The distinction between preventive and curative deployment of the NoFloods Flood Barrier lies in the timing and purpose of its installation:
- Preventive Deployment: Preventive deployment involves positioning the barrier before flooding occurs, with the aim of safeguarding a specific area or structure. The barrier is set up in anticipation of rising water levels, acting as a proactive defence mechanism against potential flooding. This deployment strategy is effective when there is advanced notice of an impending flood, allowing time for preparations.
- Curative Deployment: Curative deployment takes place during an ongoing flooding event, directly into the water. This method is commonly used to encircle flooded structures or installations, such as substations. The intent is to create a barrier to contain the water and then use appropriate pumps to drain the area enclosed by the barrier. While it is possible to curatively deploy the barrier, this is typically more feasible when dealing with relatively shallow flood depths, allowing machinery and vehicles to access the site.
It’s worth noting that while curative deployment is an option, preventive deployment is generally preferred, assuming there is sufficient lead time for protection measures. This approach is particularly effective when a flood Early Warning System is in place, as it allows for proactive actions to be taken in response to forecasts of flooding. Ultimately, the choice between preventive and curative deployment depends on factors such as the flood conditions, available resources, and the time frame for response.
