Netherlands – Foreign affairs and other services – Building Flood Resilience with Nature Based Solutions in Tula River System, Mexico

Mexico is seeking to transition toward a modern flood management model that integrates controlled flood zones, restored floodplains, and nature-based solutions, following recent events that have exposed the limitations of traditional grey infrastructure. In this context, the Tres Culturas corridor in the Tula River basin presents a unique opportunity to demonstrate this shift in practice: a designed floodplain that reduces urban flood risk while generating ecological, cultural, and social benefits. Aligned with the restoration of the Tula River, one of the President’s 100 national commitments, the project has the potential to become a flagship success case and catalyze large-scale transformation in flood management across Mexico. To realize this opportunity, this assignment aims to contract a single qualified party, a principal contractor–subcontractor structure, or a consortium to provide technical and operational advice for the design of nature-based solutions addressing the hydrodynamics of the Tula River in the Tres Culturas Corridor. The core of the assignment will be to transform modelling data (provided by Inter American Development Bank -IDB-) into a safe, implementable and institutionally supported design, ensuring measurable reductions in flood risk while integrating long-term environmental and social co-benefits.
