Yes, water follows the curvature of the earth. This is why, at large distances over water you will see ships disappear over the horizon or only see a portion of very distant tall structures, wind farms, etc. This is something you can see yourself on a clear day on the beach. It's not "mirages" or "dense air".
Earth's curvature from high altitude
This photo was taken at 23 km high from a weather balloon. Flat-earthers will attempt to explain this away as a "lens distortion", or "fish eye view" or photoshop or whatever. The below was taken by a guy on Concorde at 58,000 feet.
The reason I am posting these is because it's possible to send up a camera and a weather balloon for as cheap as 150 quid and some approval. Flat-earthers can do this themselves.
The distance to the horizon is just over 3 miles
At 3 miles (5km) the curvature is 1.96 meters, yeah you aren't going to see much difference.
On any "flat earth model" Australia and South America are as far away as you can get. You would have to fly an absurd distance (over land) to get to the two.
But the world isn't flat, which is why you can fly between South America and Australia, over water, and prove it to yourself.
As a flat-earther, you are going to demand people "prove it to you". You are surrounded by proof, satellites, GPS, images/footage, science, basic common sense, etc, if you are going to reject all that, then you will reject anything posted here that's for sure.
My point is that you can prove it to yourself. You can watch ships disappear over the horizon on a sunny day at the beach, you can do the canal experiment with a friend, you could even catch a plane from Chile to Sydney. Entirely up to you.

If it were linear wouldn't disappear. You would be 100s of KM to the horizon. The horizon alone proves flat earther are retarded.
To correct you its actually 8" per mile squared
That incorrect. The drop 1km past the horizon is 8cm. The rate of drop increases with distance, as well its a curve. FYI mile squared is a unit of area not distance.
Focus on Kish Bank lighthouse and you should see curvature to the left & right
You can see it. It's incredibaby subtle, you'd need precise equipment to measure it. The higher you go the more pronounced it gets.
Here's a still from a weather balloon at over 114k feet. You can see the curve.
More damning is that Kish Bank lighthouse is approx 7 miles from Dublin Bay and according to the earth curve calculator should be approx 1/3 hidden by the curve
You can see to the horizon. So the obscured parts are based on distance past the horizon. At sea level, the bottom 2.8m is obscured not 1/3 of it (10m). Here's a calculator, as you'l no doubt insist on proof. https://www.omnicalculator.com/physics/earth-curvature
Of course, if you looking at if from lad, you're probably not at sea level. If you sat 10m+ above sea level you can see all the way to the lighthouse. This is primary school stuff.
