Executive Summary : | The Indian Space Research Organisation (ISRO) is aiming to improve the predictive capacity of its Experimental Territorial Landslide Early Warning System (Te-LEWS) for rainfall-triggered landslides in India. The project aims to explore the applicability of the Soil-water Index (SWI) based Japanese early warning criteria to India within the framework of ISRO's Te-LEWS. The research will develop and improve SWI landslide early warning thresholds for Uttarakhand, India, and update it regionwide for operation during extreme rainfall 5 km 5 km grids and 3 km 3 km grids. Extreme precipitation-induced sediment disasters, such as slope failures, debris slides, and debris flows, occur increasingly in Japan and India. Climate science models project an increase in extreme rainfall events over Japan and a substantial increase in monsoon precipitation over the Himalayas in India, which are affected by catastrophic landslides every year. The project aims to introduce the successful applicability of the Japanese Early Warning Criteria to India, specifically Uttarakhand, by adopting novel numerical modeling approaches to address the challenges of limited historical records of landslides. The research will also explore the possibility of deriving early-warning thresholds for data-scarce regions. |
