Hi, i trying to solve a task from my school. I doing a watershed and are going to use multiple pour point to find out from were a toxic sample has its origin from a river. I want to clarify:
A watershed is a area were water are flowing to the river or lake, right? I got a one color black area marked after i do the watershed method, and i dont really know what it means.
A pour point is were water flowing out of the lake, am i right?
How could i find out with multiple pour points were the that toxity has its origin? How could multiple pour points constraint my search field?
