Although I like your photo collection of Egypt, this one is a misleading, this is not the Nile river, this is a waste tunnel.

This is a break-through into a karst terrain, fairly common in the region, which is underlain by Paleozoic sedimentary rock. This is NOT a "meteorite hole". There are a number of these skylights, especially in Oman - including the famous 'Ubar site. One opens to a cave big enough to hold several 747 aircraft.
During one crossing of the deep Empty Quarter (from al-Shorurah to al-Karkeer to the Wabar asteroid impact site to Dhahran), I used a VLF-EM system and could map groundwater within 60 meters of the surface. It appears that water falling historically and prehistorically in northern Oman and northern Yemen eventually makes its way to the Gulf as a highly alkali groundwater.
