Beaches are dynamic coastal features which respond to storms, wind, waves, currents and tides differently dependent on its geology. Notwithstanding the protection by reefs, beaches are generally the primary defenses for any coastal development. Sand/sediment is critical in the protection of the coastline by facilitating the dissipation of energy from wave attack; thereby acting as a buffer to erosion. Beaches however are damaged by sand removal, improper building of coastal protection structures and any activity that prevents new sediment sources from replenishing them. Beach erosion is expected to be exacerbated by impacts due to climate change. This monitoring project which commenced in 1988, documents the erosion and accretion rates of selected beaches and bays in Trinidad and Tobago, and identifies likely causes/ impacts. Twenty seven (2)7 bays in Trinidad (70 stations) and 27 bays in Tobago (55 stations) are currently monitored. Littoral and beach profile data is collected monthly or quarterly basis for trend analysis.
