Communities at Risk Register

The Communities at Risk Register (CaRR) has been developed to provide an objective means of identifying risk and prioritising flood risk management activities at a Wales-wide, community level. It applies a standard methodology across all flood sources to calculate a theoretical ‘danger score’ that allows comparative risks to be quantified and ranked (from High to Low). The CaRR comprises a spreadsheet that identifies and ranks individual communities for, 1. a natural, ‘undefended’ scenario, and 2. a mitigated scenario (based on the presence of defences and flood warning). It is complemented by a GIS layer which defines the individual Community polygons and is attributed with danger scores, community rankings and other metric information.高危社区登记册（Communities at Risk Register，CaRR）旨在提供一套客观方法，用于识别洪水风险，并在威尔士全域的社区层面确定洪水风险管理工作的优先级。该登记册针对所有洪水成因类型采用统一方法体系，计算理论「危险分值」，从而实现可比风险的量化与分级（由高至低排序）。 本登记册包含一份电子表格，可针对以下两种场景识别并分级排序单个社区：1. 自然「无防护」场景；2. 缓解场景（基于防护设施与洪水预警的布设情况）。此外，其配套有地理信息系统（Geographic Information System，GIS）图层，该图层划定了各社区的多边形边界，并标注有危险分值、社区分级及其他指标信息。
