Gravel barrier dynamics, coastal erosion and flooding risk
This thesis considers the influence of gravel barrier dynamics on coastal erosion and flooding risk. Establishing the potential for coastal landforms to provide effective risk reduction is salient given growing momentum behind coastal management approaches seeking to incorporate ‘natural’ processes …

The morphodynamics of a sand and gravel barrier, Southern Hawke Bay, North Island, New Zealand
Little is known about mixed sand and gravel beaches over an extended time period (seasons) or for specific wave energy events. This thesis addresses this problem by analysis of the gravel textures (sizes and forms) and the cross-shore transverse profiles for the southern Hawke Bay barrier, which …

Sedimentology and depositional environment of a marine target, Southern Namibia: 3D stratigraphic architecture and diamond mineralisation potential
… the PTA basin is the normal regressive coarse gravel beaches trending shore parallel, with the primary gravel barrier and its preserved coeval back-barrier deposits exceeding 7 km in length. The approximate age of the PTA gravel beaches, due to a lack of absolute age constrains, are estimated …

Morphodynamics, sedimentation and sediment dynamics of a gravel beach
The morphodyiiamics of a gravel barrier beadi in Devon, \JK (Slaptou Sands: tau/S 0.15 - 0.25, D50 2 - 8min), was studied with reference to its sedimentology. Three time scales were sampled for nearshore hydrodynamics, intertidal morphologies and sediirientologies. A series of surveys were carried …
