Improving Tubewell Irrigation System Performance

Journal of Irrigation and Drainage Engineering, 1987
Results of a field investigation on 10 selected deep tubewell irrigation systems in Bangladesh are presented. Development and application of a service area model to predict the impact of various improvement options are also discussed. The majority of the deep tubewells in the study are found to be severely underused in both the duration and efficiency ...

Farmer's perspective on irrigation performance

Irrigation and Drainage Systems, 1990
Of the many client groups with interests in irrigation system performance, farmers are probably the least often considered. This paper attempts to explore the meaning of irrigation performance from their perspective, highlighting at the outset basic difference between this perspective and that of system managers.

Performance Evaluation of Irrigation Projects

2010
Any water applied above that needed to grow a crop is inefficient use of water. In order to determine how much irrigation water to apply, it is needed to estimate irrigation efficiency. There are many definitions of irrigation efficiency. Which one to use depends on which aspect one is interested in.

Performance Functions of Border Irrigation Systems

Journal of Irrigation and Drainage Engineering, 1988
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.

Overhead irrigation : a model to improve irrigation equipment performances

1996
A methodology has been developed to improve on-field irrigation equipment performances ; particularly to reduce water application heterogeneity in windy conditions. This methodology was set up following field experiments and simulations which were carried out with a model IRRIPARC.
