    Urbanization Challenges in Emerging Economies
    (American Society of Civil Engineers (ASCE) onlinejls@asce.org, 2017) Mendi, V.; Reddy, N.A.; Lokeshwari, M.; Raghavendra, T.; Seelam, J.K.
    Tidal inlet is an opening along the coast which facilitates the exchange of water and nutrients. The energy extracted at the tidal inlet using tides is called tidal energy. Tidal energy is reliable and not depleting. Since the density of seawater is 800 times denser than air, the energy extraction is much favorable and reliable resource. Because of the above said advantages, tidal energy production has become an important energy source at global platform. The study area chosen is the Sri Lankan coast. The tidal condition along the Sri Lankan coast is semi diurnal. Identification of the locations for energy extraction is important as the width of the identified inlet at the coast plays an important role in energy extraction. Also, parameters like tidal range, basin area have to be taken into account in order to consider the inlet suitable for energy extraction. In this paper, tidal inlets will be identified along the Sri Lankan coast, the data will be collected for the parameters that are required to consider an inlet for energy extraction and the potential energy that can be extracted at the inlets will be assessed. © 2018 American Society of Civil Engineers.

    Estimation of potential tidal energy along the West Coast of India
    (World Scientific, 2018) Mendi, V.; Seelam, J.K.; Rao, S.
    Tidal energy is one of the clean and non-depleting renewable energy sources. In contrast to other clean sources, such as wind, solar, geothermal etc., tidal energy can be predicted for years ahead. Also, the medium, seawater, is more than 800 times denser than air and the astronomic nature of the underlying driving mechanism results in an essentially predictable resource, although subject to weather-related fluctuations. These features make it an important energy source for global power production in the near future. There are various types of tidal power plants across the world with varying tidal elevation. Also the method of conversion of the tidal energy into electrical energy is site specific. For example, we can adopt conventional method to extract energy in high tidal regions. But when it comes to low tidal regions like the southern India where tidal elevation measurements does not exceed 2.5m, there is a need of low flow turbines which can extract higher energy from lower head. An important factor that is responsible for the velocity of tidal stream is the tidal inlet dimensions. In this paper, an attempt has been made to identify the feasible locations for extraction of potential tidal energy along the Indian Coast. © 2018 World Scientific Publishing Co. Pte. Ltd.
