Swale - Cut/Fill

SamMaher — Wed, 11 Sep 2024 20:27:00 GMT

Here's what I'm trying to accomplish:

-Quantify the volume of material removed from a swale using the cut/fill analysis tool in an ArcGIS Pro scene.

-Having this swale at specific elevations at a specific slope to get the correct drainage.

Data I have:

-DSM (.tiff) data for Z for the whole residential site

The current process and where I got stuck:

Add elevation points roughly following where swale would be, on the existing surface
Line feature connecting these dots in rough shape of 2D swale
Buffer around 2D line feature (this tool creates a new feature)
Cut/Fill analysis on this 'buffered' line
Use rotation tools in this analysis to get the rough idea of the slope of the swale
Create new polygon from this analysis (approximately at the elevations needed)
From here I'm stuck. Need to figure out how to get the exact elevations needed on this analysis polygon so that the swale can be adjusted to the elevations/slope needed. I also need specific dimensions in a 3D space (5ft wide swale).

Thank you for your help!
