Beach nourishment threats Sri Lanka's unique marine assets
Environmental Impact Assessment done or not?

The Marine sub-committee (MSC) of the Wildlife and Nature Protection Society (WNPS) has identified three distinct issues regarding the government’s recent beach nourishment programme in relation to its possible adverse effects on the marine environment.

MORE PERMANENT ALTERNATIVES NOT CONSIDERED

A beach nourishment programme commenced south of Mt Lavinia centred on the Kalutara Calido beach to restore severely eroded beaches. Action to correct observed erosion is considered necessary. Whether beach nourishment was the best option or not cannot be commented on as there is no information regarding any studies (modelling) of sand movement and the physical forces at work causing erosion.

There are a number of structures parallel to the coast that have been erected in the past to control erosion. These are seen from Panadura to Moratuwa and also many north of Negombo. The question arises whether any alternatives to beach nourishment of a more permanent nature were considered before the recent programme was initiated. We wish to point out that boulders, put in British times, effectively protect the shoreline. An excellent example is the stretch of beach between Kollupitiya station and the Wellawatte canal which has been thus protected for well over a century. Why has this practice not been considered for some areas at least?
