Introduction

The Keta Volta Basin, located in West Africa, faces significant challenges from both floods and droughts due to its hydrological variability and vulnerability to climate change. Remote sensing data plays a crucial role in analyzing and managing these extreme events. By using satellite imagery and data from sources like Sentinel-1, MODIS Land Cover, CHIRPS Daily Data and high-resolution DEMs, this project provides insights into flood risk mapping, drought forecasting, and the development of early warning systems. Remote sensing enhances the ability to assess trends, enabling more effective management strategies to mitigate the impact of floods and droughts.

Damage Assessment

Flood and Drought extents were generated using the JavaScript API interface in Google Earth engine
