Dynamic Coastal Flood Risk Prediction Model

Develop a scalable, machine learning-driven framework that integrates multi-modal Earth observation data, historical meteorological datasets, and real-time oceanographic observations to deliver coastal flood forecasts with a 48-hour lead time. The solution should incorporate international standards, interoperable data formats, and robust validation protocols to ensure reliability and scalability across multiple coastal regions.

Coastal flooding is among the most costly and frequent natural disasters, intensified by climate change and rapid urbanization. Current forecasting methods often lack the precision, granularity, or timeliness required for proactive response measures. To address these limitations, the proposed solution will utilize open data standards such as the OGC (Open Geospatial Consortium) Web Map Service (WMS) and NetCDF conventions, as well as widely recognized hydrodynamic modeling frameworks. By combining advanced machine learning algorithms—trained on historic flood events—with real-time observational data streams, this initiative aims to produce a predictive model that meets the stringent requirements of emergency management and infrastructure protection.

The resulting predictive system will leverage state-of-the-art AI frameworks (e.g., TensorFlow, PyTorch) and follow geospatial data standards (e.g., ISO 19115 for metadata, ISO 19128 for web map services). It will provide coastal cities with a robust decision-support tool for preemptive action, enabling emergency planners to deploy resources more effectively. The implementation will be fully documented with industry-standard practices, including model validation procedures, data source integration workflows, and API specifications for seamless integration with existing disaster management platforms.

Target Outcomes:

• A machine learning model validated against multi-year flood data records with at least 90% accuracy in event prediction.
• Compliance with OGC standards for geospatial data dissemination and ISO frameworks for data quality.
• A comprehensive open-source deployment package including Docker containers, RESTful APIs, and CI/CD pipelines.
