Portuguese term

espelhos dos tuneis

Portuguese to English Tech/Engineering Construction / Civil Engineering Damn construction
I keep seeing this term `espelho` mentioned in this report on problems with erosion in the spillways, they talk about `os espelhos do vertedouro`, and in the below context also.
Is this something to do with surface of the spillway chute, tunnels or water level/surface?



Finalmente pode se sugerir que o uso continuado do vertedouro devera ocasionar uma erosão mais rápida no canto esquerdo hidráulico entre os espelhos dos tuneis e a parede da bacia de dissipação

O termo espelho, neste caso, assim como "espeleologia" (estudo de cavernas), vem do latim 'spelaeum", que significa cavidade, poço, túnel...
