Artificial intelligence (AI) is rife with optimization problems, from automating feature engineering and hyperparameter tuning to training intricate neural networks. Finding a balance between ...

The study of the in situ stress field is significant for the stability of large underground caverns near deep V-shaped valleys. Tectonic movements, gravity and river erosion have a great influence on ...

Collins also noticed unusual river terraces, the stepped structures along the river bank resulting from cycles of the river flooding and then running more quickly, cutting a new channel deeper into ...

Permafrost, the thick layer of perennially frozen ground that covers much of the Arctic, slows down the migration of Arctic rivers, according to a new Caltech study. River migration is a common ...

With steep walls and deep valleys, the Grand Canyon in the western United States or the massive gorges that saw through the margins of the Tibetan Plateau are some of the most awesome and spectacular ...

The Missouri River drains an area of 530,000 square miles and extends over one-sixth of the conterminous United States. The Missouri River originates at the confluence of the Gallatin, Jefferson, and ...

A new study of the freshwater greenfin darter fish suggests river erosion can be a driver of biodiversity in tectonically inactive regions. New findings could explain biodiversity hotspots in ...

The erosion has progressed at an accelerated rate and has reached other rivers, threatening a national highway and Indigenous communities. Studies commissioned by the Ecuadoran government call for ...
