Abstract
Electrical analog simulation of the subirrigation process inside a classroom is a task that no researcher has ever performed. Therefore, the purpose of this research is to design an experimental setup within the classroom to create an electrical analog of the linearized transient partial differential equation describing subirrigation (seepage irrigation). An RC analog circuit controlled by an Arduino microcontroller, linked to software LabVIEW, is used to achieve this purpose. The analytically derived Fourier series solution of the linearized transient partial differential equation governing subirrigation is verified experimentally against the solution of Kirchhoff’s partial differential equation, which describes the unsteady current flow through the constructed RC circuit. The physical parameters (transmissivity and evapotranspiration rate) of the linearized equation are simulated as constants in the constructed RC analog. The agreement between the calculated and observed isochrones of the rising water table levels of the subirrigation process is excellent, indicating that both Fourier solutions are physically and mathematically identical. The constructed electrical analog demonstrates a pedagogical use for the versatile Arduino microcontroller. The power of analogs should form an integrated part of learning groundwater physics.
