These transitional zones, characterized by the mixing of riverine and oceanic waters, foster an astonishing array of biodiversity and provide critical ecological services. From filtering pollutants to providing nursery grounds for various species, estuarine wetlands play an indispensable role in maintaining the health and balance of coastal regions worldwide. Despite their importance, these ecosystems face numerous threats, including habitat loss, pollution, and climate change impacts, underscoring the urgency for their conservation and sustainable management. Understanding the intricate interplay of biological, hydrological, and geological processes within estuarine wetlands is essential not only for their preservation but also for the broader resilience of coastal ecosystems and the communities they support.<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Estuaries stand as a crucial and unique element of the coastal scenery, featuring intricate
