To estimate series of water flows, it is required to collect a set of reliable stream measures, as accurate as possible, and to generalize them using continuous water height measurement from immersed sensors. Many methods are used to do so such as gauging by salt for conductivity, velocimeter based on Dopler radar ultrasound to draw the river...
