One of the major tasks of Flanders Hydraulics Research (FHR) is to examine the water levels of navigable rivers. Our primary objective is to manage water volumes as efficiently as possible. Too much or too little water can cause serious problems for citizens, the navigation and the industry. Through thorough research we can predict critical situations and formulate appropriate measures.
The Hydrological Information Centre (HIC) carries out the operational activities. This team is responsible for field measurements. They collect and process data on precipitation, water levels, flow rates and the amount of sediment in the water. Inform the public and the watermanagers of the navigable waterways about crucial situations.

This site provides measurements and forecasts of:
These measurements provide interesting study material. We turn this data into mathematical models which we then use to simulate situations of water shortage or flooding. By doing so we can give realistic advice on how to manage these problematic situations in an appropriate and effective manner.
- collects info on precipitation, flow rates, water levels, sediment volume based on field measurements;
- stores and manages these data in the WISKI database;
- makes predictions about water levels and discharges based on these data;
- informs the public and the watermanagers about extreme situations.
Our HIC team works on projects on:
- updating the website www.waterinfo.be. This site provides info on the water levels in Flemish waterways.
- management and validation of the measured data;
- forecasts of water levels and discharges based on these data and numerical models;
- the dissemination of this information to the administrators of the Flemish waterways, citizens and official bodies.
During long periods of drought a shortage of water occurs in the rivers and canals. Flanders Hydraulics Research (FHR) is examining how the available water in the channels can be used in the most efficient way.
Through this research we can demonstrate which measures can be taken to minimize the effects of water shortage.
This way we work towards controlling the costs and practical implications of water shortage. At the same time we predict the effects of climate changes on water availability.
These strategies are based upon hydraulic and hydrological models which are developed in specialized software: MIKE11, MIKE SHE, MIKE BASIN
FHR contributes to the following projects concerning low water strategies:
- realise an action plan in case of water shortages in the Albertkanaal and the Kempische kanalen. This plan aims to formulate appropriate solutions for the different sectors (navigation, agriculture, industry, drinking water facilities, electricity generation).
- measures to deal with the impact of climate change on river flows and water levels;
- preparation of monthly low water reports for the period April to October.
Water management plans
The runoff behaviour of rivers and channels provides important information in assessing the impact of flooding. Flanders Hydraulics Research (FHR) develops computer models which can simulate this behaviour. This allows us to predict what effect interventions could cause on rivers. These models enable us to anticipate the impact of a flood in relationship to the discharge. Based on this information we can calculate the resulting damages. This way we actually contribute to managing the varying volume of water in our rivers and canals.
We participate on the European Directive on the assessment and management of flood risks to realise flood risk management plans in 2015.
These simulations are performed with computer models which were developed in various software: MIKE 11, MIKE FLOOD, MIKE SHE, DELFT 3D, LATIS, ...
FHR works on various projects related to water management such as:
- design of GGG’s and GOG’s which are planned in the new Sigma Plan;
- realisation of the Integrated Coastal Security Plan;
- optimization calculations for the weirs on the Dender;
- a method to determine the breach sensitivity of Flemish dikes;
- development of a softwaretool LATIS to determine damage- and risk analysis.
