Aquatic systems, including wetlands, estuaries, rivers, and lakes, provide ecologically and economically important services for the communities that surround them. These human and natural systems are tightly coupled, and development pressures have led to significant degradation in aquatic ecosystems over the last century. Opportunities are increasingly sought to recover lost ecosystem services through restoration and to harness ecosystem benefits by implementing green infrastructure designs inspired by natural and nature-based features (NNBF). This multidisciplinary session welcomes studies related to aquatic restoration or design of NNBF, including (1) development of novel strategies and best practices for “successful” restoration and/or green infrastructure design (e.g. design of reef restoration, living shoreline or bank protection, floodplain storage), (2) biogeochemical or hydrodynamic impacts of implementation (e.g. flow alteration, wave buffering, carbon sequestration), and (3) scientific advances leading to high-fidelity predictions of outcomes related to these investments (e.g. ecosystem modelling, site or species selection, benefit valuation).
