Oh yeah rivers can have beaches. Look up river sand bars. I am from the South Eastern USA, specifically Georgia in the inland costal plain. Over the eons, the vast majority of this area was formed from the erosion of the Appalachian mountains. The beach front was moved farther out as the land lifted and mountain sediment, etc accumulated to our current coastlines. The rivers have cut into and exposed old beach sandbars. These areas erode the old fish poop sand down river and they collect in river bends. I have seen water wells being dug and hit the old beach layer about 200 feet deep (over 50 miles from the coast) and pull up old seashells by the hand full.
