- How many Green Reservoirs for effective SUDS to contain loss
- As many as possible (more . . ); diffuse attenuation to reduce local impact (more . . .)
- For rural ‘Natural’ floods, Upper Severn evidence indicates that 10% reduction (of overbank flow by stage) would have a dramatic effect on loss and blight; 25RP-50RP floods are the problem (more . . . )
- RAF (Run-off Attenuation Feature) research is promising: (more . . . )
- Strategic Locations
- Wherever floodwater stands or flows (more . . . ).
- Lateral impact from such temporary flood storage engineered for longer duration to avoid increased stage (more . . . ).
- Infrastructure crossings (more . . . )
- Incremental Attenuation for Cumulative effect
- Multiple porous features each creating a weir when terrain is inundated (more . . . ).
- Every field in a floodplain is a potential green porous reservoir (more . . . )
- Multiple Benefits
- Hydraulic effect of frictional corridors (more . . . . )
- Pollution control by buffer-strip filtration (more . . . ):

- Biodiversity within boundary friction corridors (more . . . )
