Understanding Compound Flooding Through Integrated Modeling

When a coastal storm makes landfall, which poses the greater flood risk: heavy rainfall or storm surge? The answer can be both. Coastal communities can experience multiple sources of flooding simultaneously. Storm surge pushes water inland while heavy rainfall generates runoff and increases riverine flows. Where these processes interact, the resulting compound flooding can create complex—and potentially devastating—conditions that cannot be fully understood by looking at each source independently. Accurately representing those interactions presents an important challenge for engineers and flood risk managers. The Challenge of Modeling Compound Flooding Historically, compound flooding has often been simulated by loosely coupling a hydrologic/hydraulic watershed model with a separate coastal storm surge model. Each model represents an important component of the overall event, but separating those processes can make it difficult to fully capture the nonlinear interactions among rainfall-runoff, riverine flows, and storm surge. The U.S. Army Engineer Research and Development Center (ERDC) developed an advanced version of the Adaptive Hydraulics Model (AdH) specifically to address this challenge. Unlike approaches that model individual flood sources separately, AdH can simulate rainfall-runoff, riverine flows, and storm surge together in a single, monolithic simulation. This allows the model to directly represent how multiple flood sources interact as conditions change throughout an event. Simulating Hurricane Harvey in Harris County DynamicSolutions | DCCM used the advanced version of AdH to perform a monolithic simulation of flooding in Harris County, Texas, during Hurricane Harvey. The analysis identified a 37-kilometer-long compound flooding transition zone within Buffalo Bayou where multiple flood sources interacted. Within a transition zone such as this, flooding cannot necessarily be attributed solely to rainfall, riverine flow, or coastal surge. Instead, water levels reflect the combined and nonlinear effects of multiple processes. A monolithic modeling approach allows these interactions to occur within the same simulation, providing a more complete representation of the resulting water levels and flood conditions. Looking Beyond Historical Events The value of compound flood modeling extends beyond recreating—or hindcasting—past storms. AdH can also be used to run stochastic coastal storm simulations to evaluate flood risk in coastal areas vulnerable to compound flooding. Rather than focusing solely on what occurred during a single historical event, these simulations can help evaluate potential flooding across a range of storm conditions. For communities where coastal surge, river systems, and rainfall-driven runoff converge, understanding these interactions can provide important information for flood risk assessment, infrastructure planning, and resilience efforts. As flood hazards become increasingly complex, the modeling tools used to understand them must be capable of representing that complexity. Integrated approaches such as AdH provide engineers and public agencies with a way to evaluate multiple flood mechanisms as the interconnected processes they are.

Advancing Compound Flood Modeling with an Integrated Approach

Flooding rarely occurs from a single source. During major storm events, heavy rainfall, riverine flooding, and coastal storm surge can occur simultaneously, creating compound flooding conditions that are more complex—and potentially more damaging—than any individual flood process. Understanding how these processes interact is critical to accurately estimating flood hazards and supporting resilient infrastructure planning. Yet, traditional modeling approaches often evaluate individual flood sources separately and then combine the results. While useful for certain applications, this approach may not fully represent the interactions occurring between rainfall, rivers, and coastal systems during an extreme event. DynamicSolutions | DCCM recently collaborated with the U.S. Army Engineer Research and Development Center (ERDC) to advance a more integrated approach to compound flood modeling. Capturing Multiple Flood Processes in a Single Model The project involved implementing an advanced version of the Adaptive Hydraulics Model (AdH) capable of simulating the combined impacts of heavy rainfall, riverine flooding, and coastal storm surge within a single modeling framework. By representing these processes together, the model can account for interactions that may be missed when individual flood sources are modeled independently. This provides a more integrated representation of how water moves through interconnected coastal and riverine environments during major storm events. The approach is particularly valuable in areas where rainfall-driven runoff, river flows, and coastal water levels can influence one another and contribute collectively to flood conditions. Applying the Model to Hurricane Harvey To demonstrate the advanced modeling capabilities, DynamicSolutions | DCCM and ERDC applied the model to Hurricane Harvey in Galveston Bay and Harris County, Texas. Hurricane Harvey provided an opportunity to evaluate a complex event involving multiple sources of flooding across a large coastal and urban environment. Using the advanced version of AdH, the team simulated the combined influence of heavy rainfall, riverine flooding, and coastal storm surge within a single model. Rather than treating these mechanisms as isolated processes, the integrated approach allowed their interactions to be represented directly within the simulation. Improving Our Understanding of Compound Flood Risk As communities plan for extreme weather and changing flood risks, understanding compound flooding is increasingly important. Flood hazard assessments that better represent the interaction among multiple flood sources can provide engineers, planners, and public agencies with more complete information for evaluating vulnerabilities and planning infrastructure improvements. Integrated modeling approaches such as this can help advance the way complex flood events are analyzed—providing a more comprehensive picture of how rainfall, rivers, and coastal systems work together during extreme conditions. DynamicSolutions | DCCM brings specialized expertise in hydrodynamic modeling and water resources engineering to help public agencies and project partners better understand complex flood processes and evaluate infrastructure challenges.

