Stream distances from multiples indutries to a sampling point

QuentinDubois — Thu, 16 Jul 2026 15:16:14 GMT

Hello everyone,

I was wondering if you can help with my problematics. I am working on the contamination by PFAS and their sources. To do that I generate watershed for each of the sampling point, then for each watershed I filtered all the industries present to keep only the ones that may have used PFAS.

Now i want to do some stats about the number of industries per watershed and i want to weight my data using the stream distances between the industries and the sampling point of a watershed but i didn't finfd a way to do it. So i was wondering if anayone has an idea of how to do it.

I am new to the uses of ARCGIS so i am sorry if my request is not at the right place,

Thank you for your help!

Quentin

Do you have the spatial analyst extension?

An overview of the Hydrology toolset | ArcGIS Pro documentation

There is a hydrology toolset with tools to produce some of the data you need.

Your end product will depend on what you have in terms of input data, the software extensions and your familiarity with gis workflows

Hello,

Thanks for your answer, yes i have it i used it to built the watershed of each sampling points, i tried to used the tool flux lenght to associate each indutries to the sampling points but it does not work, all the lenght are equivalent which is not possible. I am new to gis workflows, i only attend a 20h formation during a week to learn the basics.

Do you have any idea of how i can do that ?
