Copernicus Sentinel-2 helps track changes in seasonal water of wetlands

Tracking spatio-temporal variations in flooded areas of wetlands is not an easy task, especially when they are characterised by a dense cover of emergent vegetation. Researchers in France developed a tool to monitor water in seasonal wetlands using Copernicus Sentinel-2 data, which exceed the performance of existing water indices.

The application of remote-sensing techniques for wetland mapping and monitoring is particularly useful because wetlands are dependent on water availability. Wetlands' high biodiversity and economic activities primarily rely on the timing and quantity of water (Lefebvre et al. 2015). Monitoring of flood patterns is therefore essential for understanding wetland evolution and management, leading to development and implementation of several spectral band response methods and indices, to aid water detection in wetlands.
