Abstract
The most recognisable geomorphic environments of the Thakuran Basin are river systems of fluvial, estuarine and tidal nature, tidal creek systems and sandy delta beaches. The roles played by these dynamic agencies have given rise to various erosional and accretional features throughout the drainage basin. Natural levees, point bars, mid-channel bars, swash platforms, wash-over flats and an ebb-tidal delta are some of the noteworthy geomorphic features present in the area. Severe bank erosion is observed in areas of high wave action near the mouth of the Thakuran River. Point bars are generally fulcate to crescentic in shape with Epsilon Cross Stratification. Depending upon the distance from the sea, the mid-channel bars show varying composition from mud to sand. Both banks of the Thakuran River exhibit fringing mangrove vegetation. The distal end of the muddy swash platform supports luxuriant mangroves like Phoenix paludosa forests, which is the natural abode for the famous royal Bengal tigers.
