Tropical (Equatorial) Rain Forest
(TRF)
Conditions
Constraints vs. Opportunities
What are the locational
characteristics of TRF?
• at equator
• around 5 degrees north or south
• occasionally extends to 20 degrees
Atmospheric Conditions
• Heavy precipitation
(around
3000mm/year)
• convectional
rainfall
• high temperature
• lack of seasonality
• small annual range
of temperature
Hydrospheric Conditions
• Large discharge and large baseflow
• Large underground flow
Soil
• Oxisol
• fine texture Why?
Answer: chemical weathering
• infertile and slightly acidic Why?
Answer: Precipitation > Evaporation
• heavy leaching Why?
Answer: Precipitation > Evaporation
• hard pan
Opportunities in TRF
Favourable climate Suitable for plant
growth and farming
Luxuriant hard
Suitable for
woods
building and
making furniture
High species
Rich gene pool
diversity
which is good for
food and
medication
Oxisols are
Rich in iron and
common
aluminum which is
good for mining
Constraints in TRF
Too hot and too humid Unfavourable working
conditions
Spread of insects,
bacteria and diseases
Silting
Hinders navigation
and construction of
HEP stations
Dense vegetation
Reduce accessibility
Not pure stands
Infertile soil
Not good for
lumbering
Not favourable for
plant growth
