Abstract

The article presents a study on the effects of initial content of soil moisture, soil hydraulic parameters, and the observation on the ability of H-infinity filter (HF) assimilation to estimate the in situ water content of soil in Tai Lake, China. It states that the study administered the trial-and-error method to determine the weighting coefficient and the attenuation parameter of the error. It adds that there are poor simulation results when the soil hydraulic parameters are poorly predicted.
