The effectiveness of transition groynes for the protection of Alappad coast is numerically investigated using the software MIKE 21. The study area comprises of a coastal stretch of 3.5 km along shore and 6.5 km offshore. Results reveal predominant longshore transport which favours selection of groynes as a coastal protection measure. Parametric studies are conducted to reach a suitable configuration of transition groynes that drastically reduces the sediment transport rate especially during monsoon. Design of the proposed groyne field is also presented.
