Flood & Coast 2026: RisKma Real‑Time Flood Forecasting Session

Flood risk is increasing worldwide due to climate change, urbanisation, and more frequent intense rainfall. Effective flood risk management relies on timely, accurate information and decision‑support tools that enable proactive rather than reactive responses. At Flood & Coast 2026, we introduced RisKma, a real‑time flood monitoring and forecasting platform developed through collaboration between CTI Engineering (Japan) and Waterman (UK), and explored its use in UK surface water flood management.

RisKma is a web‑based platform that integrates forecast rainfall, water‑level data, sensors, CCTV imagery, and real‑time hydraulic modelling within a single interface. Updated every 15 minutes, it provides advance warning of flood risk, visualises predicted inundation pathways, and stores simulation outputs for post‑event analysis. The platform is widely used by public authorities and developers in Japan, where fast, reliable flood response is essential.

We shared insights from a UK pilot with Warwickshire County Council, focused on surface water flood risk in locations where traditional defences are not viable and Property Flood Resilience (PFR) is often the primary mitigation option. The pilot examines challenges around accuracy, consistency, cost, and community confidence when issuing flood alerts. Its aim is to demonstrate how real‑time forecasting can improve warning reliability, support emergency decision‑making, and reduce anxiety in flood‑affected communities.

Through a live demonstration and early findings, this session highlighted the value of international knowledge exchange, digital innovation, and cross‑organisational collaboration in strengthening flood resilience across the UK.
