The water present in the soil and in the snow represents extremely sensitive data for various sectors. Monitoring soil moisture is crucial in agriculture to irrigate efficiently, save water and costs, and obtain a healthier and more abundant harvest. It is also important for fire and hydrogeographic instability simulations. The snow water equivalent is a crucial parameter for water availability forecasting for spring/summer and for hydroelectric power production. The ability to measure soil moisture in depth even in urban environments are a disruptive opportunity in the pre localization of leaks along aqueducts. The Cosmic-ray-neutron (CRNS) sensing technology, thanks to the great advantage to measure water in large scale, in depth without any contact with the soil could address all the problematic in a very disruptive way. Finapp make CRNS easy, compact and with a competitive price to make a complex and expensive technology like CRNS available for everyone. It will ensure a unthinkable water management solution at 360° from agriculture to water reservoir management and finally for localization of water leaks.
