All in the detail

Alan White (NCE 14 February) asks the extraordinary question as to whether anyone has thought about the implications which the proposed Severn Barrage project could have for sediment to accumulate in the estuary, rather implying that maybe no-one has.

Perhaps it is because this subject has been on the scientific agenda for this project for nigh on half a century that it comes as a shock that anyone can have imagined that it might have been overlooked altogether.

The fact that it is still on the agenda only confirms that important details remain for attention when the preferred project, a task for the Government's current study, is specified – though in broad terms and for clearly understood reasons it neither has for some decades been, nor need it now be, the issue which Mr White fears.
