TwinSc@r™ is a feature that allows connecting the rocsc@r software and platform to third-party digital systems, such as for example a SCADA, or any locally hosted or cloud-based server related to a hydraulic structure. In this way, a digital twin for rock scour may be generated, allowing real-time and even ahead-of-time rock scour assessment on the twinned infrastructure.

This dedicated API (Application Programming Interface) application has a specific user interface that allows easy, fast and universal access to past, current or future scour states of the hydraulic structure being twinned. These different scour states are stored on a database from which the user can retrieve historic information upon demand.

The output that is generated by TwinSc@r corresponds to time-dependent scour states of the rock mass that is impacted by flows from the hydraulic structure that is being twinned.

The different scour states computed by rocsc@r may be visualized by TwinSc@r in different manners, depending on the time-span of the computations compared to the real time (UTC-based):

• Design flood events: Scour results generated by synthetic flood hydrographs, i.e. prescribed return periods, PMF event and so on. Such scenarios are independent from the real-time and physical situation, and may be pre-defined and stored as reference results in the twin environment.
• Real-time flood events: Scour tracking in real-time (UTC-based) based on sequentially transmitted values of monitored variables or spillway outflows – note: real-time rock scour is only tracked digitally, not physically.
• Prognostic flood events (Forecast): Scour forecasting based on prognosis of the near-future spillway outflows, using the real-time scour as initial situation. Such prognosis may be provided automatically by the hydrology building block, or may be made manually through the user interface specifically developed for TwinSc@r.
