My Hydraulic Construction Class 2019

The new class is obviously based on the previous classes:

There are some changes however, partially due to the different calendar. The course is essentially divided in three parts:

Rainfall analysis and statistics
How to design a storm water management system (SWMS)
How to design an aqueduct

Tools

Rainfall analysis and statistics is essential to the design of the storm water system and requires some use of Python in Jupyterlab. Design of the SWMS requires the use of some Python, QGIS 2.18, GISWATER and SWMM softwares. The aqueducts require the use of QGIS and its plugin QEPAnet that implements the tool for estimating pressure water called EPANET. All these tools are open source.

More specifically:

Python - Python is a modern programming languages. It will be used for data treatment, estimation of the idf curves of precipitation, some hydraulic calculation and data visualisation. I will use Python mostly as a scripting language to bind and using existing tools.
QGIS is a Geographic Information System. GIS are an essential tool for who works on landscape or planning infrastructures extended on the territory.
SWMM - Is an acronym for Storm Water Management System. Essentially it is a model for the estimation of runoff adjusted to Urban environment. I do not endorse very much its hydrology. However, it is the most used tools by colleagues who cares about storm water management, and I adopt it. It is not a tool for designing storm water networks, and therefore, some more work should be done with Python to fill the gaps.
EPANET Is the tool developed by EPA to estimate water distribution networks.

Installation Instructions (for Windows) by Daniele Della Torre:

QGIS: http://growworkinghard.altervista.org/qgis-2-18-how-to-install-step-by-step-on-windows/

As you can infer from the previous lines, the class needs to learn some hydrology, some hydraulics and the use of various softwares. As I try to explain in the Syllabus lesson, the first day, there is no space for exploiting all the possibilities implied by the software, nor even to go very deep in the theory of hydrological processes and even in the design of the systems. The student has to become comfortable with the idea that they (singular they) is going to get an introduction to all these topics and they will need further studies to use professionally the received information.

From where do waters arrive

You cannot have an aqueduct if you do not have water to resupply it. So water comes from springs, wells (i.e. from groundwaters) or intakes (surface waters).

Some on statistic of extreme precipitations

These are the lectures that regard the interpolation of Intensity-Duration-Frequency (IDF) curves to rainfall estreme datas. It is covered a little of theory which will be subsequently used to practically interpolate some data sets. These lectures are part of the class of Hydraulic Constructions and Hydrology held at the University of Trento.

Costruzioni Idrauliche 2018

This is the material for the 2018 class in Hydraulic constructions at University of Trento. The material, is being revised during the class and is similar to the last year class. A first difference is that slides will be loaded into an Open Science Framework (OSF) repository. More information in the Introductory class below. The name is hydraulic construction. Actually it covers the hydraulic design of a storm water management system and the hydraulic design of an Aqueduct. With hydraulic design, I mean that the class teach how to calculate the hydraulics of infrastructure. It will not teach anything else and neither will cover how to really draw them to produce a final executive project. These knowledges are communicated in the class called "Progetto di Costruzioni Idrauliche".

Tools

During the class I will introduce sever tools for calculations.

Open Science Framework (OSF): It is a tool for sharing a workflow, especially design for scientific purposes. It allows storage of files and documents and their selective publication on the web.
Python - Python is a modern programming languages. It will be used for data treatment, estimation of the idf curves of precipitation, some hydraulic calculation and data visualisation. I will use Python mostly as a scripting language to bind and using existing tools.
SWMM - Is an acronym for Storm Water Management System. Essentially it is a model for the estimation of runoff adjusted to Urban environment. I do not endorse very much its hydrology.

La teoria dell'idrogramma Istantaneo Unitario

L'idrogramma instantaneo unitario è una teoria semplificata dell'aggregazione e propagazione dei deflussi. Ecco nel seguito, le mie lezioni (per il corso di Costruzioni Idrauliche per Ingegneri Civili a Trento). In 2016 I restructured it in parts, and according to new pieces of theory that I developed with Marialaura Bancheri and finding new inspiration form works by Gianluca Botter, Enrico Bertuzzo and Andrea Rinaldo on travel times. A good review is certainly Rigon et al., 2015. Unfortunetely slides are (so far) in Italian.
