Amazon River (specific statistics on the length, depth)?

Question

length, depth,

Answer 1

depending upon who you talk to, is anywhere between 6,259km/3,903mi and 6,712km/4,195mi long.

The total length of the Amazon River from its source springs in the Andes (taking the Ucayali River as the continuation of the main river into the Andes), is estimated at 6518 km (not including all river bends, and measured the short distance around Marajó Island in the mouth of the Amazon), or ~4075 miles in length. This is exceeded only by the Nile River (including the Kagera River) of Africa with a total length of 6671 km (4170 miles). The headwaters are located high in the Andes at an elevation of about 5,200 meters (17,000 feet), and only 190 kilometers (120 miles) from the Pacific Ocean.

The width of the Amazon at Iquitos, Peru (3,600 km/2,250 miles from the ocean) is about 2 km. Ocean-going ships can easily access the Port of Iquitos at high water, as the mean depth of the current-canal of the Amazon is between 40 and 50 m (or up to 150+ feet deep), and in places, over 100 m (over 300 feet) deep. Even hundreds of miles away from the ocean, sections of the bottom of the river channel actually lie below sea level!

in one second the Amazon pours almost 60 million gallons, or 620,000 cubic yards of water, into the Atlantic Ocean

The Amazon is the widest river in the world. In land from the mouth of the river there are portions of the river that are almost 5 miles wide.  This impressive width expands to almost 15 miles during the flooded season.
