Description
Three probability levels of river flood hazard maps are available, including a 1000-year return period and a 2080s climate change scenario based on UKCP09 high emissions predictions. The maps show flood extent, depth, and velocity where appropriate, produced by the Government Digital Service. The high probability event reflects observed flooding from the last few decades.
Use Cases
Modeling flood risk for infrastructure planning based on the provided flood extent and depth layers.
Assessing long-term climate change impacts on floodplains using the 2080s high emissions scenario.
Prioritizing flood defense investments by comparing high (10-year), medium (200-year), and low (1000-year) probability events.
Creating regional hazard maps for policy consistency, as the return periods align with Scottish Planning Policy.
Strengths
Includes a specific future climate scenario defined by UKCP09 2080 high emissions 95%ile predictions.
Covers three distinct flood probability levels with defined return periods (10, 200, and 1000 years).
Maps contain multiple hazard dimensions: extent, depth, and velocity where appropriate.
