GWS2022 - Installation


The GWS2022 is approaching.  In this post you will find all the preparatory material of the school indexed. The GEOframe-Verona environment is the GEOframe environment for the Fall 2021. The instructions to install it can be found at this OSF site. Please read carefully the instructions given in the installations.pdf file. 

Tullio Pericoli



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

as explained in these 7 steps.

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.

PARTICIPATION COSTS

Registration deadline January 2, 2022, 12 p.m. (Italian time).

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:

  • students of the Hydrological Modelling Classes at the University of Trento,

  • 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.

    • Anaconda and set up of the virtual environment GEOframe_verona;
    • Java (jdk 11);
    • OMS console 3.6.28;
    • QGIS (or other GIS software mainly for visualizing maps);

  • Variography;
  • The GEOframe Spatial Interpolation Package (SIK);
  • Error estimation.

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

  • Radiation;
  • Exercise on radiation;
  • Phase transformation, i,e the Clausius-Clapeyron equation;

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

  • Hydrological Dynamical System;
  • The representation of Hydrological Dynamical System;
  • Net3.

Afternoon session

  • A few reservoir connected together in a single subbasin;
  • Connect the subbasins by using the topology;

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

  • Adding the interception, routing and reservoirs;
  • Set up the GEOframe-NewAge model.

Afternoon session

  • Analysis of the results in light of streamflow signatures by using the hydroanalysis Python package.
