The Northeastern San Joaquin County Groundwater Banking Authority (GBA) is
developing an integrated regional water management plan (IRWMP) to implement water
resource alternatives with the goal of sustaining groundwater use in the area. In the
systems model, the groundwater basin underneath the GBA region was modeled as five
subbasins based on water districts, cities, and natural boundaries. The GBA model
development focused on constructing a simplified relationship for the interaction between
groundwater and surface water using the detailed groundwater model previously
developed for the study area.
To analyze the preliminary IRWMP alternatives, each subbasin was modeled with its
own inflows and outflows, such as demands, water deliveries, river seepage, deep
percolation, lateral flow from surrounding subbasins, groundwater pumping, and
inflow/outflow from the water supply projects. The projects included new conveyance
structures, new surface water storage reservoirs and diversions, treatment plant
expansion, water transfers, a regional banking program, reclamation, and demand
management measures. Water developed through these projects was used in the model as
new municipal and industrial supplies, agricultural in-lieu deliveries, and direct recharge
to the groundwater subbasins through ponds and field flooding.
The systems model evaluated the preliminary alternatives' overall performance for
subsequent screening and definition of alternatives that allow the sustainable
management of the groundwater basin. The objective of this paper was to discuss the
development of the systems model used to screen the initial IRWMP alternatives based
on increase in groundwater levels, capital, and operations and maintenance costs. Includes 7 references, table, figures.
