Item Nondimensional methods to classify the tidal inlets along the Karnataka coastline, west coast of India(2019) Amaranatha Reddy N.; Mendi V.; Seelam J.K.; Rao S.This classification of tidal inlets is essential to maintain the stability of the inlets as well as to study the changing patterns of tidal inlets in India. Tidal inlets around the world have been classified as either wave-dominated or tide-dominated or river-dominated, since the 1970s. Tidal inlet classification for 471 inlets along the coast of India was carried out by Vikas M et al., based on wave and tide information. But only 30 inlets were considered for river-based classification due to lack of discharge information. In order to consider the river-based classification, the river flood discharge was estimated using Synthetic Unit Hydrograph (SUH) methods for Karnataka coast. In this study, 29 tidal inlets along the coast of Karnataka are selected for the classification based on river discharge. The classification has been done in two aspects; without considering wave period (Formula Presented) where Qtide is peak tidal discharge, Qf is river discharge and H is wave height. The results obtained are validated with hydrological and geomorphological classifications and the dominant forces over the dynamics of the inlets are determined. © Springer Nature Singapore Pte Ltd. 2019.Item Tidal energy estimation of potential tidal inlets along the east coast of India(2019) Mendi V.; Amaranatha Reddy N.; Seelam J.K.; Rao S.The power consumption is increasing with modernization of infrastructure and with the depleting fossil fuels. The need to look for alternate sources of energy generation has already reached a peak. The production of power from renewable energy sources is considered to be on a large scale in the near future because of the abundant sources across the country. One of the most reliable sources is the tidal energy as it can be extracted both by kinetic and potential means at the tidal inlets. The process of extracting tidal potential energy by storing the water during the high tide and release during low water is a well-established method. However, there are many parameters that are to be considered for the potential energy extraction. Two such important parameters, i.e. tidal range and basin area are considered in this study. The interrelationship between these two parameters and its overall influence on potential tidal energy estimation is studied. Along the four coastal states, excluding the Gulfs, around 250 tidal inlets have been identified (Vikas, M.Tech. thesis, 2015 [8]). Considering the standards of existing tidal power plants, tidal energy sites for energy extraction are estimated and will be presented in this paper. © Springer Nature Singapore Pte Ltd. 2019.
