Theoretical basis and significance of the variance of discharge as a bidimensional variable for the design of lateral lines of micro-irrigation

in order to support the theoretical basis and contribute to the improvement of educational capability issues relating to irrigation systems design, this point of view presents an alternative deduction of the variance of the discharge as a bidimensional and independent random variable. then a subsequent brief application of an existing model is applied for statistical design of laterals in micro-irrigation. the better manufacturing precision of emitters allows lengthening a lateral for a given soil slope, although this does not necessarily mean that the statistical uniformity throughout the lateral will be more homogenous.
