In addition to the Mississippi River, which other river flows from north to south into the Gulf of Mexico?

On the more detailed maps of the United States, you can often see that there are two rivers east of the Mississippi River that flow into the Gulf of Mexico from north to south.

The one on the west side is called The Alabama River, the one on the east side is called the Chattahoochee River

The Grand River already flows into the Gulf of Mexico at an angle of nearly 45 degrees. On its east side, at the position of X in the picture, there are two relatively Famous rivers, one is the Colorado River and the other is the Brazos River.

Of course, there are many other smaller rivers.
