Welcome! 

This is the home of TD Geomorphology Laboratory, led by Dr. Tian Y. Dong, hosted by the School of Earth, Environmental, and Marine Sciences (SEEMS) at the University of Texas Rio Grande Valley (UTRGV).

What is geomorphology?

The science of “scenery” – understanding the processes that shape the surfaces, like mountains and valleys, on Earth, Mars, and other planets.

What does our lab study?

Our Lab uses sediment transport and fluid flow theories, field and remotely sensed observations, and numerical models to explore modern surface dynamics, including rivers, deltas, and coastal environments. We also uncover ancient sedimentary records, offering insights into climate change, environmental resilience, and the geological history of our planet. 

Why is geomorphology important?

As the climate rapidly changes due to a combination of human and natural causes, disasters like flooding are expected to be stronger and occur more frequently! Moreover, coastal landscapes are experiencing an unprecedented erosion rate due to the rising sea levels. Geomorphologists have the skill sets and abilities to analyze and explain past land surface changes and make predictions to help us mitigate the risks of climate change, as 10% of the world's population lives in coastal regions.
