Winter School are assumed to perform the analysis of a catchment. Here we are collecting their work  areas, and in the next weeks, hopefully, the result of their work. 



So, please do not hesitate to communicate to us which catchment you are thinking about. in FIFO order:

Material for day second (January 8 2021) - Spatial interpolation and kriging

 

You can download the material for day second (January 8 2021) from this link.

 

 


After unzipping the folder you can see the typical structure of a OMS project. This is better explained in this previous blogpost. If you are reading this in advance, please take a little time to understand what OMS is and why it is like this.

 

During day 2 (8 Jan 2021) we will move to the "classical" interpolation problem: kriging algorithm will be explained and applied for interpolating measured rainfall and air temperature to each hillslope of the main river basin. All the material come with the .zip file, however, for your convenience, the slides are also available separately at the link below.

 

The theoretical part of the class in subdivided in three parts:

    The spatial interpolation problem and the kriging algorithm: the concept 

    The kriging algorithm: the equations 


Data Analysis with Pithon, Jupyter and Pandas



  • The experimental and theoretical variogram

  • The leave-one-out (LOO)


Exercises

In the OMS3 project distribute you will find:

    data, a folder containing the model input

    simulations, a folder containing the scripts for executing the models.

    doc containing the pdf of the lectures

    Jupyter containing a group of notebooks which illustrate the inputs and outputs of the simulations


What the other folders contain is explained in the OMS3 related post (see The OMS working environment).

Further information on the tools used and reference to the material of the previous Winter Schools can be found here.

During day 1 (7 Jan 2021) we will focus on the geomorphological analysis of a river basin. Starting from a digital elevation model we will extract the main river basin and we will split it the hillslope-link structure appropriate for executing the GEOframe models. All the material come with the .zip file, however, for your convenience, the slides are also available separately at the link below.

 The theoretical part of the class in subdivided in three parts:


  • Principal gemorphological attributes practice


  • Principal derived quantities with the Horton Machine


  • Watershed partitioning in practice


For the exercises

In the OMS3 project distribute you will find:

    data, a folder containing the model input

    simulations, a folder containing the scripts for executing the models.

    doc containing the pdf of the lectures

    Jupyter containing a group of notebooks which illustrate the inputs and outputs of the simulations

Installations for Mac Users

The main reference for Mac OS users remains the first post. Please give a look in any case to the slides and the videos.  

First installation is made with the installer found at the Anaconda site:


You have 2 options: Installing the graphical interface or installing the command line (Teminal) interface.


After having installed Anaconda, please dowload the Python4GEOframe env:

if you download the zip file, you have subsequently to unzip it. Then within the terminal go into the directory/folder where you have save the unzipped files and execute:

(base) your environment here ~ % conda env create -f geoframe_rossano.yaml

The environment creation can take several minutes. After it has been created you can start the Jupiter lab environment by issuing the command:

(base) your environment here ~ % jupyter lab



You finally get the entry point for workin in Jupyter lab. Several Kernel are visible. During the GWS2021 we'll use the Python 3 Kernel, the first one on the top left.
