Physical Factors For Dam Consideration Flashcards
(6 cards)
1
Q
Solid…
A
solid foundation to support large water volumes. Not on earthquake fault line = collapse
2
Q
Impermeable/non porous rock…
A
Prevents seepage from the dam, ideally crystalline granite
3
Q
Narrow valley
A
additional strength, lowers construction costs
4
Q
Climate
A
cool climate, less surface evaporation, large precipitation rates ideal
5
Q
Sufficient catchment potential
A
Large river basin = greater catchment area. Need of snow melt or rain to feed resevoir
6
Q
Deep valley
A
Allow deep lake to contain flood water, smaller area reduces surface evaporation
