Monitoring and modelling of ecosystems

It is important for area management authorities and govDelft3D-Flexible-Mesh-D-Water-Quality-Western-Scheldt_570x366_acf_croppedernment bodies to gain a solid understanding of the correlation between soil, water, the ecology and climate. Our ecosystems are coming under more and more pressure as a result of worldwide population growth. Monitoring and modelling can be effective tools for quantifying the consequences of human activities for water and soil quality. In addition, they are essential instruments when it comes to evaluating which measures are most cost-effective.

More people, more environmental issues

hierdense beekGlobal population growth and the rising demand for raw materials are putting increasing pressure on ecosystems. Due to the effects of the present climate change, it is uncertain whether the benefits known as ecosystem services will all remain available for the next generation. These benefits include, for example, clean water, food, energy and climate regulation.

A cohesive solution for different issues

We will only be able to resolve the issues that develop within our ecosystems if we have good insight into the correlation of soil, water, sedimentation and the ecology. This explains why when it comes to developing solutions, it is necessary to involve numerous stakeholders and experts. To optimise this process, Deltares provides combinations of data systems, models and measuring techniques so that all relevant information is presented in a clear overview. This allows us to take the interests of all stakeholders into account and forms an objective means to ‘zero in’ on the most efficient solution.Passive samplers in peilbuis voor grondwaterbemonstering

New measuring techniques

New measuring techniques – including satellites, drones, sensors and passive samplers – present new opportunities to identify issues and evaluate the chosen solutions. For example, the continuous measurement of water quality and ecological conditions can also be utilised in real-time information and prediction systems. This allows water management authorities to provide a swift response to calamities and changing circumstances.

Identifying and resolving environmental issues

Around the world, public authorities and advisers rely on Deltares’ expertise to identify, resolve and prevent environmental issues. Newly acquired knowledge makes it increasingly easy for us to quickly, economically and effectively flag and explain changes in our ecosystems. We offer a variety of options in this context:

  1. Free, open source data systems, models and measuring techniques
  2. Knowledge and analyses relating to chemical and ecological processes on the intersection of disciplines (including ecology and morphology), hydrological compartments (e.g. groundwater and surface water) and system boundaries (‘from site to sea’).
  3. Measurement strategies and technologies that allow the user to measure possible pollutants in soil and water samples and determine which risks they may present.

In this context, we focus on nutrients, pesticides and new materials like nanoparticles, micro-plastics, human and veterinary medicines and drugs.
