Floodops

FloodOps is a flood disaster response platform built for Kerala's flood-prone districts, connecting citizens, government officials, and volunteers on a single system from prediction, to verification, to response. At the heart of the citizen experience is a RAG-powered survival assistant built on Google's Gemini API, accessible through both text and voice. Rather than relying on Gemini's general knowledge alone, every response is grounded in a curated, verified emergency knowledge base flood safety protocols, evacuation steps, and local response procedures stored as vector embeddings in ChromaDB. When a user asks something like "water is rising near my house, what do I do?", the system retrieves the most relevant verified guidance and passes it to Gemini alongside the question, so the answer is grounded in real protocol rather than a generic AI response. The voice agent extends this further for moments when typing isn't practical someone fleeing rising water, someone who can't read well, or someone simply too panicked to type coherently. A user can speak their emergency directly into the app; their voice is captured, transcribed, and routed through the same Gemini powered RAG pipeline, with the response spoken back to them turning a stressful, wordless moment into a simple conversation: "Move to higher ground, the nearest shelter is 2.3 km away." The system is built with resilience in mind: the chatbot operates in two modes an online mode, where Gemini generates a live, grounded response using retrieved context, and an offline fallback mode, using local text-to-speech and cached ChromaDB retrieval when connectivity drops since floods often knock out networks exactly when people need guidance most. This reflects FloodOps' broader design principle: AI should assist and explain, not replace judgment. Just as SHAP makes the platform's flood-risk predictions explainable to officials, both the chatbot and voice agent are traceable back to real, retrieved source material ,making Gemini a transparent, trustworthy guide during a crisis, in whichever form, typed or spoken a person needs it in that moment.
