Dense stacks of images to create cloud-free map composites. In this case at the confluence of the Sacramento River and San Joaquin River in California, cloud-free composites include winter inundation and allow the team to measure seasonal surface water variability. The yellow circle highlights where surface water varies the most over the time series.

At the Cienega Ranch, near Willcox, Arizona, in the foothills of the Dos Cabeza Mountains, a rancher is working to restore and conserve high- quality native grasslands and critical wildlife habitat, while keeping the land as a working cattle ranch.

Hanna Coy led the hydrologic experimental design and data collection. At the Cienega Ranch, near Willcox, Arizona, in the foothills of the Dos Cabeza Mountains, a rancher is working to restore and conserve high- quality native grasslands and critical wildlife habitat, while keeping the land as a working cattle ranch.

Andy Bennett helped collect measurements throughout the study. At the Cienega Ranch, near Willcox, Arizona, in the foothills of the Dos Cabeza Mountains, a rancher is working to restore and conserve high- quality native grasslands and critical wildlife habitat, while keeping the land as a working cattle ranch.

Cienega Ranch weir study site Small Unmanned Aircraft Systems (sUAS; a.k.a. ‘drone’) were flown to acquire high-resolution imagery and to create high-resolution digital terrain models (DTM). Cross-sections, perpendicular to flow, were calculated from the digital terrain models at treatment sites and surveyed using an optical/laser level and rod.

Cienega Ranch Panorama of leaky weir. We identify a large, perched aquifer in the alluvium that is being recharged via diffuse rainfall to support vegetation and grassland health …with a publication forthcoming (stay tuned)!
