Combined 1D/2D modeling can support Emergency Action Planning
Using combined 1D/2D modeling in support of Emergency Action Planning can provide cost-effective, accurate results. Recently I developed a series of models that included hydrologic routing of precipitation, one-dimensional hydrodynamic routing of flows within a series of three flood retarding structures, dam break modeling at 13 separate locations, and two-dimensional flow modeling through a mixed urban/rural community.
The two-dimensional model included the potential failure of residential privacy walls and the potential failure of two large irrigation canals. All the results from these models were synthesized into understandable maps to help emergency managers.
Using 1D modeling in the impoundment area and 2D modeling in the dam break inundation area minimized the client’s cost without sacrificing accuracy. At the end of the day, this approach works to protect what is most important as we consider dam safety: the health and safety of our communities.
Curious about using combined 1D/2D modeling in support of Emergency Action Planning? I’ll be discussing this topic in greater detail at the HydroVision International Conference in Portland, Oregon later this month. I’ll be in Session 21, Hydraulic and Hydrologic Modeling, from 11:00 AM to 12:30 PM on Wednesday, July 24, 2019. I look forward to seeing you there!
