Rather than fully investigate each individual flooding incident, we will review the catchment as a whole, looking at the root cause of problems to find more cost-effective holistic solutions.
Once problems are defined and prioritised, we will evaluate the risks by producing a 2D model to better understand the most critical locations and assess impacts on the surrounding sewer network. We will then develop solutions: short-term mitigation measures for the worst affected areas, and long-term interventions designed to address underlying root causes.
Our study will bridge the gap between a drainage area planning model and the flood investigation process, highlighting ways of maximising the use of existing capacity and leading to more joined-up thinking during the design and development of interventions. Rigorous cost-benefit analysis will lead to buildable, more accurately costed solutions that deliver wider societal and environmental benefits.
