Hydrogeochemistry and spatio-temporal changes of a tropical coastal wetland system: Veli-Akkulam Lake, Thiruvananthapuram, India

Abstract: The backwater of Veli-Akkulam, adjoining the Arabian Sea in the south-west part of Indian Peninsula, is a coastal wetland system and forms an integral part of the local ecosystem. In addition to the usual marine interactions, this water body is subjected to anthropogenic interference due to their proximity to the Thiruvananthapuram City urban agglomeration. This paper showcases how an urban agglomeration alters wetland system located within a tropical monsoonal environment. Water samples from this lake togethe… Show more

“…Similarly, the Krishna and Cauvery rivers and their tributaries have also regained their decades-old poor status in respect of water quality ( KSPCB, 2020 ). This prompted us to launch a study of a tropical river, the Karamana R., in the southwestern seaboard of India hosting the capital city of Thiruvananthapuram in the state of Kerala, India, which is on a fast track of urbanization through the past four decades ( Sajinkumar et al, 2017 ). Hopefully, the outcome of this research will shine new light on the water quality in Karamana R., basin (KRB), especially against the backdrop of COVID-19 disruptions.…”

“…Floodplain wetlands providing enormous growth of fish food organisms are very much potential for capture fisheries as well as culture based fishery [25]. These natural landscapes with strategic importance to human society [25,26] have been facing threats from anthropogenic modifications [27], often leading to unbalanced floodplain conditions such as increased sedimentation and siltation processes; eutrophication through various anthropogenic sources [28,29]. Wetland hydrology plays very significant role to define its nature whether seasonal, dry or perennial [3].…”

“…Wetlands though act like a 'kidney of landscape' [34] but contaminated water can negatively affect wetland biota and ecosystem [10,35]. Thus, surface water quality of floodplain wetland can be determined by both the natural processes (precipitation rate, soil erosion, weathering processes) and the anthropogenic influences such as agricultural and industrial activities, urbanization and over exploitation of water resources [28,36]. High amount of sediments from the catchment area increases turbidity which affects wetland biota negatively [20,37].…”
