Morphological changes at Godavari delta region due to waves, currents and the associated physical processes
MetadataShow full item record
Wave conditions, the most important in coastal modification, prevailing in the region of Godavari Delta for different seasons are illustrated. The analysis of GEOSAT altimeter data for the period November 1986 to October 1987 shows that only during the southwest monsoon season waves reach heights of the order of 2 m. Otherwise they are of the order of 1 m. The fair weather promotes delta build-up. Tides and tidal currents are other important factors which affect the overall gradient of the deltas, especially their seaward section. Dye experiments conducted in Kakinada Bay show that tidal currents are generally of the order of 10-20 cm/sec. However, during the period of maximum discharge from the Godavari River (June-November) the ebb current exceeds the speed of 200 cm/sec. The morphological changes due to the effect of river discharge during various seasons and the development of Godavari sand spit off Kakinada and its influence to delta modification are detailed.
