“…Balasubramanian et al 9) evaluated the sensitivity of the coastal zones in the eastern Ramanathapuram District, Tamil Nadu, India, by examining the shoreline changes of accretion and erosion 10) . More specifically, this study examined Mandapam, Pirappanvalsai and the surrounding villages of Pirappanvalsai and Enmanamcondam, as well as the towns of Nagachi and Terbogi.…”

Due to the increasing expansion of infrastructure, there is a very high worldwide demand for river sand in the modern era. India's annual demand for river sand is 60 million metric tons. In metropolitan cities, the need for river sand is about 1 kilogram per person per day. The rapid extraction of river sand is producing detrimental effects on the environment. The main objective of the research is to determine the impact of rapid sand mining on river bank erosion and accretion and to find substitute materials for river sand. The River bank variations were measured for 1990-2000, 2000-2010, 2010-2020, and 1990-2020, and the corresponding erosion and accretion maps were created. These materials (copper slag, quarry dust, foundry sand, and sawdust) are used as an alternative to river sand to produce concrete mix. These alternatives substituted river sand from 10% to 60% in the mix proportion of M25 grade concrete to obtain the optimum compressive strength. These alternatives were also subjected to physical testing to determine their similarities to river sand. A Scanning Electron Microscope was used to analyze the hardened concrete's microstructure. The hardened concrete (River sand Substituted) is also analyzed to determine the changes in the internal structure of the concrete after 14 and 28 days.

“…Yu et al (2019) proved that there is a high spatial coupling between spaces with high levels of vitality and actual aggregation of activities using the open-sourced big data of streetscape images. Besides, there are also studies utilizing geographical information systems (GISs) to classify and identify coastal zones based on high-precision satellite maps (Balasubramanian et al, 2022;Thirumurthy et al, 2022).…”

Success in delivering dynamic urban coastal zones is considered essential, as it brings enormous opportunities to the social, economic, ecological, and cultural development of the cities in addition to benefitting the coastal zones. However, the environmental drivers contributing to urban coastal zone vitality remain uncertain due to unclarified spatial boundaries and the influences of diverse characteristics from surrounding contexts. This study aims at exploring environmental drivers that can vitalize urban coastal zones and can inform an effective way to instruct design procedures. It sets out from clarifying the spatial boundaries of urban coastal zones and emphasizing the mutual connections among its spatial components. A data-driven multi-method approach is used to analyze spatial forms, traffic organizations, land uses, landscape characteristics, and coastal functions of the eight typical coastal cases selected in different countries. Results suggested that six typical coastal zone types can be classified based on landscape characteristics and coastal functions, while the other vitality-related aspects, spatial forms, traffic organizations, and land uses are analyzed to imply design requirements for each type. It is found that requirements on vitality-related aspects of the six types evidently vary with the coastal functions, but there are similarities among the types with similar landscape characteristics.
