Nutrient Dynamics in tidally-influenced coastal aquifers.

Coastal aquifers are increasingly becoming contaminated with nutrients due to growing populations and developments in coastal areas. Discharge of the groundwater along the beaches and through the seafloor is an important transport pathway of nutrients to coastal waters. The chemical composition of this submarine groundwater discharge depends on the landward freshwater sources as well as on the rates of groundwater flow and the biogeochemical reactions that occur in the subterranean estuary. The biogeochemistry of nutrients in subterranean estuaries and the groundwater nutrient fluxes to coastal waters have already been studied. But, previous studies have not considered the tidal effect which creates an important mixing and reaction zone in the near shore aquifer that may significantly reduce the concentration of discharging nutrients. Transport of contaminants to coastal waters through submarine groundwater discharge can lead to significant degradation of receiving coastal ecosystems. Moreover, the nutrient dynamics in the subterranean estuary can effectively contribute in the removal of such contaminants to some extent. Therefore, there is a need of studying the fate of contaminants released into near shore marine environments. The ultimate goal is to develop a numerical model to simulate the tidal effect on the natural attenuation of subsurface nitrogen and phosphorous prior to their discharge into the marine environment and to understand the nutrient dynamics in tidally-influenced subterranean estuary.

Personal Background

Nawrin completed her Bachelor of Science in Civil Engineering from Bangladesh University of Engineering and Technology (BUET) in October 2009. During the last year of her undergrad program, she chose Environmental Engineering as her major subject as she was always concerned about the environmental issues worldwide. After her graduation, she worked as a lecturer at The University of Asia Pacific, Dhaka, Bangladesh. She has always felt a concern about the global environmental changes around the world and subsequently realized that she wants to enhance and fortify her knowledge in the Environmental field so that she can contribute to some extent in the environmental challenges in Bangladesh and around the world. Nawrin joined the RESTORE group at Western in May 2010 as an MESc student which opened up a vast field of knowledge, opportunity and challenge in front of her.
