Why are there no River Deltas in Britain ?
All deltas need to run out onto vast areas of flat land,like the Nile and Mississippi deltas,we only have one area like that and that`s the Wash between Lincolnshire and Norfolk and there are only 2 or 3 very small rivers flowing into that unlike the Nile etc edit,,imagine you have a bucket of water and you splosh it out over a large flat pavement/patio,it will spread out and trickle away into little streams,rather like a delta,you need vast amounts of water to maintain a delta,the Nile and Mississippi can do that,The Wash is quite small in comparison and has no big rivers flowing into it,
