![]() ![]() ![]() In addition, the IDPT can create so-called dredging suitability maps, which indicate the advised maximum turbidity production given a specific maximum allowable ecological effect. The tool in its present form has been developed for Singapore, but can serve as an example for applications elsewhere. The results of this assessment are clearly visualised, along with other project-relevant data, on an interactive map which can be used for communication with stakeholders and other interested parties. ![]() The Interactive Dredge Planning Tool enables (initial) assessments of the spreading of dredging-induced turbidity plumes and their environmental effects. The IDPT is developed based on the Interactive group modelling – MapTable concept. The Interactive Dredge Planning Tool (IDPT) enables the user to make a rapid quantitative assessment including the newly developed knowledge on ecological response to (dredging-related) sediment stresses. However, time hardly allows for a detailed (modelling) study to assess the environmental effects of different work methods already in the tender phase. In particular during the tender phase of a project. General concept of the Interactive Dredge Planning Tool (IDPT)ĭredging operations can be optimised in terms of environmental impact by assessing these effects before commencement of the work. The effect of this increased turbidity and sedimentation on the ecosystems is site and species specific, but has been addressed for certain species in Singapore in different projects within the Building with Nature programme. locations, species and species tolerance information. For this, the IDPT makes use of rapid assessment dredge plume modelling, a database with computed hydrodynamic background conditions and a database with ecological information, i.e. The Interactive Dredge Planning Tool (IDPT) is able to perform a rapid assessment of the expected, initial ecological effects caused by interactively defined dredging operations. Dredging and other human activities resulting in increase in turbidity levels and sedimentation rates may impact coastal ecosystems such as coral reefs and sea grass meadows. ![]()
