Comparison of Two Nonlinear Radiation Models for Agricultural Subsurface Drainage

One of the basic functions of subsurface agricultural drainage systems is to avoid the establishment of a moisture regime adverse to crop development by means of the depletion of shallow groundwater and the timely evacuation of water excess stemming from overirrigation, rainfall, losses due to infiltration in channels and contributions from underground streams. In order to make an efficient water evacuation, it is crucial to know the way in which it moves in the soil so as to determine the water flow that can be removed from the porous medium by means of drainage with the corresponding variation of the aquifer level.
