What is a pour point ArcGIS?

The outlet, or pour point, is the point on the surface at which water flows out of an area. It is the lowest point along the boundary of a watershed.

How to create catchment areas in Photoshop 8?

8- Catchment grid delineation: Creates catchment areas with the grids created through the previous steps 6 and 4. The results vary depending on the area chosen in step 6. The smaller the ares, the more catchment areas I get. 9- Catchment Polygon processing: Creates a polygon feature class with the catchment areas created in the step 8.

How to create a Catchment grid in Excel?

7- Stream segmentation: This gave me a grid with cells having unique values per stream, fairly straight-forward. 8- Catchment grid delineation: Creates catchment areas with the grids created through the previous steps 6 and 4. The results vary depending on the area chosen in step 6. The smaller the ares, the more catchment areas I get.
