MODFLOW-OWHM used to characterize the flow system of the Petaluma River Watershed, Sonoma County, California
The Petaluma Valley integrated hydrologic model (PVIHM) was developed by the U.S. Geological Survey (USGS)
in cooperation with the Sonoma County Water Agency and the City of Petaluma. The PVIHM simulates the
99,000-acre Petaluma valley watershed and includes 54,000 acres where groundwater flow is active. The model
simulates 56 years of historical hydrology (water years 1960–2015) that includes a range of wet and dry climatic
conditions. The model incorporates data collected from local (Sonoma County Water Agency and City of Petaluma),
State, and Federal sources. The PVIHM is an integrated hydrologic model that simulates groundwater-flow,
surface-water flow, and land-surface process systems in a single model using MODFLOW-OWHM. The model
was calibrated using observed groundwater altitudes from 41 groundwater monitoring wells and measured streamflow
data from 3 USGS streamflow gages. The model generates monthly water budgets for water use, groundwater flow,
and streamflow for water years 1960–2015 as well as groundwater altitude hydrographs, simulated streamflow
hydrographs, and maps of simulated groundwater altitude. This USGS data release contains all of the input and
output files for the PVIHM model, which are described in the associated Scientific Investigation Report
(https://doi.org/10.3133/sir20225009)
