Shoreline Management Plan (SMP)

Long-term monitoring of coastal processes has increased our understanding of how the coastal systems function in conjunction with how coastal protection and other structures interact with these natural processes. The advances in understanding of coastal process have resulted in the need for a long-term, strategic approach to coastal management.

The Karnataka SMP (draft)– a second generation of Shoreline Management Plans created by the Department of Public Works, Ports and Inland Water Transport, Government of Karnataka, break sections of the Karnataka coast down into beach management units based on natural sediment movements and coastal processes, rather than administrative boundaries. Strategic policy options for shoreline management considered are “No Active Intervention (NAI)”, “Managed Realignment” (MR), “Hold the Line” (HtL) “Advance to Sea” (AtS) and “Limited Intervention” (LI).

For each of those beach management units, the SMP presents how the area is protected or vulnerable today and whether those protection can continue to be maintained, or if they should be changed or even left alone in future. The SMP approach builds on our knowledge of the coastal environment, provides a large-scale assessment of the risks associated with shoreline evolution, sea level rise, coastal flooding and erosion and presents a policy framework to address these risks in a sustainable manner.
