Tidal Gauge

A tidal gauge, or tide gauge, is a scientific instrument used to measure the changing levels of sea water along coastlines. It records the rise and fall of tides, which are caused by the gravitational pull of the moon and sun, as well as other factors like wind and atmospheric pressure. By continuously monitoring these levels, tide gauges help in understanding patterns of sea level changes over time. This data is crucial for navigation, coastal engineering, and studying the impacts of climate change, such as rising sea levels and increased flooding risks in vulnerable areas.
