Topic

As a result of climate change, we are experiencing more annual rainfall in Denmark and greater weather variability with more frequent and intense storms and rainfall events. The increased rainfall affects the interaction between surface and near-surface groundwater, shifting the balance that our systems are designed to handle.

Higher groundwater levels and more water on the surface challenge us both in open landscapes and urban areas. At the same time, the risk of flooding increases when even everyday rain can no longer be absorbed but ends up being stored, often in places that cause significant inconvenience and costs.

There are no integrated tools that correctly mechanistically describe the dynamics between different water domains on a scale relevant to sewers systems and building drainage.

The goal is to investigate the integration between two industry-standard systems, MIKE+ and MIKE SHE.

Relevance to DHI

The mode tool is used to calculate the effect of combined measures, including economic estimates. The implementation of selected measures can be combinations of new pipes, new drainage channels, re-designing of the pipeline network, Nature-Based-Solutions, etc.

This research idea is part of the on-going MUDP project - SAMVAND that DHI is collaborating with DTU Sustain, Aabenraa Kommune and Arwos.

What is the student's contribution

• Model configuration for coupling MIKE+ and MIKE SHE.
• Model implementation and testing of novel sustainable measures, eg. NbS, to reduce effects from high groundwater levels in urban areas.
