Modelling of basin irrigation systems: A review

Abstract

Basin irrigation layouts are used extensively for irrigation of various types of crops worldwide. Basin irrigation is characterised by ground levelled to zero slope in both directions and each unit enclosed by dykes. Single closed level basins and sequential multiple basin layouts offer potentially high uniformity of application, reduced runoff and low labour requirements. Several simulation models have been developed to study the flow processes involved during an irrigation event in basin irrigation to improve the design and operation of these basin layouts. These simulation models are based on governing equations in the form of the full hydrodynamic Saint-Venant equations or the simplified..
