In 2014, the construction of the Green Square Storm Water Drain (GSSD) began by the City of Sydney, aiming to alleviate the flooding of Green Square. As a crucial part of the project, Abyss Solutions conducted a complete bathymetric (depth) profiling of the sediments at the canal floor. Data from this survey and a subsequent post commissioning survey, allowed Sydney Water to monitor sediment erosion and deposition rates along the canal and compared the results with previous modeling results, with a means of validating the hydraulic model and managing stakeholder concerns to the construction of infrastructure in an environmentally sensitive area.
