Investigation of near-shore processes along North Goa beaches: A study based on field observations and numerical modelling
Prakash, N.; Ashly, K.U.; Jayakumar, S.; Harsha, B.; Yadhunath, E.M.; Lavanya, H.; Rajive, K.; ArunKumar, S.V.V. (Springer, 2021)The dynamic coastal environment comprising of near-shore zone and beach continuously undergoes substantial morphological changes due to man-made and natural processes. These processes are always mutually dependent and ... -
Longshore currents on a meso-tidal beach of Goa, India - Measurements and improved formulae
Yadhunath, E.M.; Jayakumar, S.; Pednekar, P.S.; Rajive, R.K.; Gowthaman, R. (CSIR-NISCPR, New Delhi, 2023)Field experiments in the surfzone were conducted on a meso-tidal beach stretch between Sinquerim and Baga off Goa on India's central west coast. Surfzone waves and currents were measured using an array of seabird wave and ... -
Post-monsoon equilibrium beach profiles and longshore sediment transport rates at Candolim, Miramar and Keri beaches of Goa, India.
Jayakumar, S.; Yadhunath, E.M.; Jishad, M.; Gowthaman, R.; Rajasekaran, C.; Pednekar, P.S. (Current Science Association, 2014)Equilibrium profile is one of the concepts in coastal geomorphology which is a result of the balance of destructive versus constructive forces. Two equilibrium beach profile models, viz . Bruun/Dean’s two thirds power model ... -
Rip current occurrences in meso tidal surf zones at a coastal stretch along the central west coast of India
Yadhunath, E.M.; Jayakumar, S.; Jishad, M. (Elsevier, 2022)Currents in the surfzone were measured and modeled along a coastal stretch on the central west coast of India. Wave and tide were the primary forcings for the numerical model, which was validated with the measurements. The ... -
Sand spit and shoreline dynamics near Terekhol river mouth, Goa, India
Rajasekaran, C.; Jayakumar, S.; Gowthaman, R.; Jishad, M.; Yadhunath, E.M.; Pednekar, P.S. (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 ... -
Sediment characteristics at intertidal regions across Yarada beach, East coast of India
Yadhunath, E.M.; Raju, N.S.N.; Ganesan, P.; Gowthaman, R.; Jayakumar, S. (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 ... -
Surfzone currents at Candolim and Miramar beaches of Goa, India: measurements and comparisons
Yadhunath, E.M.; Jayakumar, S.; Jishad, M.; Gowthaman, R.; Rajasekaran, C.; Pednekar, P.S. (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 ... -
Surfzone wave characteristics during flood tide on the central west coast of India
Jayakumar, S.; Jishad, M.; Yadhunath, E.M.; Rajasekaran, C.; Gowthaman, R.; Pednekar, P.S.; Luis, R.; Mehra, P. (World Scientific Publishing, 2015)Surfzone wave characteristics, measured using a wave and tide gauge (WTG) during a flood tide, were studied at three different beaches having different nearshore slopes. The spectral wave characteristics viz., wave-height ... -
Wave height distribution in unsaturated surf zones
Jishad, M.; Yadhunath, E.M.; Jayakumar, S. (Elsevier, 2021)This paper addresses the performance of different wave height distributions in the surf zone on natural beaches on the central west coast of India. The surfzone water level data for different surf zones were analyzed using ...
