If the lower stage of the river ebbs and flows with tides, and the uppers stage flows downhill with gravity...

Question

then is there a point in time in the middle stage of the river where the river flowing in the way from high tide and the water flowing out the way from the gravity meets??

When the ocean is approaching high tide, the water in the lowest area of the river, closest to the ocean, flows IN.yes?but the rest of the river from the mountain is flowing OUT.is there whirlpools or something where the 2 meet?

Answer 1

Your question is a little confusing to me. I will try to explain to you what I know. At low tide the river flows to the ocean. At high tide the ocean rises and sends its water up the river. The river flow is blocked and rises as the ocean does . The river cannot rise any higher than the ocean and above this point the river is still flowing as usual. Hope I made myself clear.

Answer 2

THE TIDE OF THE OCEAN AND THE FLOW OF A RIVER MEET, BUT BECAUSE THE RIVER IS ABOVE SEA LEVEL, EXCEPT AT ITS END, THE FLOW CONTINUES AT THE SAME RATE UNTIL IT BECOMES PART OF THE OCEAN.
