Abigail Kahler
Abigail joined the USGS Arizona Water Science Center in 2023 and assists the Water Use team with automating GIS processes and estimating crop irrigation water use withdrawals in Arizona.
Research interests include Python for GIS visualization and communication, quantifying agricultural water use in Arizona, and national water use modeling. Prior to joining the USGS, she was a graduate student intern with the Bureau of Reclamation and created a web-app to visualize the results of a regional groundwater study.
