Why were historical period ports of Goa located away from the coast? The decline of Gopakapatana
(CSIR-NISCAIR, 2014)Most of the ports of the historical period of the east and west coasts of India were located away from the seafront But in later period, new ports were established mostly along the coastal regions The reasons attributed ... -
Comparison of ERA-Interim waves with buoy data in the eastern Arabian Sea during high waves
(CSIR-NISCAIR, 2014)Wave data during extreme conditions is required for planning structures and shipping routes Since the measured wave data is still sparse in the eastern Arabian Sea wave information is mainly derived from wave model dataset ... -
