Bangladesh beaches used to house many beach morning glory plants which protected from soil erosion, but they are quickly disappearing. Bangladesh is home to the longest beach on earth - the Cox’s Bazar-Teknaf sea beach in the Bay of Bengal. In the span of 35 years, from 1989-2024, 1085 hectares of land have degraded at a rate of 31 hectares per year & 284 hectares have accreted at a rate of 8 hectares per year. [Accretion: deposition of sediment; opposite of erosion; occurs when there are calm waters because deposition > removal; degradation: erosion] This has been caused by storm surge, cyclones, waves, current, changes in sea level and climate, beach composition, human interaction, and a large range in elevation between high and low tides. Tropical cyclones cause tidal bores or tidal waves. These occur when the sea level is very high, at the pla...
