Wave forces acting on a vertical cylinder at different locations slope beach in the near-shore region are investigated considering solitary waves as incoming waves. Based Reynolds-averaged Navier-Stokes equations and k-ε turbulence model, wave due to interaction between simulated analyzed with incident heights locations. The numerical results first compared previous theoretical experimental val...

Beach topography quickly responds to the action of storm waves, resulting in foreshore erosion and accretion under calm wave conditions after a storm. Field observations were carried out on Chigasaki coast investigate these beach changes. It was found that seabed shallower than 3 m depth rapidly eroded by offshore sand transport during event with deposition zone at depths between 5 m, then reco...

In a coastal zone of seas recreation resources are various. general, they distinguished by 3 blocks, according to features atmosphere, hydrosphere and lithosphere as parts geographical sphere. At the same time, exponents qualities were separated, scales elaborated for every them. The estimations made medicine-biological next exponents: beach, cliff, submarine slope, water, sediment etc.

The process of erosion and desertification affects social communities, agricultural lands and natural resources in coastal areas. The rapid coastline changes would cause social and economic issues in the coastal areas. In this study, Miankaleh coasts and the eastern coastlines of Amirabad port have been surveyed due to existing benchmarks since June 2013 until December 2015 in order to analyze ...

Maintaining food production while sustaining productive ecosystems is among the central challenges of our time, yet, it has been for millennia. Ancient clam gardens, intertidal rock-walled terraces constructed by humans during the late Holocene, are thought to have improved the growing conditions for clams. We tested this hypothesis by comparing the beach slope, intertidal height, and biomass a...

Field and laboratory observations have shown that a relatively low beach groundwater table enhances beach accretion. These observations have led to the beach dewatering technique (artificially lowering the beach water table) for combating beach erosion. Here we present a process-based numerical model that simulates the interacting wave motion on the beach, coastal groundwater flow, swash sedime...
