Flood Studies Update (FSU) Physical Catchment Descriptors (Gauged) 2025HIGH VALUEOffice of Public WorksEnvironmentAbstract: These statistics have become what are now known as physical catchment descriptors (PCDs). A PCD describes a characteristic of a catchment as a single number. A list of the most commonly used PCDs in the FSU methodologies are summarised as follows; Catchment Area...
