Abstract

fetched live from OpenAlex

Flooding remains one of the most frequent and damaging natural disasters, intensified by climate change and urbanization. High-resolution real-time flood depth observations at the urban scale remain spatially sparse, thus alternative data sources are required to support risk assessment and emergency response. This study introduces STURM-FloodDepth, a deep learning pipeline to estimate and map urban flood depths using street-level and oblique aerial imagery. The workflow consists of two sequential modules: A. flood depth estimation, proceeding through vehicle detection (YOLO-World and SAHI), contextual cropping, super-resolution enhancement (EDSR), and flood level classification (fine-tuned ResNet-50); and B. georeferencing and mapping, proceeding through orthographic reference image construction, feature matching (SuperGlue), homography estimation (RANSAC), geospatial projection and mapping, conversion and export to GeoJSON. The classifier achieved AUC values ranging from 0.78 to 0.98 across all classes. Real-world qualitative validation confirmed its accuracy in operational conditions. STURM-FloodDepth is a modular, scalable, sensor-agnostic tool for urban flood monitoring, with applications for urban resilience, disaster management, and smart city. The framework is released as an open-source tool to foster further research and operational deployments.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