A Practical Approach to Sediment Transport Modeling

Sediment transport modeling can be an important tool for understanding how waterways respond to changes in flow, channel geometry, and proposed improvements. However, comprehensive numerical sediment modeling can also require significant data collection, computational effort, and budget. For many projects, particularly during early planning and alternatives development, that level of analysis may not be necessary. A more targeted approach can provide valuable insight while allowing project teams to focus resources where they will have the greatest impact. Using Hydrodynamic Modeling to Inform Sediment Assessments DynamicSolutions | DCCM recently applied this approach for a U.S. Army Corps of Engineers (USACE) study on the Arkansas River. Rather than beginning with a comprehensive numerical sediment transport model, our team leveraged results from an existing two-dimensional (2D) hydrodynamic model to estimate sediment transport capacity through a problem reach. The hydrodynamic model provided information about hydraulic conditions within the reach that could be evaluated in the context of sediment movement. Using these results, our team developed estimates of sediment transport capacity and assessed how proposed changes could influence conditions within the study area. Supporting Efficient Alternatives Screening The analysis provided a practical way to screen alternative designs for navigation improvements without immediately undertaking a more extensive sediment modeling effort. This type of approach can be particularly useful during early project phases, when the primary objective is to understand relative differences among alternatives and identify concepts that warrant further investigation. By using available hydraulic information to evaluate sediment transport behavior, project teams can narrow the range of alternatives before investing in more detailed analyses. It also allows the level of modeling effort to better match the decisions being made. If an initial assessment identifies significant sediment-related concerns or uncertainties, more comprehensive sediment transport modeling can then be focused on the alternatives and locations where additional detail is most valuable. Matching the Analysis to the Project Sedimentation studies do not always require the most complex modeling approach from the outset. The appropriate methodology depends on the project objectives, available data, site conditions, and level of detail needed to support decision-making. For the Arkansas River study, leveraging 2D hydrodynamic model results provided an efficient means of estimating sediment transport capacity and screening navigation improvement alternatives. The result was a focused analysis that provided useful technical information while recognizing the data, schedule, and budget considerations associated with more comprehensive numerical sediment modeling. By selecting an analytical approach that matches the questions a project needs to answer, engineers can provide meaningful sedimentation insights while reserving more intensive modeling efforts for situations where they are truly warranted.

Unnatural Wonder: Colorado River

This spring DynamicSolutions | DCCM’s own Steve Sanborn joined a Colorado River trip through the Grand Canyon. On the trip happened to be two journalists from The Arizona Republic working on a story about the effects of regulated flows on the Colorado River’s ecosystem. The reporters put together a great story and video, which uses footage and thoughts from Steve’s trip, about the challenges the river faces and efforts to revitalize the ecosystem. “A river once wild, muddy and warm now flows cold and clear, every drop measured out to supply cities and farms downstream. Water levels ebb and flow hourly, erasing the spring surges and summer droughts innate in desert rivers. Scientists manage nature’s cycles, adding what was lost, nursing what remains.” Read the Article
