The Coloumn Base

Alsalam alaikom

This is the base of the measuring coloumn ................u can see how the section of the building changes due to water motion and dynamics..........the first section shape was a circle to make the water go circularly ...........that will decrease the impact effect on the walls .............

then the section goes to be a square..........which controls the motion and make it stable to be measured.....

this is a very complicated engineering solutions to be done in that periods and prove how genius were those people
