WIT is the online management system for waterbed professionals. This digital management package supports the complete dredging process: from planning to implementation and all steps in between.

WIT's field application has been developed for collecting data in the field and recording progress during dredging. Thanks to the connection with GPS, work is carried out accurately. The data from the field is stored in a central database and is ready for further processing in the office.



WIT Metingen accurately maps the waterbed and surroundings. With this field application, data is collected and recorded uniformly and accurately. This ensures greater efficiency and high data quality.

- Sampling waterbed
- Measuring cross profiles
- Ecological quick scan
- Inventory of banks, structures and surroundings


WIT Implementation works via the app and a central information system via the computer. All parties involved (contractor, supervisor, manager and client) record progress, details, points of interest and agreements in WIT during the dredging work. This means everyone is always aware of progress and details.

- Pre-recording
- Recording progress of work
- Polls in and out
- Klic notification
- Weekly reporting


About the WIT system: A lot of data about the water system is collected in the process of preparing and carrying out dredging works. In WIT, this information is bundled and clearly presented per project phase. Different modules with useful functionalities have been developed for each phase. In WIT, the important information is stored sustainably, so that data once collected can be reused later in another work process.

In summary, WHITE is:
- User-friendly application for the management and maintenance of the water system.
- All data stored in one central database.
- Establishing a multi-year dredging maintenance plan.
- Digitally prepare, supervise and monitor the dredging process.
- Real-time insight into relevant waterbed information anytime, anywhere.
- Calculating scenarios and analyzing the current status and potential for biodiversity, for example.
- Storing all waterbed related data, area knowledge and experiences from the field.
- Communication platform within a dredging work with which condition, progress and details are recorded in images, status and notes.


The WIT app has been further developed for users of the WIT system. If you are interested in WIT, please contact us: [email protected]. To find out more first, take a look at our website: www.witsysteem.nl. WIT is a collaboration between Tijhuis Ingenieurs and Roos Geo Solutions.
