Vampiric Blood River
We've all heard about a river of blood. But what would happen if we had an actual river of blood? Say a band of vampires creates a magical portal that draws blood from all the people in the area and combines it into a continually flowing river. The river starts in an old, dry riverbed and the blood flow is roughly equal to the previous water flow. Because the blood is pulled from many people, it will be full of different blood types, but to avoid any weird immune system reactions, the magic filters out the immune system.
What would happen? What kind of plants or crops, if any could grow along this river. What kind of microbes? Would it flow? Can vampires use it for nutrients or would the river get clogged and full of microbes and algae too quickly?
Bonus questions, what would happen if immune cells were included in the river?
