SHORT-TERM CHANGES OF BEACH MORPHOLOGY AND SAND GRAIN SIZE UNDER WAVE AND WIND ACTION
"... Wave and wind impacts on short-term backshore processes were investigated in terms of backshore topography, sand grain size, and wave, tide, and wind conditions at an open-ocean dissipative beach in Japan from September 2004 to March 2005. Indices of wave and wind impacts were defined by wave run-up ..."

-up level and wind-driven sand transport rate, respectively. The results show that waves have larger effects than winds on backshore accumulation even in areas where the wave acts on a bed for only a few days a year. Furthermore, both waves and winds cause sand coarsening in the backshore. Run-up waves

Johannessen: Soft Shore Protection as an Alternative to Bulkheads Soft Shore Protection as an Alternative to Bulkheads— Projects And Monitoring
"... Traditional “hard ” bulkheading has been the norm at Puget Sound and Northwest Straits shores until very recently, when “soft shore protection ” alternatives have been encouraged by regulators and well-informed citizens. Soft shore protection locally entails the use of indigenous materials such as g ..."

beach on Blakely Island in San Juan County was restored in early 1998 and the backshore area was extensively replanted. An 850 ft long enhanced beach that included a wide gravel berm and a replenished sandy backshore was constructed at a severely degraded Samish Island beach in 1997. Monitoring results
GPR studies over the tsunami affected Karaikal beach, Tamil Nadu, south India
"... In this study, results of GPR profiling related to mapping of subsurface sedimentary layers at tsunami affected Karaikal beach are presented. A 400 MHz antenna was used for profiling along 262 m stretch of transect from beach to backshore areas with penetration of about 2.0 m depth (50 ns two-way tr ..."

Geomorphological Features and Primary Sedimentary Structures of the Deltaic Coastal Plain Along Burullus
"... ABSTRACT. The Burullus coastal area can be geomorphologically divided Iinto: beach, backshore plain, barrier, tidal inlet and deltaic zones. It shows several landforms characteristic for marine, riverine and aeolian processes. These include: I. Shore landforms: represented by foreshore slop, backsho ..."

TSUNAMI IMPACTS ON MORPHOLOGY OF BEACHES ALONG SOUTH KERALA COAST, WEST COAST OF INDIA
"... The present study is based on the post tsunami survey conducted in January 2005 along the southwest coast of India. Although tsunami affected the whole coastline of Kerala, it devastated the low-lying coastal areas of Kollam, Alleppey and Ernakulam districts leading to the loss of life and property. ..."

of the foreshore and backshore and landward transport of beach material during the run-up of waves at Puthu-Vypeen. The erosion of the backshore (berm) in several places along the coast was quite evident in the study. This has caused reduction in the elevation which may make these areas more vulnerable
Genesis of coastal dune fields with vegetation
"... Vegetation greatly affects the formation and dynamics of dune fields in coastal areas. In the present work, we use dune modelling in order to investigate the genesis and early development stages of costal dune fields in the presence of vegetation. The model, which consists of a set of coupled equati ..."

I Quaternary Sea-level History and Variation in Dynamics along the Central Brazilian Coast: Consequences on Coastal Plain Construction
"... The central part of the Brazilian coast experienced considerable relative sea-level fluctuations during the Quaternary. It has been possible to identify three high marine levels. The last two, during which the sea-level was at a maximum S k 2m (123,000 yr BP) and 4,s * 0.5117 (5,100 yr BP) above the ..."

. The equilibrium profile of a sandy coast will be destroyed with sea-level changes and its restoration will be accompanied by transfer of sands, from backshore and adjacent land areas to foreshore during sea-level rise and from foreshore to backshore
Coastal karst geomorphosites at risk? A case study: the floods
"... Abstract: Extreme rainfall causing floods and great damage occurred in many areas of central-east Sardinia in the period 6–11 December 2004. A total of approximately 700 mm of rain was measured during this extreme event, with a maximum reaching 510 mm of rainfall in 1 day at the rain gauge of Villag ..."
