PROCÉDÉ ET SYSTÈME DE DISTRIBUTION D'EAU ET DE DÉTERMINATION D'HUMIDITÉ D'UN SOL

摘要

A method of spatially deriving the soil moisture at a selected location within an irrigation district to be irrigated, said method including the steps of using system identification techniques to produce an algorithm for evapotranspiration based on a predetermined selection from the following measured parameters: solar radiation spectrum, wind speed, temperature, humidity, crop factor, soil type, barometric pressure, irrigation historical data, and energy measurement from solar panels at each of a plurality of representative locations; calibrating said algorithm by direct measurement of the moisture in the soil at each of said representative locations by respective soil moisture sensors; and using measured parameters of rainfall, soil type, irrigation historical data and crop factor with said algorithm to derive or interpolate soil moisture at said selected location within said irrigation district.
