Abstract
Using Remote Sensing and GIS to Compute Evapotranspiration in the Rio GrandeTrack: Water Resources
Author(s): Julie Coonrod
Increasing demand for water and the scarce supply of water is a growing concern in the semiarid regions of the United States and the world. Semiarid regions lose a tremendous amount of water to evapotranspiration. The middle Rio Grande bosque has native cottonwood trees and invasive salt cedar trees. Four towers extend above the tree canopy to measure evapotranspiration from the two tree species. Landsat data and AVHRR data are used in ArcView Image Analysis and ArcView Spatial Analyst to derive a method to compute evapotranspiration purely from satellite imagery.
