Flood Forecasting Model

Gisborne District Council (Council) require development of a modern forecasting system for the purpose of informing emergency preparation and response. Council is looking to replace its existing in-house flood forecasting model Adaptive Rainfall Runoff Warning System (ARROWS). ARROWS is used to inform real-time decision-making during weather events and provide early warning of flooding, its replacement will also be utilised for this purpose. We seek to engage a credible provider who has capability, experience, capacity and a strong track record in flood forecast modelling to assist with the replacement of ARROWS.
Council is providing this opportunity to:
• service providers with available resource to deliver in 2025. We have a deadline of 30 June 2025 from our funder, but we are open to feedback from the market regarding the feasibility to deliver this project by this date;
• service providers with a proven capability; and
• service providers with experience in suitable flood forecasting software packages and platforms.
