Beach dynamics related to the Ambalapuzha mudbank along the southwest coast of India

Environmental isotopes to test hypotheses for fluid mud (mud bank) generation mechanisms along the southwest coast of India

“…In other months the wind is weakest and is towards the south. Along shore currents are stronger (about 5e40 cm/s) during MarcheSeptember and flow in southesoutheast direction whereas cross shore currents become stronger towards north during NovembereJanuary (Antony and Shenoi, 1993;Narayana et al, 2001). The brunt of high amplitude sea waves occurring during southwest monsoon is responsible for severe erosion of the shore.…”

Application of a new methodology for coastal multi-hazard-assessment & management on the state of Karnataka, India

“…Deep-water waves approach the coast from south-western and north-western directions and the significant wave height, Hs, have been assessed to >3 m during the SW monsoon (Kumar et al, 2010). It has been observed that the long-shore currents are strongest and towards the south during the SW monsoon (Narayana et al, 2001).…”

Shoreline changes and morphology of spits along southern Karnataka, west coast of India: A remote sensing and statistics-based approach

“…Although the overall direction of sediment transport and its mechanisms determine the areas of coastal erosion and accumulation, factors such as intensity of monsoons influence the erosion and accretion patterns along the west coast of India (Narayana et al, 2001). Therefore, it is important to understand how sediments from various sources on the beaches are reworked and redistributed by the nearshore hydrodynamic processes.…”

“…Of the two monsoons, the southwest (summer) monsoon (JuneSeptember) is stronger than the northeast (winter) monsoon (October-December); and during southwest monsoon the coastal current sets-in in clockwise direction, while during the northeast monsoon the current is in the counter-clockwise direction. As a result, the longshore current is stronger and towards the south during the southwest monsoon (Narayana et al, 2001). It can be said that natural processes such as waves, littoral currents, offshore relief, rainfall, and sea-level changes etc., are responsible for erosion/accretion of the coast and subsequent shoreline changes.…”
