Hydrology 2024

The Course of Hydrology 2024 will be 90% similar to last year class with minor modifications.  Indication of tools used etc can be found at the 2023 Index (3 minutes reading). Here you'll find the material of the classes including slides, old and new videos. Hydrology is an exciting field since water is so important for life and human activities. Here a  brief introduction from a National Geographics post. 

Companion of this post il the laboratory page on which you find material for your exercises. 
Lab page is at this link. 

Classes and related material

You can find:
  • Storyboards is a summary, usually in Italian, of the lecture
  • Whiteboard is an explanation of a particular topic made on the whiteboard (using Notability on the iPad)
  • Slides are commented in English
  • Videos are available to comment the slides. They are usually recorded during the lectures with no editing at all (which would be too much time expensive). 2024 Videos are uploaded to a Vimeo Showcase that can be found here. 
  • Additional  information (only for the brave or the curious) and references are in italics

2023-02-20 - Ground based Precipitations and their statistics Separation snow-rainfall - measure of precipitation

In this part of the class we describe where it rains and how much it rains using statistical concept. One important objective is to understand what are the extreme precipitations for their importance in engineering. 
2024-02-26 - 2024-02-27  - Statistics of extreme precipitations

 Some reviews on statistics - Return Period
Extreme precipitations  (Storyboard2020)
Distributions Storyboard2020

Determination of Gumbel's parameters
Extreme precipitations  II
2024-03-05 -Beyond Gumbel
A summary about the extreme precipitation estimations (Whiteboard)

Water in soil and aquifers 
 (Storyboard2020)
Once precipitations arrive to the ground surface they either infiltrate or generate runoff. We first state how they infiltrate and, actually how water behave in the soil and in the ground. We talk about the complexity of the Earth surface that contains life and call it, the Critical Zone. To study infiltration we introduce the Darcy and Richards equations of which we explain the characteristics.

 - The Richardson-Richards equation  (Storyboard 2020)
2024-04-15

 Runoff Generation and propagation (Summary 2020)

Once the rainfall gains the terrain, it can infiltrate or producing runoff. In the next we discuss the main mechanisms that produce runoff.
Q&A - Runoff - Runoff 2022

2024-04-22

Runoff moves on the surface of the terrain according to the de Saint-Venant equation. In the following the equation is derived in the 1D case.

Evaporation generalities (Storyboard2020)

A consistent part of root zone and surface water evaporates and returns to the atmosphere to eventually form clouds and precipitation again. The process follows quite complicate routes and is different when happening from liquid surfaces, soil or vegetation (and BTW animals).  In this group of lectures we try to figure out the physical mechanisms that act in the process and give some hint on methods to estimate evaporation and transpiration with physically based models.

The Hydrology Class 2020

To have an idea about this class, please look at the Syllabus slides below.  This year the class will be 90% similar to the one of the last year.  Laboratory work will be (mostly) concentrated in May and June. March and April up to Easter will be mostly spent to develop the theoretical parts.
Lectures  and lab classes will be recorded and uploaded on my YouTube channel.
The intermediate exam will be written with 3 questions about the topic treated to which the student will be asked to answer with text, figures and formulas. The final exam will be a discussion of the exercises provided by the students int the form of Jupyter notebooks plus a short Python exercise. Each of the exercises will be discussed separately and by booking an appointment with the professor before the formal date of the exam or at the day of the final exam. The touch-screen at the first floor of the Mesiano building  will be used for the presentations.

This Hydrology class aims to explain the physics (meaning the mathematical equations and their phenomenology) and, in some cases, their statistics (i.e. the distribution) of the basic hydrological processes (precipitation, runoff, infiltration, evaporation and transpiration)
Students will be required to: being able to derive and comment the hydrological equations above mentioned and to do some statistics on hydrological data. Particular attention will be dedicated to the derivation of the statistics of extreme rainfall.

They will learn how to delineate a catchment for digital elevation models through some appropriate tools. Besides students will be requested to get some basics of the tools that will be used to estimate the hydrological fluxes (using a GIS, Python, and other tools, among those in GEOframe).
They will be required to be able, by means of some models provided by the instructors the main hydrological fluxes and represent them at catchment scale.

This is intended to serve as a basis for getting further knowledge and
  • prevent, manage, control floods, landslides and snow-avalanches
  • manage irrigation
  • estimate water availability for hydropower production
  • forecast roads freezing
  • estimate soil, roads, or snow temperature
  • forecast snow water equivalent and snow height
Assuming that the student will take a master in Environmental Engineering at Trento University, Acquedotti e fognature, Modelli idrologici, Ingegneria fluviale, are classe that request the knowledge communicate in this Hydrology class. 


The first part of the course, until April 3, will be dedicated to the presentation and discussion of theoretical concepts through lectures that will be videotaped and uploaded on the course's YouTube channel (or Vimeo). The lessons will cover 4 of the five hours per week. The fifth hour will be devoted to simple exercises with Python and Jupyter lab and to the preparation of the data necessary for the projects to be completed in the second part of the course in groups of two or three students.
The student must take care to understand the hydrological concepts and discuss them with the lecturer. The first twenty minutes of each lesson will be devoted to the discussion of the topics covered in the previous lesson. Each group will have to prepare one question or comment to which the teacher will answer. A summary of the lesson will follow, followed by the actual lesson. The second part of the course will take up the theoretical themes of the first part and using the tools made available to the GEOframe system. Students, in groups of two or three, will have to:
  • Analyze a series of rainfall and hydro-meteorological data with the use of Python 
  • Estimate the intensity-duration-frequency curves with the methods presented in the first part of the course using the data of a hydro-meteorological gauge station
  • Design, under the supervision of the tutor and the teacher, and run some infiltration simulations in complex soils and discuss the results.
  • Design, under the supervision of the tutor and the teacher, and perform the calculation of evaporation and perspiration in a chosen site

Used Software

There is no engineering without using models. During the class will be used various open source softwares and resources:
All these resources are free, besides being open. For installations requirements, please see the GEOframe winter school material here. For understanding a little more about this material, please look at "Getting started with Docker OMS and Jupyterlab" post.

     References

    The lessons will be video recorded and made available. Each lesson will be given through slides in English which will be delivered to students in advance. When necessary, the lessons will be accompanied by appropriate in-depth articles. There is no real text because the course, even when it is fully in the hydrological tradition, elaborates the concepts in a contemporary way and uses innovative tools.

    As general reference texts we recommend:
    • Bras, R.L, An introduction to Hydrologic Science, ISBN-13: 978-0201059229, 1989 - ISBN-10: 0201059223, Addison-Wesley (July 1, 1989)
    • Brutsaert, W., Hydrology: an introduction, ISBN-13: 978-0521824798 - ISBN-10: 0521824796, Cambridge University Press, 2005
    • Dingmann, L., Physical Hydrology, ISBN-13: 978-1478611189, ISBN-10: 1478611189, Third Edition, Waveland Press, 2015
    • Freeze, A. ; Cherry, J., Groundwater, 1979
    • Lu, n. and Godt, J.W., Hillslope Hydrology and Stability, Cambridge University Press, ISBN-13: 978-1107021068, ISBN-10: 11070210652010, 2013

    These books represent a shareable review of phenomena and hydrological modeling but the methods they present are not necessarily those used in the course. The course, also for reasons of time, presents a selected and limited perspective of the subject that the texts cited dissect from various points of view.
