Quantifying on-farm reservoirs’ impacts on surface hydrology using a multi-sensor approach

Fresh water stored by on-farm reservoirs (OFRs) is a fundamental component of surface hydrology and is critical for meeting global irrigation needs. Farmers use OFRs to store water during the wet season for crop irrigation during the dry season. There are more than 2.6 million OFRs in the US alone, and many of these OFRs were constructed during the last 40 years.

Can we detect more ephemeral floods with higher density harmonized Landsat 8/Sentinel 2 data compared to just one sensor?

Floods, defined as water that temporarily submerges land for over 72 hours or longer, are the largest natural hazard in terms of life loss and economic damage. Effective and immediate disaster response management can reduce the impact of floods but it requires near real-time information on flood occurrence, typically derived based on Earth Observation data.

The Effects of Climate and Human Drivers on Changes in Surface Water in the Southeastern United States

In this study, we assessed how different climate and anthropogenic drivers affect the variability of surface water in the Southeastern United States, an area that has experienced more land cover change than any other region in the country.
