CELL3D Features

Ancestral Streams

Riverbank Model Layer 1

Consists of sands, silts, and clays from floodplain and alluvial deposits

Superjacent ancestral stream channels cut across this formation creating lateral channels of gravels and unconsolidated sediments

Predominantly consists of sands, silts, and clays Superjacent ancestral stream channels cut across this

formation, creating lateral channels of gravels and unconsolidated sediments

Turlock Lake Laguna FormationModel Layers 3,4 and 5

Composed of two dominant units: Black andesitic sands “salt and pepper sand” and blue

and brown clays Hard gray and black tuff-breccias “lava”

Mehrten FormationModel Layers 6,7 and 8

Consists of rhyolite ash, quartz sand , and ashy clay

Valley Springs FormationModel Layer 9

Consists of sandstone, silts, and clays
