What is the name of the bulky soil subdivision most often found near streambeds or beaches?

The main idea is how grain shape changes with transport. In streams and along beaches, grains are moved and constantly abraded against other particles and the substrate. This grinding smooths away sharp edges, producing rounded grains. The more they’re transported, the more rounded they become, so rounded is the best description for material found near streambeds or beaches. Angular or subangular shapes indicate little to some transport and fresher edges, while subrounded means only partial rounding; those shapes aren’t as representative of long transport in watery, coastal environments.
