Global Rivers Group
We use satellites, models, and fieldwork to study Earth's freshwater
We're a growing academic research group in the Department of Geography at Texas A&M University. Founded in 2018 by Dr. George H. Allen, we are actively recruiting students interested in using emerging technology to tackle global-scale questions involving freshwater resources, floods, and a changing planet.
What we do
We study rivers, streams, and other water bodies using remote sensing, fieldwork, and models. We seek to understand how climate change and land use change are altering the global water cycle, in particular river hydrology. With rapid advancements in remote sensing technology, computing power, and model sophistication, it is truly an exciting time to be studying the global water cycle.
Why we do it
Water is widely considered to be the world’s most vital natural resource, yet freshwater systems are directly endangered by human activities. Our work is motivated by a desire to promote the conservation, management, and understanding of surface water resources worldwide.
