Water supply systems and Stormwater management infrastructures 2017

This year I decide to renovate the teaching of my class of "Hydraulic Constructions".  Usually, under this name, one thinks to dams, levees, or other infrastructures. In fact, what I will  teach is how to design a water supply system for a city or for a city district, and how to design the infrastructures for storm water management.

This the foreseen schedule of the course. L Means a laboratory class, where the students are asked to calculate, think or project something. Actually it will be that I will do stuff for them, introducing some tools and asking them to repeat and complete the task on their dataset. Tentatively, it will be a "learning by doing approach" which I used also the last years but to a minor extent. 


I have 60 hours in total over thirteen weeks. So the schedule could be the following one

Storm waters
  1. T - Introductory Class
  2. T - Statistical properties of ground precipitations. Mechanisms  of formation of precipitation. Ground based statistics. Extreme precipitations.  
  3. L - Explorative data analysis. Investigating data with Python (or R).  
  4. T - Extreme precipitations. Around the concept of return period. Extreme distributions. 
  5. L - Estimation of Extreme distributions with Python (or R)
  6. T - Element for the design of storm water management infrastructures.  
  7. L - Short introduction to QGIS for representing urban infrastructures. 
    1. T - Element for the design of storm water management infrastructures. - II 
      • L - Simple estimations of the maximum discharge via Python
      • T - Pumping stormwaters.
      • L - Designing some part of a sewer network with SWMM and Python. 
      Clean water supply - Aqueducts

      As a  general, simple and descriptive reference, the first six chapters of Maurizio Leopardi's book can be useful :
      Here the class lectures:
      1. T - Aqueducts in 2020
      2. L - Introduction to EPANET (and related GIS)(YouTube2017)
      3. T - Aqueducts' distribution networks: the water demand and some design indications)
      4. T - External aqueducts
      5. T - Introduction to intakes  for water supply
      6. T - Water uptakes
      7. L - Reservoirs
      8. L - Design and verification of distribution networks with EPANET - 
      9. T - Houses' infrastructures
      10. T - Urban Drainage Systems
      11. L - Design and verification of distribution networks with EPANET - I I (YouTube on Water Demand)
      Tools

      During the class I will introduce sever tools for calculations. 
      • 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. 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. 
      • LaTeX: il sistema per la scrittura e la composizione di testi matematici ed ingegneristici. Il testo di Lorenzo Pantieri e Tommaso Gordini è un piccolo gioiello

      EPAs for water

      EPA, in this case, stands for Environmental Protection Agency (of the United States).
      We use a couple of models developed there, especially in my class of Hydraulic Constructions.
      These products are:


      and they are available as open source.



      There is  an organization of people gathering who are interested in working on them.  You can join them at:


      I do not endorse them as the best models ever. But they are there, opens source, and have a community. I see them as a starting point for injecting new ideas and extensions.

      uDig Jgrasstools resources for urban hydrology, culverts and water supply systems design (in Italian)

      Ho sempre pensato che affrontare i problemi del dimensionamento di un acquedotto e di una fognatura pluviale, potesse essere semplificato dall'uso di un GIS. L'idea, naturalmente, non l'ho avuta da solo, ma  ragionando assieme ad altri, in particolari, i miei ex-allievi di Hydrologis e di Hydromates e i colleghi Paolo Bertola e Maurizio Righetti. Hydrologis and Hydromates, già per conto loro, avevano provveduto ad implementare in uDig i nettools, una serie di strumenti che consentono l'accesso al software Epanet per la verifica delle reti in pressione. In parallelo, ho chiesto la loro collaborazione per portare il mio software di calcolo delle fognature pluviali Trento_p, nello stesso sistema.
      Con l'ulteriore aiuto di Federico De Col, Leonardo Perathoner e di Bilal Adem Esmail (sempre supportati da Hydromates)   ho poi lavorato per documentare il tutto.

      Ora uso il tutto nel mio corso per la laurea magistrale di Ingegneria Civile: quest'anno, per la prima volta.  Ecco dunque la documentazione che serve:
      Per quanto riguarda l'utilizzo dei Nettools (Epanet) si può fare riferimento:
      Per quanto riguarda Trento_p abbiamo implementato il tutorial che si può trovare qui. Le slides delle lezioni, mirate a Trento_p, si possono trovare qui di seguito:

      Naturalmente può essere utile dare un'occhiata alla documentazione del vecchio Trento_p
      Caricheremo, con l'avanzare del corso nuovo materiale. Tenete d'occhio la pagina!
