What Si Brings to the Project:
• Experience supporting groundwater models, sustainable yield studies, and calculating water budgets—
help provide more accurate and thorough models and studies to inform options to improve basin
sustainability
Si Si has more than five years of experience in groundwater and environmental investigations performed
for numerous municipalities, state agencies, and private clients throughout California. She regularly
performs ground water flow and solute transport modeling, hydrogeologic investigations, ground water
basin and water quality studies, watershed modeling and management, groundwater waste discharge
permitting, GIS mapping, and database development and management.
Selected Project Experience:

Yucaipa Valley Water District: Recycled Water Use Evaluation - Gateway Subbasin of Yucaipa GW
Basin - Si developed focused groundwater model for the unconsolidated sediments of the Gateway
Subbasin and solute transport model MT3DMS, evaluated the effects, including travel times and percent
contribution, of recharging recycled water at the Wilson Creek Spreading Basin under various recharge
scenarios.

City of San Bernardino: US EPA Model - Si prepared the SBBA HSPF watershed model input data and run
model; prepared recharge packages regarding stream bed percolation, mountain front runoff and areal
recharge for Groundwater Flow Model based on water balance analysis from HSPF.
San Bernardino Valley Municipal Water District: Santa Ana River Integrated Model - Si is supporting
our team in an effort to use existing groundwater and surface water models to develop an integrated
watershed model for the upper Santa Ana River. The resulting Upper SAR Integrated Model (or
Integrated SAR Model), will be used to determine what factors may contribute to declines SAR flows,
and assess cumulative effects on SAR surface flows and groundwater levels.
City of Oceanside: Feasibility of Seawater Desalination in the Mission Narrows - Si incorporated two
previous developed models, the Mission Basin Model and the Camp Pendleton Desalination
Groundwater Model, the Oceanside Harbor Groundwater Flow Model was developed to assess
desalination impacts on coastal and inland areas. Used SEAWAT solute transport model for predictive
scenarios to evaluate percentage of ocean water pumped during the Project, in terms of the
concentration of TDS, and salinity changes at various locations in the model area.
