Suspended sediment transport and shoaling in the Munambam fishery harbour, Kerala

Abstract

Results of the monthly synoptic field observations of vertical profiles of suspended sediment concentration, current velocity and salinity carried out in the Azhicode Estuary are presented with a view to understand the shoaling and siltation phenomena in the harbour region. Based on various physical and geomorphological data available on the harbour and near shore region, remedial measures are suggested to prevent the siltation and shoaling at the entrance channel and the sandbar formation at the harbour mouth. This paper also highlights various aspects of hydrodynamics in the lower reaches of the estuary
