Thank you for your kind visit and feedback.
Your comment on the horizon is noted with thanks.
For this river, measurements indicate that its velocity flow is about 4.5meters/second which translates roughly to 15km/hr.
For a mountain slope, or a water fall, there is always a gradient, and similarly for a river of fast flow, a hydralic gradient is a matter of fact.
Unlike the sea or huge lake, where water is not flowing on a gradient, the horizon is clear cut and is ALWAYS level.
You are right to say a horizon is level.
Whereas for a river, it is not a horizon, it is what we will call in terminology a 'profile', either longitudinally or transversely.
I was told by one photographer that he would find this fact out and let me know if there is any other facts to show a 'horizon' for a river, and so far, after 3 months, I am still waiting for him to give the feedback.
Your gallery has great photos and I like particularly 'Relax' your landscape shot. Hoping to share more photography with you.
Thank you for your feedback, Renaud, once again.
