Wave fields, both measured and forecast during the very severe cyclone Phailin, are discussed in this communication. Waves having maximum height of 13.54 m were recorded at Gopalpur, the landfall point of the cyclone. The forecast and observed significant wave heights matched well at Gopalpur with correlation coefficient of 0.98, RMS e rror of 0.35 m and scatter index of 14%. Forecasts were also validated in the open ocean and found to be reliable (scatter index < 15%). The study also revealed the presence of Southern Ocean swells with a peak period of 20-22 sec hitting Gopalpur coast along with the cyclone-generated waves.Keywords

Foreshore morphology and morphodynamics were examined to identify stability of two microtidal sandy beaches, Kundapura and Padukare, along the Karnataka shoreline on the west coast of India during three annual cycles from March 2008 to March 2011. The net observation at both sites exhibits slow rate of sediment accretion followed by non-uniform sediment erosion and accretion processes. Study revealed that the beaches are unfavourable for recreational activity because of their narrow width and steeper slope. During summer monsoon, the absence of backshore zone at Padukare makes it more vulnerable to erosion than Kundapura beach.Keywords
