With increasing anthropogenic activities and the escalating impacts of climate change, flood hazards have become more frequent and severe, causing extensive damage to crops, settlements, and infrastructure. Flood hydrologists have long faced challenges in accurately estimating flood depths-an essential parameter for effective disaster response and risk mitigation. Although optical and microwave satellite imagery have significantly advanced flood mapping by providing Continue Reading »

Sal forests cover 11 million hectares in the Indian subcontinent. They are important for the environment and the economy because they support biodiversity and provide a range ecological services including livelihoods of indigenous people. These forests face a major threat from an insect called the Sal Heartwood Borer, or "Hoplo". When these beetles multiply quickly, they kill thousands of trees. Continue Reading »

The Ramganga Dam Reservoir and Tehri Dam Reservoir are two important water storage systems in Uttarakhand that support hydropower generation, irrigation, flood control, and drinking water supply. Monitoring these reservoirs using SWOT (Surface Water and Ocean Topography) satellite data helps in understanding their hydrological behaviour, seasonal storage variability, and response to climatic conditions. The reservoirs were selected because they represent Continue Reading »
