TIDAL SURGE Meaning and
Definition
-
Tidal surge refers to a sudden and significant increase in the level of the sea during high tide, usually associated with extreme weather conditions such as storms or cyclones. It is a phenomenon where large volumes of water are rapidly pushed towards the shore, causing a temporary rise in sea levels above normal tidal heights.
The occurrence of a tidal surge is primarily driven by atmospheric pressure changes and strong onshore winds. When a storm or cyclone approaches a coastline, the low atmospheric pressure at its center can induce a bulge in the ocean's surface, causing water to accumulate towards the coast. This, combined with the strong winds, leads to a rapid and forceful movement of water towards the shore, resulting in a tidal surge.
Tidal surges pose significant threats to coastal areas as they can cause coastal flooding, erosion, and destruction of infrastructure and properties in their path. The increased water levels can flood low-lying areas and breach coastal defenses, resulting in damage to buildings and assets. Additionally, the force of the surge can lead to the displacement of sediment, further exacerbating erosion along the coastline.
Understanding and predicting tidal surges is crucial for the development of effective disaster preparedness and response plans. Advanced monitoring systems, including tide gauges and meteorological tools, help in forecasting the occurrence and magnitude of tidal surges, providing sufficient time for evacuation and preventive measures in vulnerable areas along the coastline.

Etymology of TIDAL SURGE
The word "tidal surge" is a combination of two terms: "tidal" and "surge".
- Tidal: The term "tidal" is derived from the Old English word "tīd", which means "time" or "season". It is related to other Germanic languages such as Old High German "ziot" and Dutch "tij". In the context of "tidal", it refers to the periodic rise and fall of sea levels caused by the gravitational forces of the moon and the sun.
- Surge: The term "surge" comes from the Latin word "surgere", which means "to rise" or "to spring up". It has roots in the Proto-Indo-European language and is related to words such as Old English "sēon", Old Norse "sǽr" and Greek "heuriskein".
