USGS Hydrologist Molly Maupin and USGS Research Physical Scientist Gabriel Senay discuss how Landsat imagery has been used by the National Water Census and in studying water use trends.
Gabriel B Senay, Ph.D.
Gabriel Senay is a scientist with the U.S. Geological Survey Earth Resources Observation and Science (EROS) Center, co-located with the North Central Climate Adaptation Science Center (NC CASC) in Boulder, Colorado. He is also an adjunct professor at South Dakota State University and a Faculty Affiliate with Colorado State University, Fort Collins, Colorado.
Senay, with a background in agricultural engineering, hydrology, and remote sensing, conducts applied research on landscape water use assessment and monitoring using satellite-derived data and hydrologic modeling. He has taught courses on remote sensing of water resources and land surveying.
Research topics include:
1) Evapotranspiration modeling for crop water use mapping, drought monitoring, and water budget studies.
2) Runoff and soil moisture modeling for groundwater recharge estimation, small reservoir (pond) monitoring, and ecological drought assessment.
3) Interactions between land cover change and hydrology and their impact on water resources.
4) Spatiotemporal dynamics and trend analyses of agro-hydrologic processes and climatic drivers.
Science and Products
Towards an Integrated Understanding of Terrestrial Evapotranspiration
Terrestrial evapotranspiration (ET), the second-largest component of the terrestrial water cycle, links water, energy, and carbon cycles and influences the productivity and health of our ecosystems. Despite the importance of ET, the dynamics of ET across a spectrum of spatiotemporal scale and their controls are uncertain. During an international ET workshop held in November 2021 by...
Using Satellite Imagery to Estimate Consumptive Water Use from Irrigated Lands in the Milk River Basin, United States and Canada
The U.S. Geological Survey, with the support of the International Joint Commission, and in cooperation with Alberta Environment and Parks, Blackfeet Nation, Environment and Climate Change Canada, and Montana Department of Natural Resources and Conservation, is leading a project that should improve information available to apportion water between Canada and the United States in the St. Mary and...
Eyes on Earth Episode 35 – Watching the Water Supply with OpenET Eyes on Earth Episode 35 – Watching the Water Supply with OpenET
Eyes on Earth is a podcast on remote sensing, Earth observation, land change and science, brought to you by the USGS Earth Resources Observation and Science (EROS) Center. In this episode, we hear about a partnership that aims to simplify and share critical water use data for the Western U.S.
Moving towards EarthMAP: Establishing linkages among USGS land use, water use, runoff, and recharge models
Understanding and anticipating change in dynamic Earth systems is vital for societal adaptation and welfare. USGS possesses the multidisciplinary capabilities to anticipate Earth systems change, yet our work is often bound within a single discipline and/or Mission Area. The proposed work breaks new ground in moving USGS towards an interdisciplinary predictive modeling framework. We are...

Ecological Drought Across the Country
Water resources are critical for ecosystems, agriculture, and communities, and potential climate impacts to hydrologic budgets and cycles are arguably the most consequential to society. Apart from precipitation, evapotranspiration makes up the most significant component of the hydrologic budget. Evapotranspiration is a primary metric for identifying Ecological Drought, a deficit in water...
