The cut
1,613 metres, to scale.
A slice through Cehennem Deresi Canyon where it is deepest and narrowest, measured on the Copernicus relief model every 30 m. Same scale as the landmark standing on the floor.
Standing on the floor, to scale: Eiffel Tower · 330 m · Burj Khalifa · 828 m
Depth is measured to the lower rim; the width is from rim to rim. A 30 m relief model smooths the narrowest walls, so a slot canyon reads shallower than it is.

The river
The Berta Çayı runs highest from March to April.
The Berta Çayı carries about 8.9 m³/s on average here. It runs highest from March to April, fed by melting snow.

From about 3.2 m³/s in the lowest month to 34 m³/s in the highest. Its basin above this point covers 584 km².
Estimate: long-term flow from the HydroATLAS model (WaterGAP, 1971–2000) shaped by the monthly rain, snow and temperature of the area (NASA POWER). Dams change it. Not a forecast.

Recent years
Wet years, dry years.
Rain of each month as a share of the 1991–2020 average. A dry year means a lower river and hotter rock; a wet one, more water in the gorge.
