dc.description.abstract |
Sri Lanka is an island nation endowed with a wide range of coastal resources, greatly
contributing to the Gross Domestic Product. Coastal erosion is a major issue related to the
beaches in Sri Lanka. In this regard, Ratmalana beach is critically important as a potential
tourism destination due to its proximity to the capital city and the accessibility to a coastal
railway station. To develop a beach as a tourist destination, it is importance to monitor the
beach profile changes and find out the remedial measures for erosion prevention. For such
a management plan, either hard or soft engineering solutions can be utilized. Out of the
soft engineering solutions, the most reliable solution is beach nourishment. In this research,
Ratmalana beach was regularly monitored and a numerical model was built by utilizing
the public domain of XBeach to model the hydrodynamics in the area. Finally, two
nourishment scenarios were modelled, and the optimum nourishment scenario is
determined. Beach profile monitoring and calculated sand budget indicates that there is
significant erosion during the stormy weather season. Based on grain size analysis,
Ratmalana beach has a broad grain size distribution. According to the modelled
nourishment scenarios, profile nourishment has shown better performance. |
