Simulating soil moisture under controlled drainage using HYDRUS (2D/3D)
Description: Soil moisture plays a major role in farm operations and plant growth and performance. Field measurement of soil moisture over a large area is tedious, expensive and time consuming. Consequently, hydrologic modelling can overcome the field measurement limitation. In the present study, HYDRUS (2D/3D) was used to simulate soil moisture content within the soil profile under controlled drainage in Southern Manitoba. HYDRUS (2D/3D) model numerically solves the Richard’s equation for water flow through variably saturated porous media. The model efficiency was assessed by using graphical comparison of both simulated and observed values, the coefficient of determination, the root mean square error, and the Nash–Sutcliffe modeling efficiency coefficient. Simulated values were in good agreement with field observed values. Hence, HYDRUS (2D/3D) is a useful tool to accurately simulate soil moisture content.
