The thickly populated coastal zone of Kerala, India is facing severe problems due to attach of high waves during the southwest monsoon. Systematic beach profiling at 5-km intervals was carried out along the 560-km stretch of the Kerala coast during the pre- and postmonsoon seasons in 1984. Beach volume changes were calculated at each profile station, and the erosional and accretional trends for the entire coastal tract were demarcated in a map. Total erosion along 55 stations is 1276 m{sup 3}/m, and accretion is 626 m{sup 3}/m, resulting a net erosion of 650 m{sup 3}/m. The general erosional and accretional trends were also found to coincide with diverging and converging littoral currents deduced from the wave refraction diagrams. Such study at periodic intervals will be highly useful for proper management of the coastal zone.
