Spotlight on Royal HaskoningDHV’s TRICO Approach

Royal HaskoningDHV’s TRICO approach has been selected for a pilot scheme investigating flood management for the 10,000 home Garden Town planned for Wisbech.

The pilot project also received the backing of the Dutch government with a 55,000EUR grant from their Partners for Water program which funds innovative water projects around the world.

Developed in partnership with Nelen & Schuurmans, Deltares and TU Delft, the Toolset for Rapid Interactive Collaborative Optioneering (TRICO) was awarded the innovation award in 2016’s Defra flood management and modelling competition.

The toolset uses revolutionary hydraulic modelling tool 3Di, and an interactive MapTable, to allow full stakeholder collaboration when developing flood management options.

Speaking of the project, Jaap Flikweert, Director of Water Governance and Strategy at Royal HaskoningDHV said: “Wisbech 2020 presents an extremely exciting but also extremely challenging opportunity for the area. Due to the new town’s location on the floodplain some exceptional and innovative approaches will need to be employed to ensure the development is safe and sustainable and gets consent. We’re delighted to have the chance to implement our TRICO on such a nationally significant project.”

“The Dutch government’s contribution from their Partners for Water fund will make an important difference to the pilot project. The magnitude of the flood management challenge is reflected in the close interest that will be paid to this pilot both regionally and nationally as the UK seeks ways to safely create new homes and communities and alleviate the national housing crisis.”


The pilot project has been commissioned by Fenland District Council and is supported by Anglian Water and as such the TRICO approach is a natural choice allowing as it does full stakeholder collaboration.

Taking inspiration from the Dutch approach to flood management the toolset also allows assessment of the social and economic value of flood solutions.

The approach utilizes 3Di, a next generation hydrological and hydraulic modelling tool which allows swift visualization and scenario testing, and allows solutions to be tested during live workshops with input from a range of stakeholders.
