Update and Recalibration of the Chino Basin Groundwater Model, Chino Basin
Watermaster, Chino Basin, CA. Senior Hydrogeologist. Assisted in the update and
recalibration of the Chino Basin groundwater and surface water model. The basin geometry
and layering was updated to take into account newly drilled wells. The surface water model
was improved to account for improved resolution of land use data and refined historical/
planning estimates of the deep infiltration of precipitation and applied water. The model was
used to determine the safe yield of the basin, the safe yield created by desalter wells and
reoperation and the state of hydraulic control.
San Juan Basin Groundwater Management Plan and Facilities Plan Update, San Juan
Basin Authority, San Juan Capistrano, CA. Senior Hydrogeologist. Completed a
comprehensive hydrogeologic assessment of the groundwater basin that included
recalculating the storage capacity of the groundwater basin in order to provide a clear
understanding of the basins groundwater resources. The updated plan represents the most
comprehensive “state of the basin” assessment ever done for the San Juan Basin.
Ventura River Integrated Groundwater/Surface-water model, California State Water
Resources Control Board, Ventura County, CA. Senior Hydrogeologist. Provided
hydrogeologic services for the development of an integrated groundwater/surface water
model for the Ventura River watershed. He is responsible for the development of the
conceptual hydrogeologic models for four groundwater basins.
Groundwater Level Monitoring Program, City of Malibu, CA. Senior
Hydrogeologist/Engineer. Managed the groundwater monitoring network with pressure
transducers and monthly manual measurements. Maintains a database of water level data of
the Malibu Civic Center Area for the City of Malibu.
Develop and Apply a Groundwater Flow Model for the Cucamonga Basin, Cucamonga
Valley Water District, Rancho Cucamonga, CA. Senior Hydrogeologist. Developed the
conceptual model and hydrology for the calibration of the groundwater model. Developed
the initial hydrologic budget for the calibration period which includes the subsurface inflow,
deep infiltration of precipitation and applied water, artificial recharge, stormwater recharge
in channels and Conservation/Flood Control Works, groundwater production, and subsurface
outflow. The model will be used to evaluate several future groundwater management plans.
Six Basins Groundwater Flow Model, Six Basins Watermaster, Claremont, CA. Senior
Hydrogeologist. Developed the conceptual model and hydrology for the calibration of the
groundwater model. Developed the initial hydrologic budget for the calibration period which
includes the subsurface inflow, deep infiltration of precipitation and applied water, artificial
recharge, stormwater recharge in channels and Conservation/Flood Control Works,
groundwater production, and subsurface outflow. The model will be used to evaluate several
future groundwater management plans.
Temescal Basin Recharge Master Plan, City of Corona, Corona, CA. Project
Manager/Engineer. The Temescal recharge master plan was developed to provide a
solution to the overdraft of the Temescal Basin which is estimated to be about 3,000 acre-
ft/yr. Mr. Cruikshank was responsible for the development and hydraulic simulations of
multiple recharge scenarios involving the capture of storm water and imported water and
recycled water at both existing and improved basins, as well as detailed cost analysis that
was applied to evaluate each alternative.
Six Basins State of the Basin Report, Six Basins Watermaster, Claremont, CA. Senior
Hydrogeologist. Constructed hydrogeologic cross sections, created several historic regional
groundwater elevation contours maps, evaluated aquifer parameters, mapped the depth to
bedrock, analyzed groundwater in storage and developed yield through GIS applications.
Created the associated report graphics.
