You will be responsible for:

  • Working alongside recognised experts across a range of disciplines to delivering challenging modelling projects.

Job Profile

With the ongoing and future impact of climate change, demographic trends and the increasing regulation to protect the environment, there is an increasing need for river modelling to verify water quality compliance and to advise on potential mitigation. We have an excellent track record in supporting UK water companies in these studies and we have developed innovative modelling approaches to do so. Our expertise also expands to cover coastal water quality investigations, source apportionment assessments, catchment management modelling and the application of nature-based solutions to tackle pollution.

We have secured major AMP7 frameworks with most UK water companies, and we have a global reach to support regulators, asset owners and investors worldwide. This means that demand for these services continues to grow, and in response to this we are keen to engage a talented river water quality modeller to support our project delivery and to collaborate in our digital initiatives in the field.
