Abstract

We estimate soil moisture content variation for an agricultural field in Denmark using a cosmic-ray neutron probe and compare the results with point measurements using capacitance probes, and modelling result using a one-dimensional hydraulic model. The cosmic-ray data are in good agreement with modelled soil moisture content variation using measured/estimated meteorological variables (i.e. precipitation, potential evapotranspiration, and temperature) as well as unsaturated hydraulic parameters.
