Analytical Model for Border Irrigation Academic Article uri icon

abstract

  • This study develops a simple analytical model, using the volume balance approach, to simulate all phases of border irrigation. The surface and subsurface flow profiles in the advance phase are assumed to be of parabolic shape, and their coefficients are determined by conditions in the gradually varied flow region, rather than in the rapidly varied flow region near the advance front. The recession phases are simulated by using a simple iterative method based on Strelkoff's assumption, taking into account time-varying infiltration. Only one observed data set was used to calibrate the model, and 29 different observed data sets were used to verify the model. A comparison with some existing models shows that the model is simpler, more accurate (with less than 7% prediction error for all phases of the 29 test borders), and easier to apply. ASCE.
