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

Time horizon isin daily time steps summarized monthlycontinuing for years

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 joiningsurfaces. Each layer is a set of multipatchsdeveloped from the original triangular mesh DEMO: ODSSMESH.mxd

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)
