Observation on Foreshore Morphodynamics of Microtidal Sandy Beaches

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.
