Abstract

Flood is one of the most destructive natural disasters in Tamil Nadu and needs proper forecasting systems to give early warning and mitigate the disaster. The present study, the Smart Flood Forecasting System is an AI and Machine Learning-powered system that incorporates four key datasets (Flood Inventory, Rainfall, Flood Impact, and IndoFlood events) with real-time weather data and automated voice notifications using Twilio. It used two complementary models: a Proposed Optimized Random Forest model, which was trained using curated datasets only, achieved 97.9% accuracy, 97.7% precision, 96.4% recall, and 97.1% F1-score using hyperparameter optimization and feature selection; and a Real Dataset framework, which used Logistic Regression, KNearest Neighbors (KNN), and The Flood Impact data added insights of the districts to the predictive features in terms of fatalities, injuries and the mean flood duration, enhancing the correlations between human displacement and the severity of floods. The high-risk cases identified during the risk assessment were more than 9,000 with a 60% probability threshold and automated voice alerts were successfully triggered in case of extreme flood scenarios. The system has integrated curated datasets, optimized algorithms, real-time weather integration, and instant communication mechanism, which makes it appear systematic, efficient, and scalable in disaster management to provide timely alerts and actionable insights to flood-prone areas in Tamil Nadu.

A Machine Learning-Based Early Warning System for Rainfall Level and Cloudburst Prediction

Extreme rainfall events and cloudbursts pose a severe threat to human life, infrastructure, agriculture and environmental sustainability particularly in regions of complex terrain such as northern Pakistan. Traditional Numerical Weather Prediction (NWP) systems struggle to resolve localized short-duration convective events because of their coarse spatial resolution and high computational latency leaving vulnerable populations with little lead time to respond. This study presents a full- stack machine learning -based Early Warning System (EWS) for predicting rainfall levels and detecting potential cloudburst events. To overcome the scarcity of high resolution localized meteorological records a physically informed data simulator was engineered to generate more than 145000 daily observations spanning nine years across 49 distinct locations covering temperature, humidity, pressure and wind parameters. Four predictive models Random Forest, Support Vector Machine (SVM), Logistic Regression and a hybrid Convolutional Neural Network with Bidirectional Long Short-Term Memory (CNN-LSTM) were trained and benchmarked on both rainfall magnitude regression and cloudburst classification. The CNN-LSTM model delivered the best performance with 99.1% accuracy, 98.5% precision, 97.2% recall, a 97.8% F1 score and an AUC of 0.99 while maintaining a low false negative rate. The trained intelligence was deployed through a Python Flask REST API for real time inference and a Risk Rating Score (RRS) algorithm was introduced to translate raw model outputs into four actionable color-coded alert levels (Green, Yellow, Orange, Red). An interactive React dashboard lets disaster management officials enter live weather metrics and instantly receive visual warnings. The proposed system provides a practical link between complex meteorological artificial intelligence and user-friendly emergency response platform synoptic macro scale forecasting.
