Experimental investigation of wave-induced morphological changes of gravel beaches
Gravel beaches are widespread around the North-Atlantic Ocean shorelines and can also be found along the coastlines of New Zealand, Russia and the Pacific shore of USA. Over the past decades, researchers in coastal morphodynamics have placed their emphasis on studying sand beaches but gravel …

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 …

Conservation of Least Terns and Piping Plovers Along The Missouri River and Its Major Western Tributaries in South Dakota
… Point and Fort Randall dams, but some sand and gravel beaches, points, or parking lots were used along Oahe Reservoir, and some sand and gravel beaches were used along the Cheyenne River. All tern and plover colony sites were characteristically barren or with short (<10 cm), sparse (<10%) …

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 …

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 …

Influence of beach hydrodynamics on saltwater transport and oil persistence in beaches
… along two transects of a tidally influenced gravel beach in Prince William Sound (PWS), Alaska, which was heavily polluted by the Exxon Valdez oil. The observed data of water table, pore water salinity and tracer (lithium) concentration indicates high freshwater recharge to the clean transect …
