Operations Decision Support System
Goal of the Operations
Decision Support System:
to control the
hydraulic head
and water flow
in water control units
(WCU’s)
in a satisfactory manner
A WCU is a body
of water that is
surrounded by
control
structures

Existing RSM Models
Goal – to simulate the distribution in
space and time of hydraulic head
and water flow in surface water,
shallow groundwater and
SWFFS
canal systems under
alternative management policies.
Time horizon is
in daily time steps

Multipatch
A multipatch is a volume built by joining
surfaces. Each layer is a set of multipatchs
developed from the original triangular mesh

Flood Modeling and Managment
• Goals:
– Flood management in
the District
– Flood evaluation for
CERP
– Flood mapping for
FEMA
• C-4 Basin is a sample
study region
C-4
C-4 Basin
• Drainage areas
defined within basin
• More structures
• Same base hydro
network
• Flood simulation
models in XPSWMM
• Short time horizon of
events (~ 3 days)

and statistically
summarize that pattern
• 21 stage gages
