MODFLOW DATA MODELAn extension of the Arc Hydro

Groundwater Simulation feature dataset

MODFLOW Data Model Data standard for storing

MODFLOW models in a GIS database

Importing models built externally

Archiving calibrated models Building new MODFLOW

models inside ArcGIS Custom scripts for

analyzing/modifying models can be developed as geoprocessing tools

Ancestral Streams

Ancestral Streams

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
