Interesting article regarding a claim that an archaeologist has found the citadel captured by King David during his siege of Jerusalem

On the assumption that there are unlikely to be two such water supply features belonging to the same city in the same period, I think he is right. 

The question seems to centre on the following:

Ronny Reich, who was Shukron's collaborator at the site until 2008, disagrees with the theory. He said more broken pottery found [sic] from the 10th century BC, presumably King David's reign, should have been found if the fortification had been in use then.

Shukron said he only found two shards that date close to that time. He believes the reason he didn't find more is because the site was in continuous use and old pottery would have been cleared out by David's successors. Much larger quantities of shards found at the site date to about 100 years after King David's reign.

David's reign is reckoned as c.1010-970 BC.  Leaving aside the ongoing dating controversies of whether certain pottery types belong to the 10th or 9th century BC, water shafts are much less likely than pottery to be cleared away, and one can envisage an attacking force advancing up the water-shaft not wishing to advertise their presence by making a lot of echoey crunching sounds, so they would have a motive for clearing out extant pottery shards of exactly the period in question (and presumably some earlier) and hence quite unintentionally causing a headache for later archaeologists who assume that earlier humans always and invariably pile up the correct number of pottery shards so that shard-based dating procedures will always work.

Indeed having seen pictures of the shaft I can imagine regular users of the shaft getting pretty fed up with anyone who didn't sweep up dropped pots
Skiing downhill on wet shiny pot shards is probably something you can get too much off
