The Water Levels app is an app that let you visualize the water levels and tidal range of the Schelde Estuary.
The app was created for ScheldeMonitor by the Flanders Marine Institute.
Data for this application is retrieved yearly from ScheldeMonitor's databases, through a webservice URL from the ScheldeMonitor's toolbox.


The visualized data is made available by ScheldeMonitor under a CC-BY license (More info). Please reference data and products as:

ScheldeMonitor Team; VNSC Werkgroep Onderzoek & Monitoring (2020). Data downloaded from ScheldeMonitor:
a data portal with information, data and products on the Scheldt Estuary. Accessed at (insert date) through the data analysis platform.

Plots, maps and charts.

From the left navigation panel you'll be able to access data for the parameters: high tide, low tide, tidal range and percentil99.
All plots, maps and tables in this application are interactive. The visualized parameter, the number of stations, the time range and the distance to Vlissingen can be adjusted by using the sliders in the left menu.

For a quick walkthrough have a look at the video below.

Data availability

Behind this application is a fixed dataset that was complied from the raw data associated with the T2020-report. For the Test Parameter 'Hoogwater', the high tide levels in the period 2010-2015 are available for 14 stations in the Netherlands (Weterschelde, source Rijkswaterstaat) and 19 stations in Flanders (Zeeschelde and its atributaries, source Waterbouwkundig Laboratorium). For older years, data associated with the T2009-rapport Schelde estuary was used. Data from 14 Dutch and 37 Flemish stations was analysed.

Due to maintenance / saturation and malfunction, there are gaps in the data of the Dutch station Schaar van de Noord (SVDN) in the years 2013, 2014 and 2015. No measurements are available for 2014 for Borssele station (BORS). For Europlatform station (EURO) all measurements are missing in the year 2011. The data for other station is complete.

Interactive apps in ScheldeMonitor

These applications are created and maintained by VLIZ, using R and RShiny programming. Visitors can use the apps to interactively create graphs and figures about nutrients, water levels, wave levels and species distribution in the Scheldt estuary. The apps are momentarily only available in dutch, but will receive an english version in 2023.
