When soil behaves like a liquid it can lose its ability to support structures. The soil can even flow down very gentle slopes, and erupt to the ground surface to form sand boils (“sand volcanoes”).

We are developing multi-scale methods to capture the phenology of cheatgrass with harmonized Landsat and Sentinel satellite imagery, high resolution Planet imagery, and experimenting with centimeter-scale uncrewed areal systems (UAS) multispectral imagery.

Exotic annual grasses such as cheatgrass (Bromus tectorum) have heavily invaded portions of the western United States, rapidly degrading habitats and increasing wildfire risk.

In August 2023, the USGS National Uncrewed Systems Office (NUSO) participated in a collaborative field campaign to collect remote sensing data over agricultural crop fields in California's Central Valley. Hyperspectral satellites were commissioned in coordination with hyperspectral UAS flights at an altitude of 300 feet above ground level.

Engagement steps used in a coproduction process to develop scenario narratives, translate narratives to models, select key model parameters and applications for model outputs, and develop and deliver data products on projected flooded waterbird habitat in the Central Valley of California. Byrd et al. 2023.
