Water Resources
Hydrology- study of water
Freshwater Pollution
Point Source Pollutionpollution that comes from a
specific location
Ex. A leaking landfill
Nonpoint pollution is
pollution that does not
have a specific point of
origin.
– Ex. Runoff-can carry
waste oil from streets,
wash sediment from
construction.
– Carries water from
fertilizer, pesticides,
animal feed lots.
Stream flow
The ability of a stream to erode and
transport materials depends largely on
velocity.
Discharge- The volume of water flowing past
a certain point in a given unit of time.
Gradient is the slope or steepness of
a stream channel.
Gradientmeandering
Tributary- a stream that empties into
another stream
Laws to protect our environment
Montreal Protocol -Treaty to ban the use of ozone
depleting chemicals
Kyoto Protocol- International Agreement to help regulate
climate change
International Panel on Climate Change- group who
meets to discuss possible solutions to climate change.
International Whaling Commission- Set regulations and
bans on killing whales.
Convention of Trade of Endangered Species- Treaty
which helps regulate the trading and selling of endangered
species.
Erosion
Streams generally
erode their channels
lifting particles by
abrasion, grinding, and
by dissolving.
Beach erosion occurs
because of wind and
waves and human
urbanization.
