Wave shoaling is the process when surface waves move towards shallow water, such as a beach, they slow down, their wave height increases and the distance between waves decreases. This behavior is called shoaling, and the waves are said to shoal.n a nautical sense, a bar is a shoal, similar to a reef: a shallow formation of (usually) sand that is a navigation or grounding hazard, with a depth of water of 6 fathoms (11 metres) or less. It therefore applies to a silt accumulation that shallows the entrance to or course of a river, or creek.

Inorganic phosphorus in the form of the phosphate PO3â 4 is required for all known forms of life, playing a major role in biological molecules such as DNA and RNA where it forms part of the structural framework of these molecules.he first form of elemental phosphorus to be produced (white phosphorus, in 1669) emits a faint glow upon exposure to oxygen â hence its name given from Greek mythology, ÏÏÏÏÏÏÎ¿Ï meaning light-bearer (Latin Lucifer), referring to the  Morning Star , the planet Venus (or Mercury).
