Hydrology 2020 lab

This is the material of the Laboratory Class of the Hydrology Class 2020. You can find the class material here. 

1: Programs Installation
 2: Installations problem solving

Also here, same topic, by Concetta D'Amato (YouTube2020, Data). 

2020- 04-29 - Exercise with Python
2020 - 05-06 Lab Work on Precipitation extremes
2020 -05-08
2020 -05-13
2020-05-15 - Storyboard of the class 

Simulations with Richards 1D:
2020-05-20
  •  The grid creation (YouTube2020)
  • A series of Notebooks with planned simulations for your inspiration (please pay attention that the environment geoframe-vicenza already contains some of the scripts that needed to be uploaded explicitly the examples)
2020-05-22
Estimating evaporation and transpiration


Additional material (on radiation)

We need radiation too. The topic is very boring (or technical?) but necessary to who want to do evapotranspiration and snow. After all radiation moves it all.

About Hydrological Models


Starting from some philosophy I try to give an idea of what a scientific model is, on the example and limitations of the Galileian approach. I claim that hydrology is mostly a science where you have to move away from experiments and you have the deduct the models from observations more than experiments. This introduces some difficulties and arrive to the arrive to the conclusion that we do models of the data and models of the models of the data. Because of the presence of multiple phenomena interacting, hydrology gain a space in the science of complexity. But yet we do not know how to characterize it, if we do not use the classical mechanics and/or the usual thermodynamics. As a matter of facts, we have to deal with an entire zoo of models born with different scopes and evolved sometimes erratically.But at this point is where we do stand.
Please find the slides here, and  the Vimeo video where I comment them here (an older YouTube video  here).  I also makes a little summary of the talk here.
These slides can ideally be followed by those I used during the 2020 GEOframe Winter School:

Entrance Of The Rivers


Beloved of the rivers, beset
By azure water and transparent drops, 
Like a tree of veins your spectre 
Of dark goddess biting apples: 
And then awakening naked 
To be tattoed by the rivers, 
And in the wet heights your head 
Filled the world with new dew. 

Water rose to your waist,
You are made of wellsprings 
And lakes shone on your forehead. 
From your sources of density you drew 
Water like vital tears 
And hauled the riverbeds to the sand 
Across the planetary night, 
Crossing rough, dilated stone, 
Breaking down on the way 
All the salt of geology, 
Cutting through forests of compact walls 
Dislodging the muscles of quartz.

Poem by Pablo Neruda

I've see it in Muscles of Quartz blog by Sean Turner
