Freak waves off Ratnagiri, west coast of India
(CSIR-NISCAIR, 2014)Freak waves are relatively large and spontaneous ocean surface gravity waves whose heights are larger than the expected maximum wave height for a given sea state Wave data collected off Ratnagiri, along the west coast of ... -
Surfzone currents at Candolim and Miramar beaches of Goa, India: measurements and comparisons
(CSIR-NISCAIR, 2014)Measurements in the surfzone current are often carried out using Acoustic Doppler Velocimeters, Electromagnetic current meters, as well as visual observations based on floats A simple approach is used to install an Aanderaa ... -
Impact of shamal winds and swells on the coastal currents along the west coast of India
(CSIR-NISCAIR, 2014)Wind, wave and current data collected at/off Ratnagiri, west coast of India were analysed to study the wind-wave-current interaction along the west coast of India (WCI) during shamal events Shamal winds which originate in ... -
Estimating absolute sea level variations by combining GNSS and Tide gauge data
(CSIR-NISCAIR, 2014)Indian tide gauges can be used to estimate sea level rise. To separate relative sea level rise from vertical land motion at the tide gauges, various GNSS stations have been installed in the last years at, or nearby, tide ... -
Sediment characteristics at intertidal regions across Yarada beach, East coast of India
(CSIR-NISCAIR, 2014)Sediment samples were collected once a month at five different inter-tidal zones across Yarada beach during May-2009 to May-2010 These sediments are characterized by bimodal and unimodal behaviour and most of them are ... -

Sand spit and shoreline dynamics near Terekhol river mouth, Goa, India
(CSIR-NISCAIR, 2014)Evolution of shoreline and sand spit at the mouth of the Terekhol River, near Keri beach, located in the Indian state of Goa has been investigated From the analysis of the data collected, the shoreline oscillation (accretion ... -
Seasonal variations of total suspended matter (TSM) in the Gulf of Khambhat, west coast of India
(CSIR-NISCAIR, 2014)Total Suspended Matter (TSM)is an important parameter for determining the water quality in coastal regions as it is responsible for the reduction in the light available to the aquatic vegetation which subsequently alters ... -
