The container port development in Sapangar Bay, Sabah, Malaysia, involves landfill reclamation in close proximity to coral reef, seagrass and mangrove habitats and existing port facilities. DHI has completed an environmental impact study for the marine components of a full detailed EIA, including field surveys of currents, water levels and bathymetry, marine and mangrove habitats. Numerical modelling of coastal hydraulics, water quality and suspended sediment plumes was also performed using DHI's MIKE 21 modelling system.

DHI's Rapid Impact Assessment Matrix (RIAM) analysis package was used as a transparent method for assessing and comparing the various multi-sectoral impacts on the environment. Mitigation measures were also formulated for potentially significant impacts, including the specifications for the environmental monitoring and management plan, which has subsequently entered the implemenation phase, becoming the first full feedback monitoring plan in Malaysia.
