in this paper, the large amount of sedimentation and the resultant shoreline advancements at the breakwaters of beris fishery port are studied. a series of numerical modeling of waves, sediment transport, and shoreline changes were conducted to predict the complicated equilibrium shoreline. the outputs show that the nearshore directions of wave components are not perpendicular to the coast whic...

For crenulate-shaped bays, the coastal outline assumes a specific shape related to predominant waves in area: it generally consists of tangential zone downcoast and curved portion upcoast. Many engineers have attempted derive an expression headland bay shapes that emerge when full equilibrium is reached (stable or dynamic). However, even though models for static bays exist, they are merely empi...

—The Permian is regarded as one of the most crucial intervals during echinoid evolution because crown group echinoids are first widely known from the Permian. New faunas provide important information regarding the diversity of echinoids during this significant interval as well as the morphological characterization of the earliest crown group and latest stem group echinoids. A new fauna from the...

Abstract. Beach erosion at the unprotected downdrift end of a groin is common with waves approaching structure obliquely. This phenomenon has often occurred on side natural groins east coast South Korea during high in winter months. The resulting planform assumes distinctive crenulate shape maximum indentation point landward erosion. An analytical model employed to study beach rock Jeongdongjin...

Characteristically shaped bifacial points are stone artefacts with which the Middle Stone Age Still Bay techno-complex in Southern Africa is identified. Traditional approaches such as chaîne opératoire and two-dimensional metrics in combination with attribute analyses have been used to analyse variability within Still Bay point assemblages. Here we develop a protocol to extract and analyse high...

A new monobasic genus of Nanophyidae, Indophyes, and a new species, I. yaromi, are described from southern India (type locality: Karnataka, Bilukoppa, 800 m, 40 km W Mudigere). The new genus is characterized by 5-segmented antennal funicle, strong sexual dimorphism of the rostrum, dentate femora, male tibiae unarmed, abdominal suture IV distinct in both sexes, male pygidium not foveate and 8 el...

A new solitary entoproct, Loxosomella unicornis sp. nov., is described. The species was found on the gymnolaemate bryozoans Cribrilina sp. and Electra sp. in Kandalaksha Bay, White Sea. Loxosomella unicornis sp. nov. is a medium-sized species with a total length up to 650 µm, eight tentacles and a conspicuous horn-shaped appendage on the top part of calyx.
