This book describes the LabVIEW-Arduino Uno simulations of the water table management modes in drainage and subirrigation. Chapter 1 of the book describes the theories of the drainage and subirrigation water table management modes with a description of an RC circuit used to measure the water table fluctuations during the management modes. Two derived equations; relating the soil physical parameters of the drainage and subirrigation modes with their respective RC parameters are mathematically derived. Chapter 2 describes the quadratic vector approximations for the water table management modes. Chapter 3 describes the analog of the water table management modes, and chapter 4 describes the interactive educational LabVIEW programming of the designed analog.
