1. Interactive Tool Coastal Intervention: application Holland Coast
An interactive design tool has been developed to get an indicative insight in effects of measures on long term coastline development. The tool was developed for the Dutch sandy coast, the Holland Coast. A coastline model (in which the various hydrodynamic processes are numerically modelled) has been developed and linked to a web viewer for the Holland Coast. Mega nourishments, maintenance nourishments, groynes and revetments can be drawn in a map in this web viewer. Thereafter, the coastline model computes the indicative effects of these measures on coastline development in a few minutes. All stakeholders can see the effects of their design ideas directly in the web viewer.
In Coastal Workshop sessions with multiple stakeholders, this interactive tool has been used to support the development of alternative visions for the Holland Coast in 2100.
The application of the MapTable concept and tool application in this setting has resulted in:
- a fast and plausible estimate of morphological effects of various coastal interventions;
- interactive visualization of results by presentation using Google Earth.
During the sessions it was learned that participants were very keen to participate in the interactive process. They were motivated to come up with various alternatives and to understand the processes and resulting effects.
More information on the tool application can be found on the page of the Interactive Design Tool – Holland Coast.
2. Interactive River tool: application Dutch Rivers
MapTable tool applications have proven its use in several Dutch ‘Make Room for the River’ projects. During meetings with stakeholders, effects of measures, like a side channel, a floodplain excavation and relocation of levees, have been estimated with the help of MapTable. For these projects, the hydrodynamic model WAQUA was plugged into the MapTable tool application.
3. Interactive Dredge Planning tool: application Singapore
Nowadays static dredging criteria are used to avoid ecological damage. Aim of this study was to use ecologically relevant criteria instead of static dredging criteria for the assessment of dredging activities. Therefore, a dredge plume modelling tool has been developed for the waters around Singapore. This tool can make rapid assessments on the effects of dredging operations on vulnerable coastal ecology. A dredging operation can be planned on a digital map and users can specify the characteristics of this dredging operation. The tool will make a quick assessment of the expected plume dispersion and stressor intensity at relevant locations. Furthermore, this stressor can be translated into an expected effect on ecology by adding others tools on Species Responses (e.g. for seagrass) . Users can optimise their proposed dredging operation based on this quick assessment of the ecological impact.
More information can be found on the Tool page of the Interactive Dredge Planning Tool Singapore. A tutorial on the use and a guideline about the setup of the Interactive Dredging Tool are under development.
4. Interactive O&M tool: Streamline tool
The aim of the Stroomlijn project is to optimise the maintenance of floodplain vegetation, because high vegetation can affect extreme water levels in rivers. A MapTable tool application has been applied to evaluate maintenance strategies in this project.
