Sand is driven clockwise by tidal currents round a diamond-shaped sand shoal in the entrance to the harbour at Wells-next-the-Sea. A population of dune bedforms occupying the ebb-dominated channel on the western side of the shoal was monitored for a

Five morphostratigraphic units of estuarine alluvium in an erosively off-lapping relationship underlie the now almost totally reclaimed post-glacial wetland enclosed by the great bend in the upper Severn Estuary at Arlingham. The oldest unit is mud-d

Except for the interest aroused by their cemeteries, the extramural territories of the Roman cities of Britain have never aroused sufficient interest for them to have been subjected to systematic exploration. Nevertheless, as a sensitive barometer to

The Severn Estuary on the west coast of Britain is large, macrotidal and well mixed, receiving fine sediment from many sources. Within the last few thousand years, at least four discrete lithostratigraphic units, predominantly of sandy to silty clay,

The shore of the former tidal wetland northeast of Cardiff, called the Wentlooge Level and reclaimed during the Roman period, exposes a series of late Flandrian lithostratigraphic units dominated by estuarine clays. Chief among these are the (upper)

The structures are interpreted in terms of a regularly repeated downstream sequence of flow configurations involving (1) a hydraulic jump upstream of each rib, which acts as a local flow control, (2) a critical flow above the rib and a steep cascade

Field studies, including the close temporal monitoring of selected sites allow desiccation cracks in the hypertidal subzone to be classified on the basis of (i) degree of desiccation, (ii) overall shape of individual cracks, (iii) shape of crack marg

Large-scale cross-bedded units with mud-draped bottomsets and foresets occur in several shallow-marine sand formations attributed to tidal sand waves. The deposition and preservation of mud drapes on sand waves are favoured by a large sand-wave asymm

Laminated and nonlaminated sandstones, shales, mudstones, siltstones, shaly conglomerates, and breccias are the principal rock types represented in the Mam Tor sandstone member of the Kinderscoutian stage of the Namurian (Carboniferous). They form a
