Dam construction facilitates

Sethusamudram Shipping Canal Project, when completed, will transform parts of the southern coromandal coast qualitatively. Since historical times, this portion of the coast (Palk Bay, Adam’s Bridge) is used only to fleets of small crafts involved in coastal trading and fishing.

Analysis of multi-date satellite sensor data and maps indicated loss of 1836 ha of land during 1976–2001 along the Godavari deltaic coast resulting in displacement of coastal communities and mangrove destruction. Decrease in sediment loads from an annual average of 145.26 million tons in 1971–79 to 56.76 million tons during 1990–98, apparently due to construction of dams, largely diminished vertical accretion at the delta, while continued coastal subsidence that might have been accentuated by possible neotectonic activity and consequent relative sea level rise led to shoreline retreat.

Hydrological characteristics and sedimentation loading in Hokersar wetland of Kashmir Himalaya was monitored from November 2000 to october 2001. The compound water budget showed a substantial (91 percent) input from various surface inflows and just 9 per cent through precipitation.

The Sethusamudram Ship Channel Project under the consideration of the Ministry of Shipping, Government of India, envisages creation of a ship navigation channel to suit different draughts (9.15 m, 10.7 m and 12.8m) through dredging/excavation in Adam’s Bridge, parts of Palk Bay and Palk Strait.

The Indo-Gangetic plains are drained by several fan and interfan rivers fringing the margin of the outer Himalaya. These fan and interfan river systems are distinctly different from each other in terms of hydrology and sediment transport and generate typical
