It helps through falling leaves, these leaves serve as a giant sponge which controls the water to flow in lower level areas. The application generates a single disaster image called "fast-ready disaster map" from multitemporal SAR images.

However if it rains on a standing forest the trees or plants are responsible for holding an enormous amount of water. These wetlands act as a sponge in storms and inwhen the floods returned, the government did not have to expend resources in those areas.

Several communities accepted and the government, in partnership with the state, bought 25, properties which they converted into wetlands. Damage caused by floods can vary greatly according to the nature of the phenomenon at the origin of the flood.
