Severe storms will become more frequent as climate change takes effect, and DCWW is required to report to Ofwat on its resilience to such events. FRM gets to heart of this question, handling large catchments at high resolution, and generating the accurate predictions that DCWW needs to plan and prioritise investment.
Developed by our in-house experts over more than ten years, FRM uses an innovative computation method to speed up the calculations, making it around four times faster than similar tools. Instead of generating a grid of ground conditions for the entire study area before routing the flood water, the grid is created only in areas the water reaches as the flood wave moves through the catchment. This makes it cost-effective and efficient to use across a large area, and DCWW has already been able to map conurbations including Cardiff, Bridgend, Wrexham, Rhyl and others – covering one third of the population of Wales.
We have worked closely with DCWW to ensure FRM has the precise capabilities needed to work with their LiDAR data, and to report the detail required.
