What is Civilization?
• For civilization to emerge you need
– Agriculture
– Cities
– “Leisure time” to develop skilled workers
• Among the key features are
– Ability to manage water
– Suitable soil and climate for agriculture
Pacific Northwest Exception
Due to rich salmon runs
Managing Water Resources
• Even in the earliest civilizations we can
find evidence of water management
– Delivery of drinking water to cities using
qanats and aqueducts
– Routing of wastewater out of cities
– Delivery of water for agriculture through
irrigation
– Transportation
– Hydropower
Drinking Water for Early
Civilizations
• Earliest civilization centers emerged in:
– Mesopotamia along the Tigris and Euphrates
Rivers (Syria and Iraq)
– Indus River (Pakistan)
– Yangtze River (China)
– Nile River (Egypt)
– Greek and Roman empires (Mediterranean)
Figure 1.1
Qanats
• Qanat system developed in Mesopotamia
area
– From a Semitic word meaning “to dig”
– Semitic: subfamily of Afro-Asiatic language
family that includes Hebrew and Arabic
• Delivered ground water by gravity from an
upland area where it was plentiful to
lowland agricultural areas and cities
• Qanat shafts served 3
purposes
– Air supply
– Remove soil and rock
– Keep tunnels from being
too long

Aqueducts
• Roman empire developed an extensive
system of aqueducts to deliver surface
water by gravity to cities
• Water was delivered to fountains and
baths where citizens collected and used it
• Allowed cities to grow in size
• Reduced amount of time that individuals
(usually women) spent obtaining daily
water

Drinking Water Today
• Supplying water and removing wastewater
is still an important function today
• Many problems
– Water quality (bacteria, carcinogens, heavy
metals, nutrients etc.)
– Water quantity (competition with agricultural
for water)
• Discuss these in later chapters

Drinking Water for Early Civilizations
Early Irrigation and Flood-Control Projects
Early Water Transportation Development
Early Hydropower Development
Early Irrigation and Flood Control
• Civilization centers developed where soils
were fertile
• For soils to be fertile nutrients must be
collected and deposited in an area so that
they become concentrated
– Flooding deposits rich mountain (volcanic)
soils in river floodplains
– Glaciers deposit rich topsoils at their terminus
and in wind blown loess
Early Irrigation and Flood Control
• Floodplains are often in dry areas that
require irrigation
• Nile River civilization is a good example
– Sediments from the mountains of Ethiopia
and Sudan are deposited in the floodplains of
Egypt
– Ancient Egyptians developed an elaborate
irrigation system for Nile floodplain
From Chapter 3
Simple devices for lifting water from the river into irrigation canals:
shadoufs, tambour or Achimedes screw, and saqia water wheel
Early Irrigation in the U.S.
• Anasazi Indians developed irrigation
systems in Southwest desert region
around 950 AD
Early Irrigation in the U.S.
• Brigham Young and Mormon followers began
extensive irrigation system in Salt Lake Valley of
Utah in 1847
• Region receives 15 in of annual rainfall
• Constructed diversion dams across rivers and
diverted water into irrigation ditches
– Small diversion dams were made of logs, rocks and
brush
– Irrigation ditches were made using horse-drawn plows
and hand digging
Early Irrigation in the U.S.
• Construction of an irrigation ditch was not
simple
– A ditch too steep would cause fast flow that
would erode the ditch and wash it out
– A ditch that was too flat would not move water
• Rule of thumb was a fall of about 2 feet
per mile
Early Irrigation in the U.S.
• Homestead Act passed in 1862
– Opened the floodgates of development in the
West
– Anyone over the age of 21 could acquire
ownership of 160 acres if
• Lived on it for 5 years
• Made improvements to the property
– Cost was $1.25 per acre
• Water for irrigation became a critical issue
Sears, Roebuck & Co. sold windmills to pump groundwater
Early Irrigation in the U.S.
• In 1870’s Horace Greeley, editor of NY
Tribune promoted settlement in the West
with the phrase “Go West, Young Man”
• Time was ripe for western migration
– Civil War ended in 1865
– Transcontinental railroad completed in 1869
• Organized a settlement in Colorado (today
called Greeley) to replicate the irrigation
successes of Mormons in Utah
Early Irrigation in the U.S.
• Late 1800’s was a period of unusually wet
weather in West
• As normal rainfall returned many settlers without
irrigation water were forced to abandon their
land and move into town to work in other
professions
• Drought period in 1930’s forced more settlers to
abandon land and become migrant workers
– Described in “Grapes of Wrath” by John Steinbeck
– Ken Burns “Dustbowl” on PBS

Irrigation Today
• Irrigation today is extensive in western
U.S. and other areas of the world
• A number of associated problems
– Competition for water with urban sources
– Salinization of soils
– Sedimentation of reservoirs
– Effect on stream flow and water quality
• Discuss these in later chapters

Drinking Water for Early Civilizations
Early Irrigation and Flood-Control Projects
Early Water Transportation Development
Early Hydropower Development
Early Transportation Development
• One of the reasons civilization centers
developed near rivers is these were the
“interstates”
• River and canal systems used for boat
traffic
• Nile and Yangtze River are examples
• Later extensive canal system developed in
Europe
Felucca on the Nile in Egypt
Early Transportation Development
• Erie Canal constructed 1817-1825
– Connected Buffalo on Lake Erie to Albany on
Hudson River
– 363 miles
– Cut travel time from 20 days to 6 days
– Cut transportation costs from $100 to $5/ton
• Ohio & Erie Canal connected Ohio River
to Lake Erie

Early Transportation Development
• Mississippi River has been through history
and continues to be a major transportation
system for U.S.
• Before steamboats keelboats and flatboats
were used to move produce down river
• After steamboats developed (1810) traffic
ran up and downstream
• Army Corps of Engineers responsible for
clearing snags
Jolly Flatboat men, George Caleb Bingham
Water Transport Today
• Water transportation not as critical today due to
rail and trucking industries
• Still a source of conflict
– Navigational needs vs. urban and agricultural use of
water
– In 2003 Corp of Engineers released water from Lake
Lanier and lower lakes on Chattahooche to float
barge traffic at Columbus
– Later that year drought conditions caused record low
lake levels
• We’ll discuss this in later chapters

Drinking Water for Early Civilizations
Early Irrigation and Flood-Control Projects
Early Water Transportation Development
Early Hydropower Development
Early Hydropower Development
• Water wheels were used to grind grain as early
as 100 BC in Greece
• Until the time of steam engines, water mills were
a major source of energy
• By 1800 there were 500,000 water mills in
Europe
• Mills ground corn and wheat, powered bellows
and hammers to make iron, ground ingredients
for paper, cut wood, and powered textile mills

Early Hydropower Development
• With the invention of the light bulb by Thomas
Edison in 1879 hydropower began to be used to
generate electricity
• One of the first generating plants was built at
Niagara Falls to supply electricity to Buffalo NY
– Designed by George Westinghouse
• Hydropower production peaked in the 1940’s
when it provided 1/3 of electricity consumed in
U.S.

Hydropower Today
• Hydropower is still important but ability to
transmit electricity is making some dams
less critical
• Movement to remove dams in some cases
• Focus on environmental impact of dams
on fish such as salmon
• We’ll discuss this in later chapters
Chapter 1 Summary
• Management of water resources has been
a hallmark of civilizations throughout
history
• Water managed to provide drinking water,
irrigation, flood control, navigation, and
power
• Although we’ve been managing water for
centuries, many old and new problems
now confront us
