About Kevin Ouwerkerk
Kevin is committed to resilient and healthy water systems as a researcher and consultant at Deltares. His expertise lies at the intersection of data analysis, water quality, and ecotoxicology, where he makes a significant contribution to a more sustainable environment for both people and nature.
In various projects, such as the Emission Registration and the National monitoring network for nutrients in agriculture dominated headwaters, Kevin uses data to generate valuable insights. He ensures that these insights are accessible to others, enabling better decision-making regarding Resilient and healthy water systems.

Value and limitations of Machine Learning in high-frequency nutrient data for gap- filling, forecasting, and transport process interpretation
High-frequency monitoring of water quality in catchments brings along the challenge of post-processing large amounts of data. Moreover, monitoring stations are often remote and technical issues resulting in data gaps are common.

Many aquatic ecosystems in densely populated delta areas worldwide are under stress from overexploitation and pollution. Global population growth will lead to further increasing pressures in the coming decades, while climate change may amplify the consequences for chemical and ecological water quality

Projects
Step-by-step plan for optimization of high-frequency water quality data Optima-HWQ
Optima-HWQ stands for Optimal High-frequency Water Quality. Our focus is twofold: on one hand, the near real-time detection of anomalies for improved online visualizations and adequate sensor maintenance, and on the other hand, the retrospective optimization of data series.
Nederland, September 2024NORMAN prioritisation of Dutch water quality data
The chemical industry is rapidly developing new substances, which are used in a variety of products. Some of these substances end up in the environment. From the prevention principle, it is preferable not to discharge any substances (zero pollution), but prevention has the highest priority
