I generally refer to it as placer deposits but they are alluvial meaning sediment. Gold is very resistant to being weathered. When crushed it is maleable. So when rocks are ground up in the processes of erosion, gold retains its mass. It is very heavy and so falls downward. It tends to get concentrated in traps that can be eddies behing boulders, cracks, etc. It tends to travel in a straight line in the stream channels. These properties make it easier to find and extract in rivers.

Gold found in rivers is called alluvial gold.
It is washed out of gold veins and carried along on the river bed..
It isn't necessarily found near water,it could be anywhere.
The gold in rivers is the stuff you see the old prospectors panning for.
People still do it but it's not as popular as it used to be.

Because it actually found in rocks that are eroded by water and being very heavy, everything else is washed away, leaving the gold sitting in the creek bed, just like flakes of gold are found in a miner's pan. Most gold is actually dug out of the ground.

1- due to river carry away soil and dissolve the other element
and the gold can not dissolve un water
2- some people die in sunk ship or boat with his gold

The matrix of the rock erodes and leaves the gold. It is known as alluvial deposits because the sedimentary host rock decades over time.

Because the water that carries the gold has eroded the rock in which it was "trapped"

Small amounts of gold are actually dissolved into seawater, as well...
