On connecting hydro-social parameters to vegetation greenness differences in an evolving groundwater-dependent ecosystem
Matthew R. Lurtz, Ryan R. Morrison, Pamela L. Nagler
2024, Remote Sensing (16)
Understanding groundwater-dependent ecosystems (i.e., areas with a relatively shallow water table that plays a major role in supporting vegetation health) is key to sustaining water resources in the western United States. Groundwater-dependent ecosystems (GDEs) in Colorado have non-pristine temporal and spatial patterns, compared to agro-ecosystems, which make it difficult...
