The Oku-Kom highland morphological and human stronghold of West Cameroon with rich volcanic soils has attracted farmers and breeders thereby rupturing the mountain ecological equilibrium through slope gulling and mass movements. Overwhelmed, the indigenes adapted unsuccessful regreening approaches but without slope gradient considerations.

The Farakka Barrage Project on river Ganga, commissioned in the year 1975, mainly for diversion of 1135 cumec flow of water from river Ganga to river Hoogly through Bhagirathi, for the preservation of Kolkata Port. River Ganga due to its meandering nature is causing bank erosion problems not only in the vicinity of barrage but also in the reaches for upstream and downstream of the barrage.

Study of beach morphological changes during monsoon and development of capabilities towards its prediction is of vital importance in coastal zone management. A study of the beach erosion/accretion processes during south-west monsoon and its numerical modelling is attempted in this communication for a micro-tidal and high-energy beach. Comprehensive
