Which scenario is most likely to reduce thermal pollution without changing plant operations?
A
Discharge into a small, slow-moving stream during drought; lower dilution increases thermal impacts even if operations stay constant.
B
Discharge during higher river flow periods, increasing dilution and heat capacity; temperature rise at the compliance point decreases.
C
Remove riparian shading to increase sunlight; more solar energy reduces the relative effect of the discharge temperature difference.
D
Channelize the river to reduce residence time; slower mixing increases the thermal plume persistence and intensifies warming.
