GEOframe Winter School 2020 - It is time to apply !

The second edition on the Winter School on GEOframe will be held between January 8 and 17, 2020 in Trento, Italy.  The course is devoted to Ph.D. Students, Post-docs, Young researchers interested in estimating all the components of the hydrological cycle (rainfall, evapotranspiration, snow-melting, and river discharge), and the system they will learn allows to work out very small catchments and continental basins as well (e.g. Abera et al., 2017a,b). The system has been also used in operational context in Basilicata.

The aim of the course is to enable participants to run their own simulations and eventually on their own catchments and estimate the hydrological budget components.
With respect to the 2019 Winter School, there will be more practice and more detailed work on evapotranspiration and rainfall-runoff. It will be much more focused on exercises and on getting the water budget performed under various hypotheses on models' structure.


The provisional topics will be:

Teachers will be:

Prof. Riccardo Rigon, Ph.D.
Prof. Giuseppe Formetta, Ph.D.
Marialaura Bancheri, Ph.D.
Michele Bottazzi, Ph.D. candidate
Niccolò Tubini, Ph.D. student
Daniele Dalla Torre, research assistant

The provisional topics will be:

  • January 8 -   Installation and introduction to the Object Modelling System Infrastructure and Jupyter
  • January 9 -   Interpolation of hydrometeorological datasets and elements of parameters calibration with LUCA and particle swarm tools
  • January 10 - Hydrologic Response Units delineation and treatment of spatial features.
  • January 13 - Estimation of evaporation and transpiration 
  • January 14 - Rainfall-Runoff I - Representation of semidistributed models with the Extended Petri Nets. The embedded reservoir (ERM -see also here) and other available models. Discussing  inputs data to models and modelling solutions. 
  • January 15 - Rainfall-Runoff - II  - How Net3 works (see also here). Preparing the topology and the simulation files.  Connecting and disconnecting components. Running modelling solutions. 
  • January 16 - Rainfall-Runoff - III Calibration issues, multisite calibrations and first results production
  • January 17 - Results production and presentation.   Hints for estimating travel times. Crowd-based-hydrology.
To have an idea of the topics, the interested researchers should give look at the material (slides, video etc. of the 2019 Winter School).  The material of the first three days remains very similar (but refined) to the old one. Therefore, for students is possible also to participate only to the second week (at the same cost, but saving some lodging) but, in that case, is mandatory to follow the on-line courses and tutorials  relative of 8-9-10 January topics and having done the exercises before December 15. We will offer prompt online support to them up to that date and no support whatsoever on the same topics later or  between 13-17 of January for clear reasons of course efficiency and organisation.  The refined material of the first three days will be available on the Winter School website  from November 15, 2019.

With respect to the 2019 School, there will be more practice and more detailed material on Evapotranspiration and Rainfall-Runoff. For every 40 minutes of talk there will be 70 minutes of supervised exercise for a total of 8 hour a day of activities. 

Cost of the School is 350 Euros for who will subscribe before November 15, 400 Euros for others. A discount of 20 Euros is granted to fellows of the Italian Hydrological Society (subscriptions for students are available at the IHS-SII site for 10 Euros to students and 20 to seniors). Who attended the last year school can participate free of charge, upon subscription. Inclusive of the costs will be coffee breaks and lunch at the Cafeteria of Department of Civil, and one social dinner for all the schoolmates Environmental and Mechanical Engineering. 

Website for a possible enrollment here (To be active from October 15 2019).

Material for the GEOframe Winter School - Rainfall-Runoff

Here we are introducing some modules for rainfall runoff modelling present in GEOframe. Some of them where actually refined for the Civil Protection of the Basilicata Region.


Schedule

Exercises
  • The set of sim files and the Jupyter notebook are here
  • The Python script by Christian Massari to create automatically the required subfolders. It is here.

Material for the GEOframe Winter School - 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

Material for the GEOframe Winter School - Radiation budget

After having spent time on preparatory topics, but before facing the hydrological processes, we need to cope with solar radiation. The topic was already treated in other posts. However not often in English.

Some very elementary slides about the sun:

Now some more complicate topics

Material for the GEOframe Winter School - Kriging interpolation

Third and fourth days of the Winter School on the GEOframe system about GEOframe are dedicated to interpolation by using Kriging and the use of Particle Swarm Calibrator.

Material for the GEOframe Winter School - Catchments and Hydrologic Response Units delineation

The second day of the Winter School on GEOframe is dedicated to the watershed delineation and hillslope extraction. First the relevant concepts are given. Then GEOframe (Horton Machine) tools are used to get the desired results.
Requirements: if not already done, install numpy and rasterio with anaconda. These will be used to visualise the maps produced by the OMS Horton Machine tools.

Day 2 actual schedule ... We recovered something from the first day.

Work in progress

Material for the GEOframe Winter School - Getting Started with OMS and Jupyterlab

Day first of the Winter School on GEOframe was conceived to give people the taste of what OMS is and how to use it with Python lab. For the Installations, please refer to the Installation page
Not much information about Jupyterlab though. It will be given interactively using notebooks and explaining their contents.
