AND OTHER WATER WAVES 239 



face or front slope of the whole flood tide re- 

 garded as one wave, then its length is indefinitely 

 great as compared with the depth of the Severn 

 at Priding, and the only change on entering slightly 

 deeper water would be an increase of speed, 

 accompanied by diminution of height and, perhaps, 

 of steepness. There would be no resolution into 

 a group of waves. It appears, on the contrary, 

 that the greater part of the (no doubt complex) 

 wave which was seen to approach Priding was 

 " long," as regarded the shoal water, but " short " 

 as regarded the deeper water. 



From Priding or Framilode to Hock Crib, or 

 Hock Cliff, as it is also called, is the last great 

 horseshoe bend of the permanent banks of the 

 Severn. Below Hock Cliff are the straight diverg- 

 ing banks, with a straight axis, which indicate the 

 subordination of fluviatile to estuarine conditions. 

 Already in the stretch from Framilode, past Newn- 

 ham at the apex of the horseshoe bend, to Hock 

 Cliff, we see the near approach of estuarine condi- 

 tions in the rapid divergence of the banks, and in 

 the sand-banks, dry before low water, which are 

 here a feature of the river. 



The bore at Newnham is a less imposing wave 

 than in the narrower river from Denny to Stone- 

 bench, where the whole width of the channel is
