The pressure at the bottom of a column of water occurs because of the weight of water. A cubic foot of water weighs about 62.4 pounds. The bottom has a surface area of 144 square inches. This means that every square inch feels 62.4/144 pounds, or we say ,434 pounds per square inch. Pile another foot of water on the first, and the pressure doubles.
It takes 2.31 feet of elevation to add an additional pound per square inch.
The pressure is independent of the area of te column. A one-inch pipe 50 feet tall has the same pressure at the bottom as a 50 foot tall huge tank.

It depends. Is it open channel flow, like a sewer, or pressurized?
