Useful handbooks and resources for EPANET 2

Useful handbooks and resources for EPANET 2

Looking for a good tutorial to start the study of EPANET 2.0, a public domain hydraulic analysis package for water supply networks, I was impressed for the high quality and origin of most of the documents that I found on Internet. Even more for the resources developed thanks to its toolkit. So I have collected the most interesting ones from my point of view.

Pipe network analysis with open source software: PVnet and EPANET

Pipe network analysis with open source software: EPANET and PVNET

Recently I have read that a local municipality has finally unblocked an old urban regeneration project in which I worked for many aspects. One of these was the pipe network analysis for that disused area. Fortunately I used PVnet and the job was simple. In this article I introduce this open source software and EPANET2, because its computational engine is used by the first one and it is more complete and powerful. Besides I show you that they can be installed in a Linux system using Wine. 

Storm sewer webapp: concept

Storm sewer webapp: concept

I will describe elements characterizing step by step the conversion of my storm sewer program into a web application fully available within any modern browser. It will also be equipped by a convenient graphical interface and by the powerful new features. Here I will insert the progress of works that will lead to the final release of this webapp.

Horizontal grit chamber checking software

Horizontal grit chamber checking software

Simple programm written in a QuickBasic language and compiled in FreeBASIC, which allows you to verify an horizontal grit chamber. Once you have put the geometric section and the incoming flow, it computes using elementary formulation the shorter length of this hydraulic device.

A spreadsheet to set detention basin volume

A spreadsheet to set detention basin volume

I post a simple spreadsheet to determine the volume of a detention basin, following the guidelines for the evaluation of hydraulic compatibility pubblished afterwards the OPCM 3261/2007 (Ordinance of the Prime Minister). They are written to help the practice of hydraulic invariance and the professionist into choice the design of works that change the land use.

Storm_sewer_0_9_3 released!

Update of my software to design a storm sewer system

Update of my software to design a storm sewer system, in this version it is possible a more realistic schematization of the system and is fully compatible with Linux. I have added a further degree of relationship, reducing to zero the subdivision and the joining part by part of the system. Besides it produces a backup copy of the input data, so it is possible to change and analyze again the sewer.

Design a storm sewer fixing speed

Tutorial for design a sewer, setting speed and using the program storm_sewer.exe

In this tutorial I will show you how to use my program, storm_sewer.exe, in order to design a system, fixing the speed line by line. The sewer data are taken by a duplicated lecture note, so you will able to compare my results with these. Besides I prove how a complex system could be subdivided for a better compatibility with my software.

Software to design a storm sewer system

Open source software to design a storm sewer system

I publish an open source code that calculates line by line the suitable diameter for a given sewer system, using the linear reservoir model. It can design according to three different variables: speed, shear stress or slope of the line. It gives a final report, useful for calculus relations or following elaborations.
