SPOIL DISPOSAL PRACTICES IN INDIA

India, having a coastline of about 5,700 km and over 225 ports of different sizes, is faced with numerous problems relating to dredging and spoil disposal. The problems on the eastern and western coasts are markedly different from one another. The western coast exhibits a very flat sea bed, the slope varying from 1 in 500 to 1 in 1000, and the sea bed consists of mud, clay and silt with littoral movement being relatively unimportant. The major ports located on the western coast have very long approach channels involving large quantities of material for dredging and disposal. Disposal sites are 5 to 10 km away from the ports and with further deepening of the harbours these locations would need to be altered. On the eastern coast, due to the fairly steep bed slopes, the lengths of the approach channels are comparatively smaller than those on the western coast. But the very strong littoral drift necessitates a different approach to the problem of spoil collection and disposal. In the case of estuarine ports like the port of Calcutta on the bank of river Hooghly about 130 km inside the river mouth, yet a different aspect of spoil disposal has to be considered in view of the very long haulage. The paper deals with the experiences gained from the different ports in India and highlights the considerations leading to the choice of the disposal sites in different cases depending on the physical condition together with the role of hydraulic model studies in such instances.
