It is comprised of different litho-tectonic units manifested by normal/thrust faults and suture zones (Valdiya, K.S., 1977). The Himalayan region has experienced multifaced deformation, spectacular rock assemblages with high-pressure-tempera ...[Read More]

Typically made of rock or wood, groynes are built to limit the longshore transport and loss of shore material like sand or shingle. The build-up shore material captured by the groynes re ...[Read More]
