Planning & Designing a Digital Twin Model for Urban Flood Risk Reduction Infrastructure
Malay Ghose Hajra & Joey Coco

A digital twin (DT) is a virtual model of a physical asset federated with static and dynamic data. A digitized model of a civil infrastructure can play an important role for data visualization, presentation of information, and comparison of changing conditions. A DT also can have the ability to monitor health and performance of the physical asset, typically in real time. This would ensure efficient operation of important infrastructure throughout its entire life cycle.

The Southeast Louisiana Flood Protection Authority – East (SLFPA-E) is tasked with Operations and Maintenance of the Hurricane and Storm Damage Risk Reduction System (HSDRRS) in greater New Orleans area. To enhance its O&M capability, SLFPA-E recently embarked on a pilot study to create a DT model of one of the Permanent Canal Closures and Pumps (PCCP) stations.

Forte and Tablada used a combination of intelligent drone photogrammetry, terrestrial laser scanning, and underwater multibeam sonar technology to capture suitable data to create a three-dimensional base model of the facility. A variety of static and dynamic data were added to the base model to create a virtual digital twin of the PCCP facility.

This presentation will illustrate the steps involved in field data capture, processing, and creation of the 3D base model. The progression of data federation and use of the virtual digital twin model in operations and maintenance also will be discussed.
