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

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

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 XP-SWMM
• Short time horizon of events ( 3 days)
