Aeolian sand transport and its effects on the stability of Miramar-Caranzalem beach

G.V. Reddy, J.S. Sastry


Removal of sand by wind from the beach at Miramar-Caranzalem, Goa, has been found to effect its stability over a relatively longer time scale. This aeolian sand transport has been computed for this strip of the beach utilising the relation between the rate of sediment transport, the sediment and wind characteristics. The winds recorded at Panaji for the period 1969-1973 have been analysed and discussed for the directional transport of sand from the beachface. During fair weather months, the diurnal, inland, aeolian transport has been found to be nearly 180 m3 per km. length of the beach subjected to 10 m/sec, winds lasting for periods of approximately 8 hrs. a day. The resulting transport and its effects on the stability of this beach has been discussed
