This book shows you how to use a GPS and Google Earth to create
simple and expressive maps to share on the web like the one shown
on the cover. With a reading time of a mere 10 hours you will learn
to work with a GPS without making mistakes, to use it with Google
Earth including in areas without internet access and to quickly
create diverse interactive maps that other people can see and
modify over the internet without the need for experts or
unnecessary complications. Even though it has been written in the
context of Relief and Development work, the same process is valid
for whatever other application.
Generators are an essential part of many projects and give rise to
a very significant expenditure. This book introduces you to them
from the management perspective. It is not about turning you into
an electrician or a mechanic but about choosing the most suitable
generator for your project and running it in the most economical
way possible. You will learn how to improve existing installations,
determine the power required, make informed choices between the
different available options, oversee key aspects of the
installation and avoid wasting energy that compromises the
sustainability of the projects.
This manual aims at walking the reader through the design of a
water supply network in a Development context by explaining in a
simple manner how to build and analyze a computer model of a water
network with Epanet. Epanet is a free and widely used software from
the U.S Environmental Protection Agency that models the hydraulic
and water quality behavior of water distribution piping systems
Arnalich Water and Habitat is an organization that helps improve
the impact of humanitarian actors through training and consultancy
in the fields of Water Supply and Environmental Engineering.
This collection of exercises has over 320 images designed to walk
you step-by-step towards the modeling of water distribution systems
which are commonly found in development work. You will learn how to
load cartography and background images; to determine water demand
and spatial allocation; to simulate the evolution of water quality
in networks and to make economic comparisons, while avoiding the
most common costly mistakes. This manual will help you make
informed decisions for achieving clear and measurable results in
development projects interventions. Epanet is a free and widely
used software from the U.S Environmental Protection Agency that
models the hydraulic and water quality behavior of water
distribution piping systems.
Tackling a Gravity Flow Water Project for the first time? This book
is intended to get you on your feet quickly. You'll learn how to
select pipe sizes, work out the demand you need to meet, interpret
topographic surveys and perform economic calculations to compare
different alternatives. Besides producing a sound design, it will
help you to get to grips with the materials, put in orders,
supervise the building work, and most of what you will need in your
quest for access to safe water.
This book will provide you with the tools for designing drinking
water systems and doing the calculations by hand. With minimal
theory and through 28 progressive exercises, the most common
scenarios are introduced one by one: branch lines, joining multiple
sources, valley passes, pressure zones and even looped systems. You
will learn how to decide on pipe diameters, check an existing
design or plan a system enlargement, following simple, quick and
reliable guidelines to achieve clear and tangible results for
gravity flow water projects.
En este manual se explican de manera sencilla y amena los aspectos
basicos para disenar una red de abastecimiento de agua con Epanet y
se discuten muchas cuestiones relacionadas para llevar los
proyectos a buen puerto. Se pretende que con su lectura, seas capaz
de disenar las redes mas comunes en Cooperacion al Desarrollo,
tomar decisiones informadas y obtener resultados claros en las
intervenciones."
Los generadores son una parte imprescindible de muchos proyectos a
la vez que generan unos gastos muy importantes. Este libro te
introduce en ellos desde la perspectiva de la gestion. No se trata
de hacerte instalador electricista o mecanico, sino de elegir el
generador mas conveniente para tu proyecto y hacerlo funcionar de
una manera lo mas economica posible. Aprenderas a mejorar
instalaciones existentes, determinar la potencia necesaria, elegir
de manera informada entre las distintas opciones disponibles,
supervisar los aspectos claves de la instalacion y a evitar
derroches de energia que comprometan la sostenibilidad de los
proyectos."
Este libro pretende ponerte en pie rapidamente. Aprenderas a
seleccionar tuberaas, averiguar la demanda a satisfacer,
interpretar estudios topograficos o hacer calculos economicos para
comparar alternativas. Te ayudara a familiarizarte con los
materiales y realizar pedidos, comprender la funcion y las
posibilidades de los distintos componentes y dimensionarlos,
supervisar los elementos fundamentales de la obra sin olvidar el
calculo hidraulico para que el agua llegue a todos los puntos con
la presion deseada."
Este libro te muestra como usar un GPS y Google Earth para crear
mapas sencillos y expresivos como el que se muestra en la portada
para compartir en la red. Con una lectura de apenas 10 horas,
aprenderas a trabajar con un GPS sin errores, a usarlo junto con
Google Earth incluso en zonas sin acceso a internet y a crear
rapidamente diversos mapas interactivos que otras personas pueden
ver y modificar a traves de internet sin necesidad de expertos ni
complicaciones innecesarias. Aunque se plantea en el contexto de la
Cooperacion al Desarrollo, el mismo procedimiento es valido para
cualquier otra aplicacion.
Esta coleccion de ejercicios comentados y resueltos paso a paso en
mas de 320 imagenes, te introducira progresivamente en el calculo
de las redes de agua mas frecuentes en Cooperacion al Desarrollo.
Aprenderas a incorporar cartografia, determinar la demanda y
localizarla en el espacio, simular la evolucion de la calidad del
agua y comparar economicamente distintas alternativas evitando los
errores de diseno mas frecuentes.
En apenas 4 horas de lectura podras decidir sobre la viabilidad del
sondeo, seleccionar la bomba y generador necesarios, familiarizarte
con la funcion y las posibilidades de los distintos componentes,
realizar pedidos de material con precision y supervisar los
elementos fundamentales de una instalacion. Todo ello explicado de
forma sencilla, practica y cronologica.
Con la minima teoria y a traves de 28 ejercicios progresivos, se
van introduciendo poco a poco las situaciones mas frecuentes:
ramificaciones, union de fuentes, paso de valles, zonas de presion
e incluso el calculo de mallas. Aprenderas a determinar el diametro
de tuberias, comprobar algun diseno existente o planificar una
ampliacion de una manera sencilla, rapida y fiable, para lograr
resultados claros en los proyectos de agua por gravedad
