If the greatest velocity of the San Juan river in December 9 was 20 centimeters per second what was the approximate diameter of the largest particles that the river could have carried?

The maximum particle size that a river can carry is often estimated using the velocity of the water. According to the general rule of thumb, for a flow velocity of 20 centimeters per second, the largest particles that could be transported are approximately 2 to 3 millimeters in diameter. This estimation can vary based on factors like water density, sediment type, and flow conditions.
