Groynes Introduction. A groyne is an active structure extending from shore into sea, most often perpendicularly or slightly obliquely to the shoreline. Adequate supply of sediment and existence of satisfactorily intensive longshore sediment transport are the sine qua non conditions of groynes efficiency.he wooden groynes are most often one-or two-row palisade structures. Effects of influence of the T-shape wooden pile groyne on the shore (local erosion on the lee side and accumulation on the other) are illustrated in Figure 3.

Methods to reduce coastal erosion A groyne enables to re - align the beach so the community can have a wide beach. Groynes prevent movement of longshore drift so the sand can build up on the beach which protects the beach from erosion. Source: Coastal Management Centre.

Definitions &Translations Groyne. A groyne is a rigid hydraulic structure built from an ocean shore or from a bank that interrupts water flow and limits the movement of sediment. In the ocean, groynes create beaches, or avoid having them washed away by longshore drift.In a river, groynes prevent erosion and ice-jamming, which in turn aids navigation.Ocean groynes run generally perpendicular to the shore, extending from the upper foreshore or beach into the water. All of a groyne may be under water, in which case it is a submerged groyne.n a river, groynes prevent erosion and ice-jamming, which in turn aids navigation.

Grignard reaction The Grignard reaction (pronounced /ɡriɲar/) is an organometallic chemical reaction in which alkyl-or aryl-magnesium halides (Grignard reagents) attack electrophilic carbon atoms that are present within polar bonds (for example, in a carbonyl group as in the example shown below).Grignard reagents act as nucleophiles.tmospheric humidity can alter the yield of making a Grignard reagent from magnesium turnings and an alkyl halide. One of many methods used to exclude water from the reaction atmosphere is to flame-dry the reaction vessel to evaporate all moisture, which is then sealed to prevent moisture from returning.
