The Dynamic Coastlines of Trinidad and TobagoWhen one thinks of shoreline change, immediately the sensitive topic of land loss comes to mind. Change, however, can be categorised into two main measurable outcomes - erosion (loss of land), and accretion (gaining land). The determination of either of these processes is accomplished through the measurement of shift in the vegetation line along the shore from one year to the next. While the impacts of erosion are more familiar, accretion may also pose difficulty for coastal users and marine life. These effects include: siltation of fish landing sites and ports, the smothering of benthic communities and sea grass beds, and a longer climb to the surface for turtle hatchlings on nesting beaches.
