Estimation of water velocity in a video using Mathematica

Hi,

Today morning I measured the velocity of river flow by velocimeter and it was 1.15 m/s.

For studying the ability of the Mathematica in video file processing, I took a 60-second video from the water surface with a smartphone. I attached herewith the video file.

Is it possible to estimate this important parameter in this video using the Mathematica?

Although, two years ago, we did a study for estimating water suspended sediment in a laboratory flume, based on image processing (NOT VIDEO). We got the expected results and it was excellent.enter image description here enter image description here

Thank you for your help.

Alec,

I took a 60 seconds high-quality video from another river. The surface water velocity is 1.66 m/s. It may be better for video analysis. Please see the enclosed video.

Alec,

You did a good job. This is a very important issue in water engineering.

In the lab, I measured the velocity of water for 20 velocities e.g. 0, 0.264, 0.444,......, and 0.607 m/s. I enclosed only a sample of videos. It may be helpful in achieving the expected results. enter image description here

Dear Alec,

You did a great job. Thank you so much for your effort. Estimating water velocity with the camera/smartphone is very important. I will take a high-quality video from water surfaces in specific dimensions and try some things. I will definitely let you know if I find a solution.

I really really appreciate your help.
