The study found that some of the Indian deltas — Brahmani delta in Orissa, and Godavari and Mahanadi in Andhra Pradesh — are at a greater risk as to the rate of sediment Aggradation (raising the level of the delta through sediment deposition) no longer exceeds relative sea-level rise.

While there are no Indian deltas in the peril category (where the Aggradation and compaction of the delta sediments overwhelm the rate of sea-level rise), the Krishna delta in Andhra Pradesh falls in the last category of greater peril.

In the case of the greater peril category, the deltas have virtually no sediment deposition (Aggradation) and/or have very high accelerated compaction of sediments.

Here the relative sea-level rise is about 3 mm per year. The maximum relative sea-level rise of 13-150 mm per year is seen in the Chao Phraya delta in Thailand.
