| Abstract: | Trends of
annual sea level records of four tidal observatories of the Hugli
estuary—Sagar, Gangra, Haldia, and Diamond
Harbour—are analysed from
the records of Permanent Service for Mean Sea Level (PSMSL). The rates of sea
level changes for the stations are found to be –3.82, +0.89, +2.43 and +4.85 mm yr–1 respectively, connoting a
significant positive relation between landward distances of the stations and
the rates of sea level rise. This seems to be mainly controlled by disequilibrium
in the morphological state of the landward-narrowing estuary with some
contribution from sediment autocompaction. Sea level trends of the Hugli have
no apparent relation with erosion and accretion of its tidal islands. |
