Quick model set-up using open databases (DelftDashboard)

Type: Software

Project Phase: Initiation, Planning and Design

Purpose: simple and quick model set-up, linking of open databases

Requirements: Basic modelling skills, knowledge on relevant environment

Relevant Software: Matlab or Matlab compiler if used as stand-alone tool

About

Although all surface water modelling efforts tend to be unique, a large number of steps (i.e. data collection, grid set-up, generating forcing, boundary and initial conditions) are the same in every modelling exercise. The main purpose of Delft Dashboard is to make it easier for modellers to go through these steps and enable quick model set-up anywhere in the world. It does so by linking to open databases for bathymetry (e.g. GEBCO, Vaklodingen, SRTM), shorelines and tidal data (e.g. TOPEX Poseidon). Users are enabled to add their own (classified) datasets to the tool. Delft Dashboard offers a large number of generic routines and handy toolboxes, such as coordinate conversion, bathymetric interpolation, nesting, domain decomposition and modelling of tsunamis and tropical cyclones. With these tools, setting up a model is a matter of minutes, whereas it used to take days or weeks before.

How to Use

The General User Interface (GUI) of Delft Dashboard is intended to be rather intuitive in order to enable a wide range of users to use the software. Nevertheless, some affinity with surface water modelling (especially with Delft3D) may come in handy for using the tool to its full extent. The model set-up can be drawn on a world map and changes in model lay-out or attributes are visualised to provide users with direct feedback of their actions. In default mode Delft Dashboard uses default values for the model settings, which makes it easy to set-up a working model. Of course these values can be changed to the user's preferences. Please note that quickly setting up a working model, does not provide any guarantees about the quality of its results.

Practical Applications

General Applications

Delft Dashboard has been and is still being applied especially in coastal modelling efforts, ranging from simple initial explorations to generating boundary conditions for 3 dimensional models and modelling of tsunami's and tropical cyclones. Below the minimal steps for setting up a tidal model using the Model Maker Toolbox are explained.

Building with Nature applications

As mentioned before Delft Dashboard is being applied in the showcase for the Interactive Dredge Planning Tool. Furthermore, Delft Dashboard is potentially useful to set-up models for any type of MapTable application.

Another practical application is for the assessment of shoal nourishments. The main purpose of this application is to quickly evaluate the effect of a shoal nourishment in areas where structural erosion of shoals leads to loss in intertidal area and important ecological habitats. It enables a fast comparison of different nourishment strategies or designs, particularly in the initial or tender stages of a project.
