Assessment of coringa mangrove shoreline migration using geospatial techniques /
(Taylor & Francis, 2020-11-06) Sharma, Garima; Patnaik, K.V.K.R.K.
Coringa Mangroves in the Kakinada Bay have evolved as the second-largest mangroves in the East Coast of India over the last century. The Coringa Mangrove shoreline has accreted considerably in the past decades as observed from the satellite imageries, adding value to the natural biodiversity of flora and fauna. This study is focused on quantifying the long term changes of Coringa mangrove shoreline using the Landsat imageries for years 1977, 1988, 2000, and 2013 using the Digital Shoreline Analysis System. For a mangrove shoreline length of 20.5 km, 41 transects were cast at an interval of 500 m for calculating the change and their migration distance using three statistical methods, namely End Point Rate (EPR), Net Shoreline Movement (NSM) and Linear Regression Rate (LRR). Results showed that there was considerable growth of mangroves in the bay leading to the seaward migration of the mangrove shoreline from the year 1977–2013. The study observed the difference in the mangrove shoreline migration dynamics in the South-eastern (near the bottom of the spit) and the western part of the Kakinada Bay. The calculated average degradation rate due to erosion is −5.19 m.yr−1 and the average accretion rate leading to their growth is 14.83 m.yr−1 for all transects of the 20.5 km mangrove shoreline stretch during this period. The results hold importance as they help in identifying the regions prone to mangrove degradation and enable management planning for the protection of the eroding stretch of the mangrove shoreline.
Hull capacitance: the unconventional green fuelling technology harnessing plug power navigate concept for inland waterways navigation
(SNAME Maritime Convention 2014, 2014-10) Shantanu; Sharma, Garima; Shukla, Kanishk Agyay; Bhaskar, Vidyut
With the huge increase in global liquid fuels usage, an alarming situation has risen to develop and adopt alternative green technology to mitigate global warming attributable to high pollutant emission. Transportation sector, being one of the major fuel and energy consumers, effective substitution is required for Inland waterways over land and rail transport. This paper focuses on the development of a ‘Plug Power Navigate’ concept to bring out an infrastructure to utilize the offshore wind and solar platform generated electricity for Inland Vessels navigation. Solar energy, available wind etc. can massively save fuel and keep environment pollution free. Technology like Wind and Solar resource assessment, wind energy installations, have been studied in this paper based on the climatic and technological sophistications. One of the major technological sophistications include, storage of this energy on board as Hull Capacitance. To harness the concept of Plug Power Navigate with the above mentioned technological sophistications, the vessel has been modified to accomodate the power storage facility on the principles of Hull Capacitance. It is based on the acquisition of power by means of an external source and its storage within the hull frame work, which can then be utilised later, for the purpose of navigation. The structural frame work is modified in compliance with the safety norms. Care has been taken to make minimal modifications to the hull structure from both safety and operation point of view, keeping the operation perspective unhindered. The inception of greener technologies in the shipping strata can be boosted by the tapping of renewable sources of energy along with the inclusion of power storage sophistications, and this debut in the maritime sphere can act as Pole Star for future research and exploration of various technologies in this direction bringing out an innovative set up for the Inland Water Transport worldwide.

Studying nexus between green technology fuelling and inland water ways upshoots in diminuting carbon emissions and conserving non renewable fuels
(International Journal of Science and Research, 2015-06) Shantanu; Sharma, Garima
With the huge increase in global liquid fuels usage leading to global warming due to high pollutant emission; an alarming situation has risen to develop and adopt alternative green technology. This is highly required for transportation sector, one of the major fuel and energy consumers. Inland waterways can be a potent replacement for land and rail transport. IWT dwelling on marine diesel and heavy fuel oil is required to adopt renewable sources of energy to be a competent mode of transportation. Green Technology focusing on alternative sources of fueling in the IWT ‘s efficient multi modal transport system will be the most certain a breakthrough in the IWT which already shares an advantage on all sections of transport in terms of fuel, cost, carrying capacity etc. This paper highlights various green oriented strategies for improving transportation practices through Inland waterways sustainably. We have explored scope of renewable energy like Solar, Wind, etc. for IWT in India where IWT is carried out only 0.2%. India blessed with huge number of rivers can potentially rely on Inland water transport, and utilization of enormous Solar energy, available wind etc. can massively save fuels and keep environment pollution free. Methodology like Wind and Solar resource ssessment, wind energy installations, Wave energy utilization, feasibility study of other alternative sources of fueling based on the climatic, technological sophistications like fuel cells, LNG, etc studied in this paper to harness renewable sources of energy can act as Pole Star for future research and exploration of various technologies in this direction bringing out an innovative set up for the IWT worldwide.
