If each of the dumps is intended to be a representation of the same conceptual dataset, then even if the content is different (because they have different time-stamps) then they can still all be legitimately considered to be 'distributions' of that dataset. The `dcat:distribution` relationship is mostly about intention. 

But I see that your application has a couple of axes of complexity. 

There a couple of relevant tools in DCAT2: 
- https://www.w3.org/TR/vocab-dcat-2/#temporal-properties shows some patterns for describing regularly updated datasets at the `dcat:Dataset` level. 
- https://www.w3.org/TR/vocab-dcat-2/#qualified-forms provides a generic pattern for linking related datasets together, with semantic relationships indicated by `Roles`. 

I suspect that these might provide a basis for describing your data. But it likely would be more reproducible if there were a couple more classes, something like: 
- `dcat:DatasetSeries` (sub-class or `dcat:Resource`) - a sequence of datasets sharing most of the description but with just the temporal or spatial footprint differing (see #868 on the backlog).
- `dcat:DistributionPackage` - a set of resources, which used together provide a representation of a Dataset - a richer version of bag-of-files
