  Theoretical analysis of slope effects on the spatial patterns of the pressure head profiles of an irrigation lateral is presented in the companion paper. Results of the analysis are evaluated here based on simulations. Simulations were conducted for data sets covering a wide range of lateral parameters. The results show that the pressure profile patterns of a lateral, and possibly the locations of the pressure extrema along the lateral, can be determined by comparing the negative lateral slope with the friction slope at the inlet and/or distal ends, confirming an important inference of the analysis. The simulation study also shows that the full range of variation of lateral pressure profile patterns can be differentiated into the three distinct categories defined based on theory. While results of the analysis developed in the companion paper are generally true, they nonetheless produc.. Read More»
