Rama Setu: stability of a deep channel in a slope

From Tuticorin to Dhanushkodi, the sea-bed rises from 3000m depth (near Tuticorin) to about 3 ft. below the sea (near Dhanushkodi). One can visualise the mountain stretching over a steep slope over a distance of about 75 kms. as shown in this image.

 If a 300 m. wide and 12 m deep channel passage is sought to be cut through this slope and beyond Rama Setu (represented by the peak of the mountain), how stable will the channel passage be?

 Without protective embankments on either side of the channel, won’t the channel passage be subject to continuous erosion of the banks and accumulation of shoals in the passage given the currents and counter-currents in the Rama Setu region, with Rama Setu acting like a sieve separating out the higher density mineral, Thorium 232 and creating the placer deposits in Manavalakurichi (Tamilnadu) , Aluva and Chavara (Kerala).

 This is the reason why ARamaswamy Mudaliar Report of 1956 categorically said that any idea of cutting a channel passage through Adam’s Bridge should be ABANDONED. Why has the present alignment been chosen ignoring this Report?

Why can’t an alignment through Dhanushkodi be chosen to create a land-based, controllable canal instead of a channel in mid-ocean?

 With such a land-based canal, locks should also be provided on either end of the canal to prevent the incursion of violent currents of Bay of Bengal into the serene waters of Gulf of Mannar.

 Questions to ponder. Questions which should be answered by the pundits seeking to create history by destroying history.
