You are not assumed to know Python or Java to participate in the School. However, GOFRAME programs run on Java 11. Input/Output of models will be treated by using some scripting in Python. We will communicate the appropriate notions during the classes but the interested can find plenty of courses on the web (for instance this comes from SciPy 2018. Other from SciPy here.)

GENERALITIES
GEOframe is a system for doing hydrology by computer. By saying that it is a system, we emphasize that it is not a model but an infrastructure that can contain many differentiated modelling solutions (some tens of that) that are built upon model components. This is because GEOframe leverages on the Object Modelling system-framework (v3) that allows to connect modelling components to solve a specific hydrological issue together and having many alternatives for its mathematical/numerical description. This infrastructure allows adapting the tools to the problems and not vice versa. GEOframe has been applied to hydrological simulations from the point scale to large catchments as the Blue Nile, and among those is being deployed to the Po river (the largest in Italy) with great detail. GEOframe is open source and built with open source tools.
CONTENTS
GEOframe contains tens of components that cover rainfall-runoff, evaporation, transpiration, infiltration, terrain analysis tools, interpolation models, calibrations tools, and so on. The Winter School is about using some of these tools to perform the hydrological budget of catchments. The core rainfall-runoff model is dynamical systems (systems of ordinary differential equations) and the school mainly treats their theory and their use in a contemporary way as summarized in these 7 steps. Besides the lectures and the hands-on sessions, the Summer School is the occasion for discussion and experience exchange among senior scholars and young researchers.
PARTICIPANTS' BACKGROUND
Admissions are reserved to up to 30, PhD students and postdoctoral students, young researchers willing to learn the use of the GEOframe tools envisioned for the study of infiltration, energy budget, vegetation transpiration, water budget with process-based models
All students are asked to upload a CV and a motivation letter when applying.
WORKLOAD AND CREDITS
The Winter School which is to be held in English, consists of 8 hours/day of activities for 8 days. The first three days, 20-22 of December, will be dedicated to the installation of the new version of GEOframe-OMS system tools. Lectures will be brief, dedicated to informatics and the exploiting of the concepts of modeling by components, Digital Twin Earth, and most of the time will be used for supporting participants’ installations.
The other five days (10-14 January) will cover:
Catchment and Hydrologic Response Unit delineation
Meteorological variables interpolation with Kriging techniques
Simple evapotranspiration methods
Snow models
Radiation
Rainfall-Runoff modelling
LOCATION & TIMING
University of Trento Polo Mesiano, H1 Room and Online. The three days on informatics and installations will be online. The others online and onsite. The time schedule will be 9-13 and 14-18 CET each of the days. Lectures and workouts will be recorded and immediately posted on the VIMEO Channel of the School and therefore they could be followed off line. Special agreement will be arranged for supporting abroad students with fuse issues.

Subscription to the class is necessary for anyone to receive the information to participate.
Admissions are reserved to up to 30. The students at the University of Trento will be admitted to the School on a supernumerary basis.
The days in December will be held only on-line through Zoom.
A maximum of 15 people may attend the January days in person. In any case it will be possible to follow the School on-line through Zoom.
For those who want the certificate, the Course costs 180 Euros. In any case, the certificate is issued after the presentation of a small project of simulations for which appropriate tutoring will be given during and after the School.
The cost is free for:

Ph.D. students of the University of Trento DICAM and C3A programs,
the participants of the WATZON and WATERSTEM PRIN projects,
members of the Young Hydrological Society of the Italian Hydrological Society
all who want to participate without having a certificate of GEOframe proficiency.

OTHER INFORMATION
The GWS2022 talks and labs will be recorded and made publicly available during the School for self-training through the GEOframe blog (http://geoframe.blogspot.com).

FORESEEN SCHEDULE
December 20:
These
days are dedicated to those who never approached the GEOframe system and pursue
the understanding of how it works.
December 21-22:
January 10:
This day is dedicated to watershed delineation and hillslope extraction. First the relevant concepts are given. Then the Horton Machine tools are used to get the desired results.
Morning session
Afternoon session
January 11:
This day is dedicated to interpolate meteorological data with Kriging.
Morning session
Afternoon session
January 12:
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.
Morning session
Afternoon session
January 13:
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.
Morning session
Afternoon session
January 14:
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.
Morning session
Afternoon session

The specific documentation regards papers and thesis written on the GEOframe components used in this School. Other literature, of general interest, is provided within the presentations given during the course.

Once one has learned to use GEOframe-NewAGE one possibility is that they wants to add some to it. For doing it, you have to learn a little of Java first. In this case, one possibility is to give a look at the dedicated post on AboutHydrology. If they knows a little Java, though, or if they is just curious and bold, he can give a look to this video
Definitely, you realize that it requires just a few lines of code and it is not so difficult (once you have climbed the Java learning hill)
As usual, before starting, download the material at the appropriate OSF page.
Water infiltration in soils is what WHETGEO does but soils are also exchanging water with the atmosphere trough evaporation (from soil) and transpiration (from vegetation). This school day treats with the issue of getting the transpiration right. This task is accomplished by the LysGEO modelling solution whose functioning is the core of the talks.

Please find the material of Day 3 at the OSF page. You find both the OMS3 project for this day and the Gmsh material for creating the grids. Please download them before starting.
After having tried WHETGEO 1D it is time to test WHETGEO 2D. So far we used WHETGEO 2D just internally and never presented to other people, ecept for the thesis by Niccolò Tubini, the developer of the code. So this is kind the debut in society of the program. As the Thesis tells WHETGEO 2D inherit the algorithm of integration from WHETGEO 1D but differs from it because of the more complex topology of the 2-dimensional arrangement of the cells. The day third actually starts with the illustration of how to create an unstructured mesh. For the scope the open source tool GMSH is used Our choice falls on GMSH because it is an open source tool (written in C++) that works under Windows, Mac and Linux. Information can be found at its website.
Next day- Previous Day - Index
The second day of the School is entirely dedicated to play with the WHEGEO 1D in various cases. Just a little more conceptual part is dedicated to the setting of the surface boundary conditions (which, for instance, Hydrus 1D is not able to deal with).
