Performance Functions of Border Irrigation Systems

Abstract

A set of design functions that relate system performance to design variables in graded border irrigation was developed and verified. A dimensional analysis approach is used to combine the independent variables into a reduced number of independent dimensionless parameters. A computer simulation model is used to obtain the variation of the dependent performance parameters with the independent dimensionless parameters. Dimensional analysis techniques are used to obtain functional relationships between each of the dependent parameters and the independent dimensionless parameters. Field data and the Soil Conservation Service's design charts were used to verify the developed quality parameter functions.
