Sediment Management For UDA Framework.

This research note highlights the importance of developing a UDA Framework for Sedimentation Management. It suggests that Sedimentation Management is a large-scale multilevel problem and requires cooperation from different stakeholders to avoid fragmented approach and formation of policy. Further, it provides various methods for application of Sedimentation Management such as Water resource management, Port management, Inland Water Management and Ecosystem Management. It recommends employing an effective and integrated system of sediment management in every water based project in the country.

1. India has 5,202 large dams and many more small dams and barrages, 111 inland waterways classified as ‘National Waterways’ (NWs) having 20,275 kms spread across 24 States and a coastline of total length 7516.6 km including mainland, Lakshadweep islands and Andaman.

2. There is high flow of water bodies due to concentration of annual monsoon in one quarter of the year causing excessive siltation. Thus, sediment deposition threatens the sustainability from both onsite and off site damages causing enormous costs to the national economy.
