3. Facts:
• The Basin represents only 30% of
Thailand’s area BUT is the basis for
almost 70 % of the nation’s economy.
• More than half of the entire Thai
population live in the Chao Phraya River
basin region- that is mostly in cities along
the river system.

4. Bangkok: Thailand’s Mega City

5. • In the past: Cities develop naturally
1. As more people migrate to the city
markets were set-up
neighborhood become established
cities grew outward away from the
center

6. The Establishment of Bangkok
- is due to the relationship between the
physical geography and human activity

7. Physical Geography: the landscape
Needs for Defense: usually enemies would
attack from water
Location of Resources: such as water,
farmland, sources of energy.

8. Urban Planning
- The growth of Bangkok needs to be
planned and regulated.
- As cities expand, they take more lands.
Bangkok is located within the river basin
(rich farmland), without control, valuable
farmlands would be taken over to
accommodate the expansion of the city.
- The Department of Public Works and Town
and Country Planning is responsible for this

15. Urban Issues in Chao Phraya
1. Sanitation
- Disposal of human
waste and
household garbage
go directly into the
river.
 Some homes were torn
down
 Residents find new
housing
 Cannot rebuild once
damaged or destroyed
by storms

16. Industrialization
• Industry uses great
quantities of water
and creates material
wastes that are
harmful to the
environment
-Chemicals and heavy
metals are disposed
in soil, they are
carried with rainwater
to the river
• - Health risk for
humans , aquatic and
animal species in or
around the river

17. • Government impose
strict regulations upon
industrial expansion
• Monitor water quality
of the river

18. Water Use: Flood Control and
Hydro electric Dams
• Flood Control
 Flood prevents
damage of property
 Silt that nourishes
the soil is reduced
- Farmers will then use
fertilizers to the soil
- Chemicals harm
environment

19. • Dams
• Construction to
generate energy and
meet energy needs of
big cities.
• Dams alter flow of run
off downstream
• Farmers depends on
irrigation system
• Crops become more
expensive
