Software Is Unlocking The Mystery Of Why Rivers Change

Colombian geologist Sara Polanco uses a computer-game-like river modelling software to understand the processes that make and connect river networks, hopefully providing the tools to help better manage water resources in the future. “That software allows me to simulate how rivers change under different scenarios,” Polanco says, “In a sense, it is like a computer game where … Read more…

Earth Surface Dynamics: Tectonically and climatically driven mountain-hopping erosion in central Guatemala from detrital 10Be and river profile analysis

The rise of a mountain range affects moisture circulation in the atmosphere and water runoff across the land surface, modifying the distribution of precipitation and drainage patterns in its vicinity. Water routing in turn affects erosion on hillslopes and incision in river channels on surrounding mountain ranges. In central Guatemala, two parallel, closely spaced mountain … Read more…
